facts of life. I'm actually thumbing through one of your competitors catalogs and it just dawned on me. Why don't I just check out your website. Some of the prices I'm looking at in this magazine are making my head spin.
@@bbaaspencer1 I’ve had some good luck so far after a year and a half with one I bought from an eBay store seller...I found the cheapest I could cuz I’ve replaced it twice before already lol...so far this is the longest lasting one but I do drive a lot lol
They left off the #1 thing that will break that everyone has had happen. Center console breaks starting with the latch then eventually the whole thing. Brilliant move making the frame out of the cheapest plastic ever.
I bought a 2006 TrailBlazer LS with 150k miles in mid 2018 as a vehicle primarily to get to and from work. Since my ownership, the Check Engine light came on, trailing arm snapped and the door trims popped and snapped off. For the holidays I drove 1800 miles to California and eventually gave it to my parents since they wanted an off-roader for the desert. It still runs as of January 2022 with around 175k miles, it's just that every service/warning light comes on lol.
I had an 03 and I put 200k miles on it. I experienced almost all of these problems including multiple wheel bearings. Still was a good truck and would love to own an SS someday
My buddy has been experiencing the heater problem and I was like Cha Ching. I sent it right to him and he looked at the problem and sure enough these guys were right.
I just bought a 2003 Trailblazer with 110k miles. So much better than the newer 3.6L engines. I had a complete detail done and it looks almost new. My wife and 18 y/o son hated it before now they love it. So far it’s been a great buy.
My favorite break down incident was on the interstate at a gas station in the coldest part of winter..put fuel in got in and started it...went to put it in gear and it wouldn’t let it out of park...I sat there for a few hours waiting for a friend to bring me some tools so I could get to the release under the shifter which is how I got it to move again...spent $300 on two parts the book said it was needing...still didn’t fix the issue...it ended up being the grounding wire harness in the passenger side of the center console area by the glove box area..the screw holding it in place had loosened up just enough to cause the problems..spent two weeks unhooking my battery cuz I couldn’t get my key out of the ignition and having to use the release under the shifter to get it in and out of park...I was pissed when I found that loose screw...
I had linkage come off on it when it was 16 years old. It was just the rubber piece I side so I got some rubber o rings used in plumbing for 5 bucks forced two of them on and my linkage has been on for 3 years now lol.
Bought my 04 LS utility sport 4.3 blazer for $800 only 3 lights and none are check engine lights, has 150k runs and drives and she is amazing.❤ love Chevy so much
He forgot to tell you the #4 misfire is often from leaking hood seal, which allows rain to run off the windshield and collect on top the engine, and run down into the spark plug well
About a month ago my cylinder 1 ignition coil completely died on me. Keep in mind they were the original Delphi branded coils too so I'm surprised they've lasted 17+ years. I didn't bother just changing one out because it would just rainbow effect on the others so I replaced all of them.
Nice, I said it not too long ago you guys should do more trailblazer videos. You delivered. I'm actually learning these things blow through transmission fluid pumps as well. LoL. I'm actually so fed up doing swaps that I'm currently rebuilding mine with all the necessary upgrades to hopefully prevent it from happening again any time soon.
Bought 2005 TB LS in 2015. Replaced/repaired quite a few parts which included needed/required maintenance. Have 180k on it. Everything still works and we're still driving
I have a 02 trailblazer LT and just replaced all 6 ignition coils. Had a code for random multiple cylinder misfire. Turns out all 6 coils where original to the truck from 02. Replaced both front hubs starter,fly wheel front o2 sensor and other odds and ends. 107k on truck runs like a dream.
My 05 Trailblazer has 225k miles. I've had the fan clutch and fuel sensor problems. I replaced the fuel pump at same time as fuel sensor because it had 100k miles. Fuel pump was working but figured I'd go ahead and replace so I didn't have to pay the labor again. GM put out a list of approved gas brands. I started buying only those brands and never had another problem with the fuel sensor. Fan clutch has gone out twice. Overall it has been an excellent car. Still runs great. I'd buy a newer car if I could find one I liked as well as my old Trailblazer.
I have two of these, an 03 EXT and an 07. Bought the 03 with 211k for 2k with a pretty solid body with the intention of fixing it up, engine lost compression on #2 after 2k miles and needs everything so I bought an 07 with 116k for 6 grand. Been using the 03 for parts and its been a godsend. Just went through 2 blower motor resistors before I ripped the blower motor out of the 03 and now it runs great.
400 Thousand !!! Good Lord , i just got a 2003 4.3 Blazer LS with 179 Thousand miles on it , Runs Great , but man i was really beating myself up over the milage i have , but I'm older and used to motors maybe going 200 thousand , HaHa , Thanks for your good cheer , it will outlast me , with enough repair money and if gasoline is still around !!!
I'll add a few things I found with the 02-09 trailblazer. 1. With the 4.2, the intake manifold bolts can become loose causing a massive vacuum leak which will give you codes for a misfire and one bank running too rich. To fix just tighten all 10 bolts around the intake manifold 2. The rear upper control arms can come into contact with the sway bar link, snapping it. To fix, either get new control arms or relocate the upper link to the other side of the mount, you will need aftermarket sway bar links. 3.The air pump, the stupid little thing that pumps air into the exhaust, will go bad and throw a code. It doesn't really matter, fix it if you want. Quality of life mods that I have done. 1. Chevy tahoe springs in rear, trailblazer ext springs in the front. Gives you more payload capacity and slightly better ride height, be sure to pair each with some bilstein shocks. 2. When doing a full brake job, buy trailblazer ss caliper brackets, pads and rotors for the front, only if you have 17 inch wheels. If you are feeling very special, 02 tahoe dual piston calipers fit in the rear with slight modification to the bracket and dust shield. The rotors are a perfect fit except for bolt pattern, you can just drill new holes.
My Only Purchase of a New Vehicle was my 2002 AWD Chevy Trailblazer LTZ. I bought it New from the Chevy Dealership Nov. 2001. Immediately, I had a Problem with the AWD System. An example: I switch the vehicle into AWD during inclimate weather; rain, snow, etc., otherwise I use 2wd..(have never towed anything or used it off raod). Well I was having horrible trouble with the vehicle not going into the desired mode of transmission. I brought it back to my dealership about 5or6 times w/o the proplem being fixed(staying in 2wd, or going into full time 4wd) and without being given a free loaner. You would think that because the dealership didn't fix the trouble, that they would give me a complimentary loaner, but no they did not! Anyway, one of the serviceman rubbed me the wrong way and I decided to put in for a Lemon Law of which the vehicle qualified(same problem not fixed 4x in a given time span). After filing my paperwork for the Lemon Law Vehicle, they made me jump through hoops at Corporate to discourage me, but to no avail, I marched forward. I was denied time and again for a replacement or a refund, after showing proof. When they offered me 1 payment to go away, I respectfully declined. I wanted a replacement vehicle at this point. I paid over $40,000 for a new problem free SUV, and all I got was a headache. Forward to the end, in hindsight, I should have had a lawyer handle it. Chevrolet screwed me over, they said they would fix it to my liking; they didn't, and the period to act ran out without them fixing what they told me they would do. I can't believe that Chevrolet would treat me this way. I was always a Chevy Guy, with my Big Block Nova SS & my Big Block Chevelle SS in the muscle car years. Don't bend down for that droped wrench, you'll might just get rear ended! I guess this is called Life's Lessons! 😢
@@tylerpenberthy8523 my guess on mine is the valve seats like he said everything else is done. 158 *** miles just turning off at random occasions? Any guesses or is the valve seat the right one this time ?
Any ideas on where to buy speaker. My dad has factory speakers and he has the 2007 model. He has a Ford Flex so he passed the suv to me. Both rear speakers don’t work front two are blown
Main issues were stock stereo and blower motor resistor. I have about 135k miles and with regular maintenance, my 05 Trailblazer is a blessing. The weird thing is I have to hold the gas pump manually when I fill because it clicks the gas pump off if I leave it in like in a normal car.
Mine did similar.. the nozzle has to be STRAIGHT IN, or it kicks off. That's why when you HOLD it so, it runs ok. I found, pulling the fuel filler hose over and "hanging it" against the left side on the pump.. so the hose is supported and filler aimed straight in, it works fine. Hard to explain, but if you look at it once there.. you'll get the idea.
The gas pump issue has to do with fuel vapor canister, or any corresponding part. If any of is clogged up, and can't breath, it will sense it is (drowning) and shut off the auto fuel pump at the station.
i've had my 07 for about 3 years now and have already done the front driver side wheel bearing and now i have lost number 4 fan speed. I've also had to replace the VVT actuator (easy), water pump (easy) and rear diff pinion bearings (not easy).
