- In this video I have a look at a customers 2005 GMC Envoy that has no low beams. Ends up not being anything to fancy but I at least show you that following a good analytical thought process and plan wins every time!

Where do I get all of my free service info and wiring diagrams you ask? I made a video on that few years ago - czcams.com/video/L1FxoQI_Fw4/video.html
Yes, I did ask!
I used all data DIY to obtain information that was needed during the building of the older 700R4/4L60 and newer 60Es never let anyone tell you you cannot do it in your own shop garage backyard. I saved fortune doing it myself versus paying a shop. And at times I even made money doing it for others. A source of information is imperative.
Many on CZcams use AllData.
@@lvsqcsl And have you checked the price of it? I wouldn't say it's feasible for a DIY'R.
@@billmonroe8826 I believe the price is around 30 bucks or so for an individual car. The price you might have seen is for unlimited cars, which would be appropriate for a shop, but not a DIY'er.
The car owner didn't think it was easy or else he would't have brought it to you. A professional always makes his job look easy. Great video
That's a lie, I call my repair guys and they pick up my vehicle and fix it because I just don't have the time to piss with anything
This video definitely doesn't suck Eric. What a great way to show how to assess if the wiring is good throughout the system quickly and in a smart fashion. Pretty sure the customer is quite happy to only have to deal with a new relay.
I really enjoy these videos.
I have had that happen before on an older car with the 4 lamp square bulbs , it had no headlights. The customer called and wanted me to install a new headlamp switch because it was not working. Lucky for me I checked the system first, well you got it, all four headlamps were burned out!
Spot-on diagnostics, Eric.
That relay looks like it's the solid state type, which would explain the price. Instead of contacts going clicky-click, a transistor goes zappy-zap. Such a relay style should be more reliable, but they're also a common failure item on some imports that use them for the A/C clutch.
Your reaction when you plugged in the fan relay and the lights came on was surprise and a hint of disappointment at the same time, it was great.
Once again, nice video. Can never get tired of watching you logically approach an issue and solve the problem. No matter how mundane it may be for you, it's interesting for us, of course along with your witty comments and real-life advice. Keep'm coming.
The fuse box should be the first place you always start for a problem like this. Assuming you lost both headlights at once....
Hi, Mr. O. Good detective work, again, as usual, as expected. Sometimes the fingerprints match up and the guilty party confesses. Relays that don't relay get relayed to the trash bin. Anyway, thanks for sharing! Stay healthy!
Thanks!
Another good electrical video. Reminds me of my Air Force days tracking down wiring on older F-106 Aircraft radar sets. This was before they had on-board computers to help you. Seems to me there was an F-106 squadron at Griffiss AFB, near Rome (now Griffiss International airport).
PS, never did see that link you mentioned about clear-coating for faded headlight housings.
This is another video where you have taught the masses how to check something that is not overly complex to do. You have again shown as the significance of the humble test light as a versatile and simple tool to use in diagnostics. There is nothing to be sorry about. Thank you Eric.
The average back yard mechanic does not usually have the test equipment that provides them with wiring diagrams for each system in a car. Talk to us about what is available and where you purchase this kind of technology.
@@warrenclement5240 I have a test light, power probe & workshop quality, entry level diagnostic tool with actuation capability. I only bought the diagnostic tool this year. Prior to that I had el-cheapo code readers.
As far as wiring diagrams goes, well Google is your friend, along with forums. The only thing I have not bought is experience gained through having a go. Admittedly I do have a technical trade and have worked in areas where I did a lot of diagnostics and testing with high end test equipment. I am not in the automotive trade.
These days I pay someone to do the work or one of my sons does it. I dabble in diagnostics because I have an interest in that. One of my kids is an apprentice mechanic, My equipment is available for him to use when not at his place of work. I hope he enters the world of diagnostics. Motor vehicles are a complex beast these days. And I love the the comfort they offer. I have a British 4WD, so having an understanding of electronic systems, modules and diagnostics is a must. So far I have had 18 months of trouble free motoring. Prior to that it was a bad case of electronic warfare lol. I trust that answers your question.