The video described every single issue I'm having with a trailblazer that I just bought....Thanks for the Information, It helped a lot with figuring out what was happening!
It failed to mention that it goes through ball joints like crazy. Because of how heavy the front end is I'd defiantly recommend putting in better struts on the front as the design of it puts so much pressure on the ball joints.
Lo máximo la trailblazer , aca en Peru viajo por las Lineas de Nazca con la chevrolet trailblazer ext, algunas veces me he encontrado con luces extrañas que me han seguido y en otros casos frente a frente, muchas historias increíbles tengo con la chevrolet trailblazer ext. SALUDOS
I also have a 07 260 thousand best car I’ve ever owned..Looking for a Creame puff like this one...It’s about worn out now just replacing stuff all the time but for 250 thousand no problems I’m gonna bury her in the back yard when or if she ever kicked..I love it
Same here 🤣 although I have a reduced engine power light that I can’t seem to get rid of & no ac, other than that I’m surprised mine is still running good. I love that truck
I love the GMT360 platform. I prefer them over the newer SUVs. Only gripe is the fan clutch, not sure why GM did not go with dual electric fans to cool it. I have had an '02 TB that served me well until an old lady that should have not been driving t-boned me. My rear door was done but her van was totalled all the way to the front dash. Good thing these are still on frame or would have been much worse. I currently have an '06 Saab 9-7X which is a Trailblazer with Saab skins. Love it but it has too many quirks cause of all the luxury add ons. Currently looking for another TB to add to my arsenal. Maintenance is so easy and the in-line 6 is almost bulletproof. Add a tune from PC of NC and it is a whole new SUV.
I have a Saab 97x with the 4.2 which is essentially the same vehicle. In 110,000 miles since new, I've replaced my wheel hub assemblies a few times (referred to as wheel bearings in the video). I strongly recommend Timken as they have lasted the longest at around 50,000 miles. So far, haven't had any of the other issues, but from what I can recall I have had to replace 1) Rusted out brake line and transmission line 2) Idler pulley 3) Power Steering Cooler 4) Suspension air bags and compressor (twice so far) 5) ABS sensor failure 6) Alternator 7) Crankshaft position sensor (likely due to extended oil change interval) 8) Starter 9) O2 sensor 11) Seat lumbar support failure, and the normal maintenance of brakes, tires, battery, belts, fluids, spark plugs, etc. It's not exactly Toyota reliable, but it's been fairly good and I like the ride quality, size, features, comfort and best of all, it has been paid for for 11 years. Important aspects IMHO, change transmission, differential, and transfer case fluids at maintenance intervals, and oil every 5k.
I've had around 7 issues with mine and it was none of these, Ignition switch, Radiator Cooler, Fan door in the back keeps popping from being stuck, Vehicle was in Limp Mode when I bought it, Turned out to be a severed wire that connects at the top of the radiator for the fan.
I've owned these for a long time and I never heard of problems with the valve seats. Typical reason for misfires is a bad coil. And what you're pointing at is the Secondary Air Injection System valve, not an EGR, which it doesn't have. It is a high failure system that causes other issues.
I've had to replace both front hub bearings and the blower motor resistor. Replacing the hubs bearings was easier than replacing the thermostat. I had rattles going over bumps and it was because of both front and rear sway bar links being worn out. The hardest job was replacing both power steering lines. Where the lines are held down by rubber or plastic bracket on top of the left fender well, they get rusted out. Trying to bolt the lines onto the steering box is tricky because only a small bolt holds the lines in, and you surely don't want to break that off or you're screwed. Keep checking for leaks
The fan clutch problem would have been expensive, but I just rigged it so it was always engaged. Didn't seem to cause any issues. The other issue that seems to be common is the electrical system relating to the taillight. How many trailblazers have you seen with taillights out?
On my 04 with 4.2L it was the rack and pinion steering and both front wheel bearings after those easy fixes this truck has been a dream just over 100,000 miles.
I bought an 06 Trailblazer not long ago. I have replaced the blower motor resistor. I'm gonna turn the day I bought it if I ever have any of these major problems he was talking about!
I got my 06 Trailblazer in February. I've put on a new set of tires bc the front were bigger than the back, replaced oil pressure sensor and the VVT solenoid. I've got a really good oil leak to track.
Resistor and Fan Clutch (and water pump twice).. and valve cover gaskets and 3 coils. Have a 2002 with 220k. Factory hubs, alternator, ac compressor, rack... it’s been great.
Bought my 2005 TrailBlazer four-wheel drive 2 years ago it had 148,000 mi first got it I replaced injector, changed the oil and it was good to go. I'm at 314,492. I drive approximately 170 miles a day. Change oil every 3-4 weeks or 3000 to 4000 miles. Great vehicle! However, I live in Mississippi the roads are terrible! At 175,00 replaced right top control arm. I am picking up another one today, I bought the life time warranty so no charge today. Within the last month ( as time and money allowed) I have replaced both sides upper and lower control arms ball joints, inner and outer tie end rods. I replace my break pads every 4-6 months. I've replaced both back break rotors, and one back break caliber. I have gone through 6 sets of tires and too many patches and plugs to count. I love my truck. Said I would drive it till the wheels fell off. Well, I lied!!! Right front wheel feel off last month... I put new tie end rods on it and I'm still driving it. God blessed me with this ride!!! Hope it goes another 300,000. I fix everything as soon as it starts s sound. NOW.. I need help. Have a low hum about a week now. Getting louder and sounds like something is rotating. Several guys at different shops have did the shake test said hub feels fine. I know I still need to replace shocks and sturts. On my to do list next week. Hum reminds me of an old 4x4 Jeep my uncle had that was deer camp ONLY condition. Anyone remember those from late 78- early 80s? 😂
Besides the trans lines and power steering lines needing replaced in the salt belt, and an occasional 14v reference wire that shorts out, you can expect 300k or more from the 4.2 with regular maintenance.
Have 2002 4 wheel drive bought in 2001. Had to replace front wheel drive shaft, fan clutch, rotted trans lines, front wheel bearings plugs, replaced all coils, spark plugs, shifter connector and vvt. Runs like a top and average 19+ a gallon. Plan to keep another 20 years 😅
Past couple of years I've had issue with the Oil Sensor. Driving my 6-cyl 2005 model at 45-55 and then coming to a stop the Oil Pressure gauge will flatline, the engine idle becomes rough, and if I don't manually accelerate the engine the car will stall. I've had my mechanic chase after this one and we've replaced/adjusted everything up to the Oil Pump (sensor, connectors, etc.). There are no issues at all with the engine... no taps, no misses. Mechanic states that the engine appears to not be oil-deprived because it runs so well. It is so random that when vehicle was left for days and driven by mechanic, he was not able to experience it. Just not willing to fork the $$$ to replace oil pump if it's not the real reason for the issue.
Sounds like the trouble I had with my Evap Sensors. Is it worse in the winter or generally cold. And when you fill up your tank do you let the stop and put the hose up or do you keep filling it up afterward to get more fuel in. If so, you definitely clog the Evap at the tank. I had to change that and the one at the engine to make it stop. if you search trailblazer evap in youtube, you'll find a few videos on it.
You forgot the infamous: battery replacement causes air to not come out of vents - always keep power to system when replace battery, or the actuator for the main vents will strip its gears. Known defect, should’ve been a recall.
I had a 2004 Trailblazer. Kept it until 2019. I replaced THREE front wheel bearings. I started to get $100 dollar'd to death with repairs. For a few years there, it was $1000 in repairs per year. And it was a gas hog. Then finally, the car would shut off while I was driving. 1st time was driving 70mph on an interstate. Had to have it towed. It felt electrical. I replaced the ignition switch. Otherwise, car repair place couldn't find the problem. No 'check engine' light. It shut off on me 5 times in 500 yards. (finally made it back home) I tried to drive it to repair shop, got 50 yards away from home and it shut off. Car wouldn't start until the next day. I backed it up to my house, called a junkyard and had them come get it. Trailblazers are notorious for electrical problems and I'm not going to hunt down one on a 15 year old car.
I've replaced the ignition switch 4 times in my 07, very faulty design in those. But if you order the 2nd gen version of the switch, it holds up far better (with the black and grey colouring on the unit). Changed my water pump and block heater and driver front wheel hub. The passenger front is about to start going soon...and the alternator too. Also thrown a couple of new batteries in it over the years. Since I plunked new plugs in it, the mileage has been way better as well. Mine has 187,000 Km on it and other than a some minor issues, it still runs very well and I live in Canada where the winters beat the hell out of vehicles every year.
They're an ok suv. I have had one of these before. I never had any issues with mine. I dont drive it hard like its a pro street car though. 😂 My only complaint about these suv's would be the god awful unstable steering. (Thats what made me sell the one i had.) They're good and reliable. Dont change lanes fast in them though. The body roll is insane.
I have a '03 with over 250,000 miles and I have had all except the fourth issue. The fan clutch, hub bearings I had to change twice but they are easy to do. At the moment I am replacing the transmission. It has taken me over a year to find one that was not over $1000.00. I hope it works. LOL
I got a 2004 LT only 85k miles for 2500 at an auction..all i needed was to change the gear shifter...clean the throttle body... new brake ps and rs and this truck has been great had it for last 2 months and i love it i was lucky came with a bad ass blue interior light was already tinted and had a touch screen head unit lol never had suxh a steal like this definitely put my charger up untill summer now that i got this bad boy
I discovered the Blower motor resistor "wiring harness" would fry out because factory installed the gage of wire wasn't correct. Many forums and videos talk about it should have had a recall it was such common problem. I've a 2005 Chevy Trailblazer and number 5 highest setting didn't work. I found a perfect match blower motor harness on ebay. I replaced last summer and #5 still blowing strong.
My personal list #1 ignition switch (3 in the past 4 years) #2 front wheel bearings (2 sets in the past 4 years) #3 headlight relay (2 in the past 4 years) #4 sway bar endlinks (2 sets and they still rattle)
So funny. As I watch this video all five I have replaced or need to. Whenever under 50 in Florida my 07 is having problems starting. It starts turns over shuts off then takes forever cranking but will always start. Definitely something bad going on though.
i have a 2004 ...I think i got it with about 100k and now it has over 250 i think... But i've replaced the bearing multiple times (buy good quality) and I was getting misfires every year which turned out to the coil packs. The blower motor resistor has been replaced as well. The power steering lines and transmission cooler and lines!! I've replaced all four calipers as well... But the main thing i seem to have issues with the most...the issue that seems to come up every year, is the blend doors for hte A/C. Every year, it somehow stops working or gets stuck...or something. It's only blowing at the feet, or now it seems to be letting heat in at the same time the AC is on..... This is probably the most annoying thing about this car. Cuz i never find out that this mess is acting up, until i need it
You could try and buy new weather stripping or try what I did, look for this like styrofoam straw type material and run it through the opening in the weather stripping
Dash cluster going crazy or the vehicle stalls or both! If you get out and shake the vehicle it will start again? Pull the rear interior panel on the driver side and check the wiring harness that runs along the bottom behind it! It rubs in an area that will ground out the harness! If you're experiencing this issue pull the cup holder out and pull up on the panel you'll see the dash goes back to normal.found that to be an issue on 4 trailblazers with that issue I've worked on.
Don’t forget about the rear upper control arms and mounts. The arms are thin as paper and snap. The mounts hold salt in them and they rot out. I paid $1400 to have arms and mounts replaced by a welder.
@@arnolddennis9753 yeah that's probably a good buy. As long as there was some maintenance done it should be fine. Either engine option is good, I have the 4.2.
The transmissions in these are pretty solid. I've experienced a few that needed solenoids to cure hard shifts, but the transmissions themselves are generally not problematic.
Here's one that should have been number six. The hood gasket... Causes water to leak down onto the engine block and fills the holes were the coil packs sit on top of the spark plugs. The water will eventually leak over time down until the spark plug and rust them out giving you misfires and check engine lights. You have to replace your hood gasket Plus your coil packs and plugs.
I put a piece of door weatherstrip to deflect water to either side instead of buying GM’s redesign of their original goofy hood seal. How long has this company been building trucks FFS?
So I have a o4 trailblazer while I'm driving down the road. All dash lights come on , all the gadges drop but the windows won't role down the stereo goes off. . When I turn suv off the security light stays on. Any suggestions
My '04 has several problems but still runs like a champ. Check engine light, shocks needs replaced, my SUV rocks left to right when I take a slow sharp turn and the tires feel like they're slipping while turning slow and sharp. Rear passenger window fell, water or something is getting under my front passenger floor mat keeping it moist and gross. I clean it up..it comes back! And my AC has a leak or something in it. It was professionally serviced 2 years ago and it stopped after getting an oil change at a private shop 🤔
I have a 2002 Chevy Trailblazer with 310,000 on it. I have replaced 3 fuel pumps, exhaust manifold, power steering line-hose, fan clutch, 2 upstream O2 sensors, 1downstream O2 sensor, catalytic converter, water pump, 1 u-joint, 3 sets of spark plugs, 5 coils. Lots of oil filters, oil, fuel filters, air filters & tires. I am the second owner, I know them, they took great care of this vehicle. I bought it with 105,000 miles on it. It still has the original front & rear brakes pads & disks. This gets used for trips to town, 100 miles, Billings for medical 325 one way. We just bought a 2013 GMC Terrain so the Trailblazer will not be used for trips anymore. I also have a 1969 Chevy C10 with 300,000 on it that is a daily driver. I bought it with 110,000 miles on it. Keeping up on the maintenance, oil, filters, fluids, tuneups pays off in the long run. Hello from north east Montana. 10 miles from the Canadian border.
I have the blower issue. When I first got my 06, fan setting 5 didn't work. It was fixed and then recently during this winter 4 and 5 stopped working. I got 4 back by banging on the top of the dash.
Been waiting 8 years for the fuel pump to go out or get weak so I can fix the fuel level sensor inside the tank…not gonna bother until it goes out…just track ur mileage ….ive had every last issue mentioned plus a ton more …wish they had quality after markets to replace these planned obsolescence parts they used so that it’s not always needing another part replaced because it’s been 3 years and the parts are all garbage that wear out fast with minimal use….
I've got a 2oo5 I bought it four yrs ago for 4k...and I've put 55k on it....142k now been a great vehicle....major buy rack and pinion...and a few bearings..😂
My problems with my 200,000 mile plus 2004. Fuel pump. That was a real pain in ass, back and knees. Good job putting it on the top of the tank. Bad job not making a access plate to it. Guess it would have taken $2 to make one and 30 seconds to fasten it down. The entire dash and modules. Speedo and RPMs are a sometimer. Heat gauge still works. oil pressure still works. Dash lights nope. Just plugged in a red Led strip and cut piece card board so it would not blind me at night. Now I can see it when the sun is the wrong position in the day time. The heat works on or off. A/C works the same way. Replaced the module with a fan switch. Locked all the control doors open. The control for the heat a/c still works. Probably because I only use it in two positions. Note if the cabin was well designed as 1969 suburban. Fan on/off is all you would need anyway. Turn the heat full. Roll down the road. Get to hot turn the fan off. Same with the a/c get too cold turn fan off. As long as you are rolling you got heat or A/C. But why no vents? Guess cables and a flap through a vent system to fresh air was to difficult to engineer. Also don't need a module to replace it. The rear modules. The control in the rear for the rear window heater and wiper. The daytime running lights control module. Replace that with a 8 feet of 16 gauge wire to each headlight and two 30 amp relays connected to key on relay in the under hood relay/fuse box. Front differential bearing. Solution remove the drive shafts. Don't use AWD anyway. Thought it was the front wheel bearings starting to go. Now I got two good used spares. Anti lock brakes acting up. Removed the 60 amp fuse. Replaced the power steering rack and front suspension bushings. Cracked exhaust manifold. Still cracked just use a beer can to cover the burnt out heat shield portion and screw another in it place when needed. It quiets down when the engine warms up anyway. Rusted out gas filler neck. That was fun. Rusted out spare tire lift safety lock. Rusted out spare tire wheel. Never used. Not been replaced. And last driver side window control module corrosion. Why put it where the dog can operate it anyway? Ist noticed not going to fix code? Temperature sensor buried in the oil pan. Makes sense, put it where you have pull the engine to replace it. So the olde lady does not understand why I won't buy a new cute 2021 with a center distraction screen and a automatic back scratcher. Guess the 1990-2000 engineering grads went to the Bag of Rocks Engineering University. BUT the EPA, CAFE, and NTSB Engineers also went there on the short bus. The most important safety and economy operating device is in-between your ears.
My 2002 drains out battery. Apparently headlights turn on overnight on their own and kill the battery. I've taken it to three different mechanics and none where able to fix the problem.
Clutch fan, after changing the clutch fan I still had the same problem. Found out it’s the sensor. The sensor is located behind the alternator. Fun fun fun.
I am selling my 2003 trailblazer. Great looking body brown in color has 137,000 miles. Air and heat works never had any problems..bought it from the head guy at Chevrolet dealership...his wife bought a new car....back seat looks like new no tears.. tires decent.... paint still looks good....Make an offer...I just bought a 2022 Chevy Equinox...did not want to trade it in