Not only is it methodical, you've got the efficient work flow of a guy who has done this kind of diagnostics thousands of times. For example you started on the good light, and quickly checked both ground wires first. Doing so eliminated half the circuit within a few seconds, with a technique that gets electrons moving and exposes any voltage drop that might be present. The power probe is seductive in some ways but it means I need to add the extra step of drop testing. So, I can see why old school methods are so appealing, especially if you're on the side of the road with very few tools.
These are the videos I need Eric. They constantly remind me to have a plan and work the problem. Thanks!
Ty Eric yet another great diagnostic video mate, always interesting watching your thorough procedure in working out the issue.
Keep Safe Keep Strong 🦘🦘🦘🦘
I love your videos that show something I can do in my driveway. Thanks for giving us the confidence to try to fix our cars.
Thank you for making these types of electrical videos. I am not a mechanic but find the process of wire tracing etc. fascinating and educational.
I really do like the way you work things out. It is a lesson of reasoning that I will never forget, just like all your videos. Thank you Eric
It’s nice to see a real working shop where you never know what comes through the door.
I enjoy your videos and appreciate that you take the extra time to make those videos.
There is never a need for a super fancy fix. We love just seeing you do your thing. Just the troubleshooting process teaches us but your personality keeps us. We love getting a video no matter the fix!
We mortals find all of your videos interesting and well worth the time Eric! 👍👍
Nice deductive problem-solving! I enjoyed watching & listening to the thought process. The polished headlamps were a bonus!
It could be a 3 second video or a 3hr video I just can't get enough of them Mr O
You make something that seems hard look easy that's why I like these videos. Great job tracking down problem.
Yep remember those failures. I remember the first one I ran into many years ago. Even if you knew or not you followed a testing process that is excellent and helped your viewers learn instead of just going hey lets swap this and see. As always a great learning resource for up and coming techs or even just the person in their own garage.
Im an apprentice motorcycle mechanic and I learn so much from your electrical diagnostics. Thank you
Honestly this is one of your best simple diagnosis videos.
Eric, I’ve almost caught up on all your past videos. You have been very consistent over many years. Although GRAYER, you always do a great job at both your presentation and editing. Keep up the great job!
Appreciate the new videos. It's also good to reinforce the diag process. Sometimes we get lucky before having to track down a broken wire or rusty ground.
Mr. O, videos like this are my favorite. You show the masses how to properly diagnose a failure. Regardless of the level of the repair, if you have a solid plan, along with decent skills, there is almost no repair that even a novice can't do. Hence, your tag line at the end of every video is very fitting for this video .
This video follows logic so clearly that it could easily be used at any tech school 101. It's clarity helps us understand how to dig a little further had there been the need to. Thank you!
Thanks for taking us along Eric. And I like that you are also cleaning the guys headlamp lenses! 👍💯
That's Eric..always relay some good information and brightening up our day..a polished professional..👍😎🇨🇦
Excellent video. The process to resolution was terrific. Gotta chase two of these electrical issues myself today - airbag and garage door opener on 17 year old Jeep Grand Cherokee. Did find a mouse nest in the engine yesterday when changing valve cover gaskets...
Great logical troubleshoot vid Eric ! Does NOT suck. It's a great refresher on test-lights and reminder to look for a diagram always.
I could care less what you work on... your process is what I am learning from. Thanks Eric. Great work.
You’re a beaut Eric! Keep up the great work. Most of the channels I watch are builds and projects it’s nice to see a confident competent mechanic be able to troubleshoot and diagnose without a parts cannon. I’m a field service tech in the medical field and I see lots of people that can’t diagnose worth a shit.