I'm surprised you didn't mention the vvt solonoid
Variable Timing solenoid! Everyone goes bad!
@@bbaaspencer1 I’ve had some good luck so far after a year and a half with one I bought from an eBay store seller...I found the cheapest I could cuz I’ve replaced it twice before already lol...so far this is the longest lasting one but I do drive a lot lol
is the upper tortion bar on the rear a common problem? on our bolth broke off the frame and one broke in half at the same time
They left off the #1 thing that will break that everyone has had happen. Center console breaks starting with the latch then eventually the whole thing. Brilliant move making the frame out of the cheapest plastic ever.
My TrailBlazer has been very good to me over the years its at 204k miles atm still running smooth as ever.
Mine has too. 230k miles
I changed the camshaft sensor without removing the battery . Now she won’t start

My dad just gave me his 2004 trailblazer he had it for 18 years…it still runs like a new car

The only problem I have with my fuel sensor is that it falls from one side to the other too quickly
That's Brandons fault
I bought a 2006 TrailBlazer LS with 150k miles in mid 2018 as a vehicle primarily to get to and from work. Since my ownership, the Check Engine light came on, trailing arm snapped and the door trims popped and snapped off. For the holidays I drove 1800 miles to California and eventually gave it to my parents since they wanted an off-roader for the desert.
It still runs as of January 2022 with around 175k miles, it's just that every service/warning light comes on lol.
I had an 03 and I put 200k miles on it. I experienced almost all of these problems including multiple wheel bearings. Still was a good truck and would love to own an SS someday
This videos sometimes are like a gold mine
My buddy has been experiencing the heater problem and I was like Cha Ching. I sent it right to him and he looked at the problem and sure enough these guys were right.
Frrrrr
Yeah, fools gold.
Trailblazers, one of the best SUVS out there.

I just bought a 2003 Trailblazer with 110k miles. So much better than the newer 3.6L engines. I had a complete detail done and it looks almost new. My wife and 18 y/o son hated it before now they love it. So far it’s been a great buy.
Shifter cable linkage breaking was a big issue too.
My favorite break down incident was on the interstate at a gas station in the coldest part of winter..put fuel in got in and started it...went to put it in gear and it wouldn’t let it out of park...I sat there for a few hours waiting for a friend to bring me some tools so I could get to the release under the shifter which is how I got it to move again...spent $300 on two parts the book said it was needing...still didn’t fix the issue...it ended up being the grounding wire harness in the passenger side of the center console area by the glove box area..the screw holding it in place had loosened up just enough to cause the problems..spent two weeks unhooking my battery cuz I couldn’t get my key out of the ignition and having to use the release under the shifter to get it in and out of park...I was pissed when I found that loose screw...
YES LMFAO
one of the biggest issues surprised it was not mentioned in the video
yep i had to replace the one on mine.
I had linkage come off on it when it was 16 years old. It was just the rubber piece I side so I got some rubber o rings used in plumbing for 5 bucks forced two of them on and my linkage has been on for 3 years now lol.
Yep. I had all these problems on my 2006 with 400,000 miles except the misfire was from a bad coil.
Wow that many miles. These trucks must be tanks!
Owning a Envoy I can confirm, the fan clutch and resister are very true 😂
Bought my 04 LS utility sport 4.3 blazer for $800 only 3 lights and none are check engine lights, has 150k runs and drives and she is amazing.❤ love Chevy so much
Amazing!
My ‘05 Trailblazer had a misfire yesterday and it was the #4 coil!!!!
Yup, coils are bad on them. Had mine replaced and it runs much better.
He forgot to tell you the #4 misfire is often from leaking hood seal, which allows rain to run off the windshield and collect on top the engine, and run down into the spark plug well
+Gerald Evans Thanks for the tip!
Mine was number one shorting out due to water collecting when my wife parked nose down on an incline whenever it rained.
About a month ago my cylinder 1 ignition coil completely died on me. Keep in mind they were the original Delphi branded coils too so I'm surprised they've lasted 17+ years. I didn't bother just changing one out because it would just rainbow effect on the others so I replaced all of them.
Nice, I said it not too long ago you guys should do more trailblazer videos. You delivered. I'm actually learning these things blow through transmission fluid pumps as well. LoL. I'm actually so fed up doing swaps that I'm currently rebuilding mine with all the necessary upgrades to hopefully prevent it from happening again any time soon.

Bought 2005 TB LS in 2015. Replaced/repaired quite a few parts which included needed/required maintenance. Have 180k on it. Everything still works and we're still driving
I have a 02 trailblazer LT and just replaced all 6 ignition coils. Had a code for random multiple cylinder misfire. Turns out all 6 coils where original to the truck from 02. Replaced both front hubs starter,fly wheel front o2 sensor and other odds and ends. 107k on truck runs like a dream.
i have a 07 ls and i love it.it gives me a great smooth ride
I’ve got a 08 blazer lt has 324k and runs and shift smooth as ever
My 05 Trailblazer has 225k miles. I've had the fan clutch and fuel sensor problems. I replaced the fuel pump at same time as fuel sensor because it had 100k miles. Fuel pump was working but figured I'd go ahead and replace so I didn't have to pay the labor again. GM put out a list of approved gas brands. I started buying only those brands and never had another problem with the fuel sensor. Fan clutch has gone out twice. Overall it has been an excellent car. Still runs great. I'd buy a newer car if I could find one I liked as well as my old Trailblazer.