Like the logic when you look up the circuit diagram and trace it back until you find the issue. It is so logical and easy to understand it is appreciated.
As one who isn't a mechanic, but learns something every time I watch one of your videos, I'll say this video doesn't suck. Might help someone like me down the road some time.
Another great straight diagnosis!! Easy Peasy if you follow the plan!! Thanks Eric!!
excellent teaching video.....for non-mechanic viewers like me its nice to fully follow everything
Your teaching technique is excellent. Describing all your actions and the reason for them. Lecturers could learn from you. Yes a simple diagnosis but the explanation of the process was excellent.
I still enjoy your videos Eric... no matter how long or short... This simple fix you found was NOT what I was thinking was wrong... I was thinking a bad headlight switch, then a broken wire then a blown fuse... you reminded me to always BACK TRACE a wiring problem... Thank again for a great video
I used to follow ScannerDanner but you're much more down to earth. Paul has gotten a bit jaded lately. I like your honesty and your willingness to go the extra mile on some issues. I find it fun and educational watching over your shoulder, do to speak no matter how mundane some of these things turn out to be.
Ahhhhhhh, I remember all so well when headlights were glass (inexpensive) and never turned opaque and yellow.
Cool step by step diagnosis and repair, thanks for the video Mr. O.
Not a crappy video, I don’t know about other viewers but I love your electrical diagnoses videos. I took electrical diagnostic courses when I became a certified Honda and ASE certified tech. I have been out of the automotive field for a little over 10 years now but still work on vehicles on the side and these videos have always helped me not forget electrical diagnoses.
Despite the "simple" fix, your trouble-shooting is well worth the viewers' time. I'm wiring an old Ford Tudor from 6 to 12 volts, every bit of info of how the "big guys" do is good to assist me in my planning. Stay healthy. Best wishes to you, Mrs. O and your family.
Your diagnostic method never fails to impress.
Nicely done Mr. O. Perhaps some might believe that because there wasn't a big "crowd pleaser" reason for the lights not to be shining, this kind of video is incredibly valuable for the world to see when it comes to logic and reason during diagnosis. You perform such a valuable service to those of us who love cars and love fixing them. The things learned in your videos apply to so many other things in life as well. Thanks for all you do Eric.
You deserve an easy one once in a while. Besides...never hurts to review the diagnostic approach even for what turns out to be a simple and quick solution. Thanks for sharing your knowledge.
Great video's Eric O .. As a mechanic i can relate to the daily grind of a shop. Sometimes it's challenging but most of the time boring lol. Keep up the great work 👍
Bro i love watching your videos it is because of you that got into me hanic and study and read books and watch videos everyday only to be hopefully one day like you 🙏🏻🙏🏻🙏🏻 god bless you my friend
Hi Eric, great entertainment as usual. I love the fact that you are probably the only person that was disappointed by the video. Love the methodical approach as always. If it was always a bigger problem to solve it might discourage us DIY folk from having a crack as it would be too daunting
Sometimes you are lucky and sometimes you are smart, and sometimes both. Nice job demonstrating how to follow a logical process.
Thanks Eric! My low beams went out after buying 2 new light housings and light bulbs for my Envoy. Appreciate the logic stepping and your years of expertise. I just wish your shop was near me!
"Diagnosis" thats the word that can't get through most of mechanics mouth xD
Great video Eric
This video does not suck, as you say.
Your use and explanation of logical electrical deduction..very good!
Rock On!
I've replaced the turn signal stock twice on my 2005 buick regal for this exact problem and just figured that's where this video would end... good thing i watched it till the end!
Thank you so much for this, I was having this exact same issue. I however checked the wrong relay instead thinking the one labeled headlamps controlled it. I just switched the fan an control relay and now they worked! Thank you again because I had replaced my multi switch on the steering column thinking that had to be the problem an after that wasn't it I was completely lost
Really enjoy your process. Logical and methodical.