I have two of these, an 03 EXT and an 07. Bought the 03 with 211k for 2k with a pretty solid body with the intention of fixing it up, engine lost compression on #2 after 2k miles and needs everything so I bought an 07 with 116k for 6 grand. Been using the 03 for parts and its been a godsend. Just went through 2 blower motor resistors before I ripped the blower motor out of the 03 and now it runs great.
Just turned 400,000 on my 2002 TB. Love this truck. No issues at the moment.
400 Thousand !!! Good Lord , i just got a 2003 4.3 Blazer LS with 179 Thousand miles on it , Runs Great , but man i was really beating myself up over the milage i have , but I'm older and used to motors maybe going 200 thousand , HaHa , Thanks for your good cheer , it will outlast me , with enough repair money and if gasoline is still around !!!
Let's see a odo pic. The body and trim on the clunkers don't last that long.
I'll add a few things I found with the 02-09 trailblazer.
1. With the 4.2, the intake manifold bolts can become loose causing a massive vacuum leak which will give you codes for a misfire and one bank running too rich. To fix just tighten all 10 bolts around the intake manifold
2. The rear upper control arms can come into contact with the sway bar link, snapping it. To fix, either get new control arms or relocate the upper link to the other side of the mount, you will need aftermarket sway bar links.
3.The air pump, the stupid little thing that pumps air into the exhaust, will go bad and throw a code. It doesn't really matter, fix it if you want.
Quality of life mods that I have done.
1. Chevy tahoe springs in rear, trailblazer ext springs in the front. Gives you more payload capacity and slightly better ride height, be sure to pair each with some bilstein shocks.
2. When doing a full brake job, buy trailblazer ss caliper brackets, pads and rotors for the front, only if you have 17 inch wheels. If you are feeling very special, 02 tahoe dual piston calipers fit in the rear with slight modification to the bracket and dust shield. The rotors are a perfect fit except for bolt pattern, you can just drill new holes.
My Only Purchase of a New Vehicle was my 2002 AWD Chevy Trailblazer LTZ. I bought it New from the Chevy Dealership Nov. 2001. Immediately, I had a Problem with the AWD System.
An example: I switch the vehicle into AWD during inclimate weather; rain, snow, etc., otherwise I use 2wd..(have never towed anything or used it off raod). Well I was having horrible trouble with the vehicle not going into the desired mode of transmission.
I brought it back to my dealership about 5or6 times w/o the proplem being fixed(staying in 2wd, or going into full time 4wd) and without being given a free loaner. You would think that because the dealership didn't fix the trouble, that they would give me a complimentary loaner, but no they did not!
Anyway, one of the serviceman rubbed me the wrong way and I decided to put in for a Lemon Law of which the vehicle qualified(same problem not fixed 4x in a given time span).
After filing my paperwork for the Lemon Law Vehicle, they made me jump through hoops at Corporate to discourage me, but to no avail, I marched forward. I was denied time and again for a replacement or a refund, after showing proof. When they offered me 1 payment to go away, I respectfully declined. I wanted a replacement vehicle at this point. I paid over $40,000 for a new problem free SUV, and all I got was a headache.
Forward to the end, in hindsight, I should have had a lawyer handle it. Chevrolet screwed me over, they said they would fix it to my liking; they didn't, and the period to act ran out without them fixing what they told me they would do. I can't believe that Chevrolet would treat me this way.
I was always a Chevy Guy, with my Big Block Nova SS & my Big Block Chevelle SS in the muscle car years.
Don't bend down for that droped wrench, you'll might just get rear ended!
I guess this is called Life's Lessons! 😢
The funny part is I have replaced all of these things lol
me too, all except the valve seats. 286,xxx and still running STRONG. only part on the engine I ever had to replace was an ignition coil.

Any ideas on where to buy speaker. My dad has factory speakers and he has the 2007 model. He has a Ford Flex so he passed the suv to me. Both rear speakers don’t work front two are blown
I bought mine 8 years ago for 2300 dollars. It has 300,000 miles on it. If something was to happen to it I would definitely buy another.
Main issues were stock stereo and blower motor resistor. I have about 135k miles and with regular maintenance, my 05 Trailblazer is a blessing. The weird thing is I have to hold the gas pump manually when I fill because it clicks the gas pump off if I leave it in like in a normal car.
I feel insane. Everyone gets to automatically fill gas, and even with it clicked, it clicks off meaning I have to manually fill every time.
I have to do the same thing
Mine did similar.. the nozzle has to be STRAIGHT IN, or it kicks off. That's why when you HOLD it so, it runs ok. I found, pulling the fuel filler hose over and "hanging it" against the left side on the pump.. so the hose is supported and filler aimed straight in, it works fine. Hard to explain, but if you look at it once there.. you'll get the idea.
The gas pump issue has to do with fuel vapor canister, or any corresponding part. If any of is clogged up, and can't breath, it will sense it is (drowning) and shut off the auto fuel pump at the station.
i've had my 07 for about 3 years now and have already done the front driver side wheel bearing and now i have lost number 4 fan speed. I've also had to replace the VVT actuator (easy), water pump (easy) and rear diff pinion bearings (not easy).
2009 LT...156k miles...normal maintenance - brakes and wheel bearings only real issues....all replaced twice....still I must say worth every penny....
#4 coil has gone on twice. This time I'll try cleaning. Not sure where to clean but I'll look.🎉🎉

The video described every single issue I'm having with a trailblazer that I just bought....Thanks for the Information, It helped a lot with figuring out what was happening!
It failed to mention that it goes through ball joints like crazy. Because of how heavy the front end is I'd defiantly recommend putting in better struts on the front as the design of it puts so much pressure on the ball joints.

@@arnolddennis9753 Definitely
What about the front axle going through the oil pan
That engineer should get the Darwin award
I love the GMT360 platform. I prefer them over the newer SUVs. Only gripe is the fan clutch, not sure why GM did not go with dual electric fans to cool it. I have had an '02 TB that served me well until an old lady that should have not been driving t-boned me. My rear door was done but her van was totalled all the way to the front dash. Good thing these are still on frame or would have been much worse. I currently have an '06 Saab 9-7X which is a Trailblazer with Saab skins. Love it but it has too many quirks cause of all the luxury add ons. Currently looking for another TB to add to my arsenal. Maintenance is so easy and the in-line 6 is almost bulletproof. Add a tune from PC of NC and it is a whole new SUV.
I have a Saab 97x with the 4.2 which is essentially the same vehicle. In 110,000 miles since new, I've replaced my wheel hub assemblies a few times (referred to as wheel bearings in the video). I strongly recommend Timken as they have lasted the longest at around 50,000 miles. So far, haven't had any of the other issues, but from what I can recall I have had to replace 1) Rusted out brake line and transmission line 2) Idler pulley 3) Power Steering Cooler 4) Suspension air bags and compressor (twice so far) 5) ABS sensor failure 6) Alternator 7) Crankshaft position sensor (likely due to extended oil change interval) 8) Starter 9) O2 sensor 11) Seat lumbar support failure, and the normal maintenance of brakes, tires, battery, belts, fluids, spark plugs, etc. It's not exactly Toyota reliable, but it's been fairly good and I like the ride quality, size, features, comfort and best of all, it has been paid for for 11 years.
Important aspects IMHO, change transmission, differential, and transfer case fluids at maintenance intervals, and oil every 5k.
GMC Envoy, Oldsmobile Bravada, same exact platform
@@shadowopsairman1583 As is the Isuzu Ascender and the Buick Rainier.
These videos would be great if you could recommend aftermarket replacements.
1A auto Rock Auto Parts Geek. Many of our TB parts came from there
For me it's a great vehicle. I love the my trailbleazer.
I've had around 7 issues with mine and it was none of these, Ignition switch, Radiator Cooler, Fan door in the back keeps popping from being stuck, Vehicle was in Limp Mode when I bought it, Turned out to be a severed wire that connects at the top of the radiator for the fan.
I've owned these for a long time and I never heard of problems with the valve seats. Typical reason for misfires is a bad coil. And what you're pointing at is the Secondary Air Injection System valve, not an EGR, which it doesn't have. It is a high failure system that causes other issues.
I've had to replace both front hub bearings and the blower motor resistor. Replacing the hubs bearings was easier than replacing the thermostat. I had rattles going over bumps and it was because of both front and rear sway bar links being worn out. The hardest job was replacing both power steering lines. Where the lines are held down by rubber or plastic bracket on top of the left fender well, they get rusted out. Trying to bolt the lines onto the steering box is tricky because only a small bolt holds the lines in, and you surely don't want to break that off or you're screwed. Keep checking for leaks
+dukejohnson99 Thanks for the feedback!
The fan clutch problem would have been expensive, but I just rigged it so it was always engaged. Didn't seem to cause any issues. The other issue that seems to be common is the electrical system relating to the taillight. How many trailblazers have you seen with taillights out?
On my 04 with 4.2L it was the rack and pinion steering and both front wheel bearings after those easy fixes this truck has been a dream just over 100,000 miles.
I bought an 06 Trailblazer not long ago. I have replaced the blower motor resistor.
I'm gonna turn the day I bought it if I ever have any of these major problems he was talking about!
I got my 06 Trailblazer in February. I've put on a new set of tires bc the front were bigger than the back, replaced oil pressure sensor and the VVT solenoid. I've got a really good oil leak to track.

Bought my 2005 TrailBlazer four-wheel drive 2 years ago it had 148,000 mi first got it I replaced injector, changed the oil and it was good to go. I'm at 314,492. I drive approximately 170 miles a day. Change oil every 3-4 weeks or 3000 to 4000 miles. Great vehicle! However, I live in Mississippi the roads are terrible! At 175,00 replaced right top control arm. I am picking up another one today, I bought the life time warranty so no charge today. Within the last month ( as time and money allowed) I have replaced both sides upper and lower control arms ball joints, inner and outer tie end rods. I replace my break pads every 4-6 months. I've replaced both back break rotors, and one back break caliber. I have gone through 6 sets of tires and too many patches and plugs to count. I love my truck. Said I would drive it till the wheels fell off. Well, I lied!!!
Right front wheel feel off last month... I put new tie end rods on it and I'm still driving it. God blessed me with this ride!!! Hope it goes another 300,000. I fix everything as soon as it starts s sound.
NOW.. I need help. Have a low hum about a week now. Getting louder and sounds like something is rotating. Several guys at different shops have did the shake test said hub feels fine. I know I still need to replace shocks and sturts. On my to do list next week. Hum reminds me of an old 4x4 Jeep my uncle had that was deer camp ONLY condition. Anyone remember those from late 78- early 80s? 😂
Correction replaced coils not injectors
Clear and concise. Happy to see someone who does it right. I enjoyed the video.
Besides the trans lines and power steering lines needing replaced in the salt belt, and an occasional 14v reference wire that shorts out, you can expect 300k or more from the 4.2 with regular maintenance.
Have 2002 4 wheel drive bought in 2001.

My 5 problems with the TrailBlazer.
1.Moon roof leaks

Past couple of years I've had issue with the Oil Sensor. Driving my 6-cyl 2005 model at 45-55 and then coming to a stop the Oil Pressure gauge will flatline, the engine idle becomes rough, and if I don't manually accelerate the engine the car will stall. I've had my mechanic chase after this one and we've replaced/adjusted everything up to the Oil Pump (sensor, connectors, etc.). There are no issues at all with the engine... no taps, no misses. Mechanic states that the engine appears to not be oil-deprived because it runs so well. It is so random that when vehicle was left for days and driven by mechanic, he was not able to experience it. Just not willing to fork the $$$ to replace oil pump if it's not the real reason for the issue.
Sounds like the trouble I had with my Evap Sensors. Is it worse in the winter or generally cold. And when you fill up your tank do you let the stop and put the hose up or do you keep filling it up afterward to get more fuel in. If so, you definitely clog the Evap at the tank. I had to change that and the one at the engine to make it stop. if you search trailblazer evap in youtube, you'll find a few videos on it.
You forgot the infamous: battery replacement causes air to not come out of vents - always keep power to system when replace battery, or the actuator for the main vents will strip its gears. Known defect, should’ve been a recall.
I had a 2004 Trailblazer. Kept it until 2019. I replaced THREE front wheel bearings. I started to get $100 dollar'd to death with repairs. For a few years there, it was $1000 in repairs per year. And it was a gas hog. Then finally, the car would shut off while I was driving. 1st time was driving 70mph on an interstate. Had to have it towed. It felt electrical. I replaced the ignition switch. Otherwise, car repair place couldn't find the problem. No 'check engine' light. It shut off on me 5 times in 500 yards. (finally made it back home) I tried to drive it to repair shop, got 50 yards away from home and it shut off. Car wouldn't start until the next day. I backed it up to my house, called a junkyard and had them come get it. Trailblazers are notorious for electrical problems and I'm not going to hunt down one on a 15 year old car.
+John Doe Thanks for the feedback!
I've replaced the ignition switch 4 times in my 07, very faulty design in those. But if you order the 2nd gen version of the switch, it holds up far better (with the black and grey colouring on the unit). Changed my water pump and block heater and driver front wheel hub. The passenger front is about to start going soon...and the alternator too. Also thrown a couple of new batteries in it over the years. Since I plunked new plugs in it, the mileage has been way better as well. Mine has 187,000 Km on it and other than a some minor issues, it still runs very well and I live in Canada where the winters beat the hell out of vehicles every year.
They're an ok suv. I have had one of these before. I never had any issues with mine. I dont drive it hard like its a pro street car though. 😂 My only complaint about these suv's would be the god awful unstable steering. (Thats what made me sell the one i had.) They're good and reliable. Dont change lanes fast in them though. The body roll is insane.
I believe the fuel sensor is a recall. The dealer replaced mine for free! It had put me in a hazardous situation.
I have a '03 with over 250,000 miles and I have had all except the fourth issue. The fan clutch, hub bearings I had to change twice but they are easy to do. At the moment I am replacing the transmission. It has taken me over a year to find one that was not over $1000.00. I hope it works. LOL

The power steering lines and transmission cooler and lines!! I've replaced all four calipers as well...
But the main thing i seem to have issues with the most...the issue that seems to come up every year, is the blend doors for hte A/C. Every year, it somehow stops working or gets stuck...or something.

Dash cluster going crazy or the vehicle stalls or both! If you get out and shake the vehicle it will start again? Pull the rear interior panel on the driver side and check the wiring harness that runs along the bottom behind it! It rubs in an area that will ground out the harness! If you're experiencing this issue pull the cup holder out and pull up on the panel you'll see the dash goes back to normal.found that to be an issue on 4 trailblazers with that issue I've worked on.