I've come across this year's ago on an 03 envoy, and it also ended up being a 40 dollar relay. Got an 07 envoy now and it has been a joy to own. Tough truck.
Another great video. To paraphrase you tag expression .If you can do it so can I. You give us backyard mechanics confidence and tips to trouble shoot ourselves. If the problem is greater than our skills can handle, that's when we should pass it on to the pro's.
Definitely a damn good video love the way to logically go through and figure this out I don't think it sucked I thought it was still very good video on how you figure things out and do diagnostics love it keep it up thank you
Great video Eric! Some of the equipment I work on daily has 60+ relays. Depending on the function they can be a real bear to chase down and to make things worse, it's German made with German diagrams...I only know English. Some days are challenging. Thanks for all the great videos!
Dude, this is a perfect video, mostly because it goes to show that sometimes the issue isn’t always some crazy insane failure. I’m sure the customer was super pumped it was so straightforward, and everyone is happy! Thanks for sharing the easier ones, genuinely!
I fell into the trap of "it just needs two bulbs" once. I had a '68 Ford Galaxie 500 convertible that I was restoring, and the brake lights didn't work. Did I even check the bulbs? Nope. I just assumed "old car, bad wiring." I started at the brake pedal (at first I assumed it was the brake-light switch, but it wasn't). I worked my way back, following the wiring harness from there. Everything tested good, all the way down. Then I finally checked the bulbs. LOL! Felt *REALLY* stupid, but learned a good lesson -- *ALWAYS* check the simple stuff first! 🙂
Great video and explanation. We solved our Envoy headlight issue following your steps.
Excellent troubleshooting Mr. Holmes lol. Thank you for the link on troubleshooting subscriptions! Makes life so much easier for the backyard mechanic. My son was hit by another car causing a minor fender bender. Ruining his rear d.s. taillight Amazon 200, ebay 140. Local pick your own parts 26$!!! SCOOOOOOOOORRREEEE!!
Exactly what I expected it to be. Had a 05 Grand Prix. Mini relay. Took a quick crap. It's actually a recall on those. Thanks for sharing.
The Humdrum, the mundane, the everyday and I'm still here watching till the end. Thanks for the video and I'll see you next time!
Very excited. This is the earliest to a SMA video ever 🥰
Well I for one thought this was a great video. Good mechanic and good teacher, what more could I ask for.
Thank you for the easy to follow instructions! I appreciate it, my low beams have been out for about a week😅was gonna have the shop look at it tomorrow but may look at it myself tonight.
Checked to see if the relay was bad and it was, very quick and simple fix☺️
Got to love those easy fixes. Enjoy watching your channel.
Another fine video. I wish I knew some of this stuff when I was younger as it would have saved me time and headaches.
Classic fault finding protocol. This is where many shops fail, by using `common knowledge', rather than a fact based logical method. Nice touch to shine up his lamp covers. Thanks so much for the link, this is VERY useful
Thanks for the tip! I swapped out 45 and 46 to check and had lights again!
SURPRISE--SURPRISE Got an"easy" one,but had some real logic to get it done.. GOOD JOB, AS USUAL...You are the man...
Your powers of deduction leave little undone. Nicely worked out.
great video Eric .... love to watch your logical approach.... thanks for my lunch time entertainment
Good morning Eric! Have an awesome week !
Good advice Eric, never overlook the bulbs blowing simultaneously. On my 2001 GM Holden Commodore, the cruise control stopped working, it would make a clack noise when turning the key and it wouldn't respond to any inputs. Long story short, some testing and trawling through forum posts later, I found out that when the brake light circuit has a fault, the cruise control stops working. I checked my brake lights, the one on the spoiler was working, but the bulbs were dead. I put a test light on both the bulb sockets while I used a broomstick to depress the brake, and both had power. It was only then I took a closer look at the actual bulbs. Turns out both bulbs just blew at the same time. And to think I was nearly going to pull the trigger on a new cruise module.