Maybe just yours champ
Secondary air pump?
The transmissions in these are pretty solid. I've experienced a few that needed solenoids to cure hard shifts, but the transmissions themselves are generally not problematic.
3:05 that is not an egr valve. That is an auxiliary air pump check valve. Because of vvt, this engine doesn’t have an egr valve.

Causes water to leak down onto the engine block and fills the holes were the coil packs sit on top of the spark plugs. The water will eventually leak over time down until the spark plug and rust them out giving you misfires and check engine lights.
You have to replace your hood gasket Plus your coil packs and plugs.
+Joe Lung Thanks for the feedback!
I put a piece of door weatherstrip to deflect water to either side instead of buying GM’s redesign of their original goofy hood seal. How long has this company been building trucks FFS?
I own a 2004 and I can list at least 10 more 😆 all easy fixes
Care to share

How is it man? My cousin used to have one back in the day I was younger now I saw one with 80k miles and thinking to get it its an 02 4.2l
So I have a o4 trailblazer while I'm driving down the road. All dash lights come on , all the gadges drop but the windows won't role down the stereo goes off. . When I turn suv off the security light stays on. Any suggestions
My '04 has several problems but still runs like a champ. Check engine light, shocks needs replaced, my SUV rocks left to right when I take a slow sharp turn and the tires feel like they're slipping while turning slow and sharp. Rear passenger window fell, water or something is getting under my front passenger floor mat keeping it moist and gross. I clean it up..it comes back! And my AC has a leak or something in it. It was professionally serviced 2 years ago and it stopped after getting an oil change at a private shop 🤔
I now watch these video with playback speed on 2.
Per Haynes MANUAL as confidence and experience grows, I can tackle more task

I have a 2002 Chevy Trailblazer with 310,000 on it. I have replaced 3 fuel pumps, exhaust manifold, power steering line-hose, fan clutch, 2 upstream O2 sensors, 1downstream O2 sensor, catalytic converter, water pump, 1 u-joint, 3 sets of spark plugs, 5 coils.
Lots of oil filters, oil, fuel filters, air filters & tires.
I am the second owner, I know them, they took great care of this vehicle. I bought it with 105,000 miles on it.
It still has the original front & rear brakes pads & disks.
This gets used for trips to town, 100 miles, Billings for medical 325 one way. We just bought a 2013 GMC Terrain so the Trailblazer will not be used for trips anymore. I also have a 1969 Chevy C10 with 300,000 on it that is a daily driver. I bought it with 110,000 miles on it.
Keeping up on the maintenance, oil, filters, fluids, tuneups pays off in the long run.
Hello from north east Montana. 10 miles from the Canadian border.
The hard part is finding parts for the Isuzu ascender LS
I keep being informed that i can find them mostly at a salvage yard
I have the blower issue. When I first got my 06, fan setting 5 didn't work. It was fixed and then recently during this winter 4 and 5 stopped working. I got 4 back by banging on the top of the dash.
My climate controls hasn't worked on 5 since i bought my 2005 (lol) in 2019 have no reason too fix it yet I mostly use it on 3-4
Lmao! 5 doesnt work on mine either! I just figured itd be overkill? Lol
Been waiting 8 years for the fuel pump to go out or get weak so I can fix the fuel level sensor inside the tank…not gonna bother until it goes out…just track ur mileage ….ive had every last issue mentioned plus a ton more …wish they had quality after markets to replace these planned obsolescence parts they used so that it’s not always needing another part replaced because it’s been 3 years and the parts are all garbage that wear out fast with minimal use….
I've got a 2oo5 I bought it four yrs ago for 4k...and I've put 55k on it....142k now been a great vehicle....major buy rack and pinion...and a few bearings..😂
Had one, had so many problems. Filed a lemon law suit and won.
Chevrolet junk.
Who did you file against?? The dealer? Chevy Motors??
My problems with my 200,000 mile plus 2004. Fuel pump. That was a real pain in ass, back and knees. Good job putting it on the top of the tank. Bad job not making a access plate to it.
Guess it would have taken $2 to make one and 30 seconds to fasten it down.
The entire dash and modules. Speedo and RPMs are a sometimer. Heat gauge still works. oil pressure still works.
Dash lights nope. Just plugged in a red Led strip and cut piece card board so it would not blind me at night. Now I can see it when the sun is the wrong position in the day time.
The heat works on or off. A/C works the same way. Replaced the module with a fan switch. Locked all the control doors open. The control for the heat a/c still works. Probably because I only use it in two positions.
Note if the cabin was well designed as 1969 suburban. Fan on/off is all you would need anyway. Turn the heat full. Roll down the road. Get to hot turn the fan off. Same with the a/c get too cold turn fan off. As long as you are rolling you got heat or A/C. But why no vents? Guess cables and a flap through a vent system to fresh air was to difficult to engineer. Also don't need a module to replace it.
The rear modules. The control in the rear for the rear window heater and wiper.
The daytime running lights control module. Replace that with a 8 feet of 16 gauge wire to each headlight and two 30 amp relays connected to key on relay in the under hood relay/fuse box.
Front differential bearing. Solution remove the drive shafts. Don't use AWD anyway. Thought it was the front wheel bearings starting to go. Now I got two good used spares.
Anti lock brakes acting up. Removed the 60 amp fuse.
Replaced the power steering rack and front suspension bushings.
Cracked exhaust manifold. Still cracked just use a beer can to cover the burnt out heat shield portion and screw another in it place when needed. It quiets down when the engine warms up anyway.
Rusted out gas filler neck. That was fun. Rusted out spare tire lift safety lock. Rusted out spare tire wheel. Never used. Not been replaced.
And last driver side window control module corrosion. Why put it where the dog can operate it anyway?
Ist noticed not going to fix code? Temperature sensor buried in the oil pan. Makes sense, put it where you have pull the engine to replace it.
So the olde lady does not understand why I won't buy a new cute 2021 with a center distraction screen and a automatic back scratcher.
Guess the 1990-2000 engineering grads went to the Bag of Rocks Engineering University. BUT the EPA, CAFE, and NTSB Engineers also went there on the short bus.
The most important safety and economy operating device is in-between your ears.
I'll bet that you talk alot
My 2002 envoy, NO issues. 250k kms. Runs like new. Every fluid is new.
Well back to watching top 5 problems
My 2002 drains out battery. Apparently headlights turn on overnight on their own and kill the battery. I've taken it to three different mechanics and none where able to fix the problem.
I have a 03 and all I can say is yes
Clutch fan, after changing the clutch fan I still had the same problem. Found out it’s the sensor. The sensor is located behind the alternator. Fun fun fun.
+Frederick Wentz Thanks for the feedback!