To my credit, I was far less experienced back then several years ago, I never considered the possibility of both bulbs blowing at once.
Yep, especially if you replace them both at the same time. Discovered that with headlights about 4 years ago, if memory serves, the driver's side went, and had not gotten to the parts store to replace it yet as I was not needing to go where they were at the time, 2 weeks or so later, the other side went, so had NO low beams (I did have separate high an low beam lamps in my car), so had to buy both.
Often overlooked is there are two parts to learning. The details/knowledge and how to think and use that knowledge. This video was pretty basic on the knowledge side but a nice clean demonstration of how to track down using logic instead of guessing. The use of logic is what you have to train, using simple problems, so that you have the discipline to be able to dig into the complex ones.
You did a great job describing your process in this video
I have a 2009 Chevy Trailblazer and have had that relay go out once. I kinda figured you knew what was wrong at the beginning of the video. Apparently it’s a common issue with the Envoys and Trailblazers. Great troubleshooting!
I love these quick videos. I had the same issue with a 2009 envoy. turns out that is not a mechanical relay. Its a Mosfet transistor driver so the BCM can PWM the "relay" for the DRL.
Definitely NOT a bad vidya! Nice to see you after a 12 hour day plus 2.5 hrs commuting! Keep up the good work!
i saw the title and and knew it was the relay i just fixed one of these yesterday same ting the video dosent suck and video you put out is awesome!!
This is a simple DIY fix only if you know where to start. Thanks for sharing. A few years ago it was just power, switch, fuse, and headlight in some order. No body control computer. It was easier back then.
I chuckled when you called the cops "the fuzz". A term we used in my much younger days!
Nice way to start my day. Thanks Eric!
Keep it simple and methodical. great video Eric
This was a great video, the logic of the simple fixes count too, thanks 👍😁
Thanks Eric, another great video!
Good video, good refresher. Retired this past January. Have not had the need to drive the commuter car at night. I do drive with my low beams on all the time. The nicer newer car was out of town. Had dinner and a drink at the local tavern, a dbl Jameson and a Carnivore Calzone, leaving just after dark in the commuter and no low beams. High beams work fine. Before you take anything apart put the spare bulb in the connector, worked fine. Lucky for me it was just the bulbs, both were burnt out on the low beams. Things you don't notice in the sunshine. I felt bad about driving home on the high beams, but I was not flashed once. I think the LED bulbs throw so much light that high beams on an 06 just look like low beams now.
If they could always be this easy!!!!! Hello to the lovely Mrs O !!!!
This is too funny! I have a 2006 Envoy and this exact same problem just happened to me last week.
There is a recall for this exact problem! I have kept throwing the recall reminder I get every so often in the mail for the last several years away.
I found out how much that relay is, I'll now be reinstalling the bad relay and bringing it in to have the recall addressed.
As always a great video!
TSB isn't a recall. won't you have to pay there ?
GM reimbursed me for cost of new relay from AutoZone or O'Reilly's. It was about $30 at that time, quite a few years ago.
@@davecaselli1957 Your right. Thank you. I replaced TSB with recall.
Top deductive reasoning…..I recall that post of yours when you polished up the lenses ages ago!👍
Watching you easily remove that headlight housing reminded me of my buddy and his 2001 F150 years back. He’d bought it used in another jurisdiction and on the long drive back home realized he had a driver side headlight burnt out. When I saw it after he got home the entire front was torn apart from him trying to get at the headlight bulb, there was a pile of assorted bits and pieces in the cab that he’d removed in his efforts. I went over to the passenger side and pulled the two little tabs up and pulled the headlight housing out in seconds and watched his jaw just about hit the floor!
If your diagnostic procedure is accurate, then the fix will be as short as possible. Excellent example! Great show.
Nice job Mr O! I would have taken forever to even think about the relay!
Thanks for being a great teacher sir
