Video still coming in handy 7 year later. Thanks man, I’m much warmer now!
That’s all that matters 🙏 Good to hear . 😁
Wanted to say thanks. Mine flooded when drain plug blocked and rain entered. Heated didnt work at all. This gave me the confidence to dismantle, dry and reassemble. Works as good as new now!
Great to hear!
Thanks for this video, its the only one I could find. Didn't realize the heater fan was so accessible. Last time I had to change one was in my 1982 TVR 350i and that meant the whole dash had to come out.....
Anyway; after getting to the fan motor, removing all the dead leaves and trying to coax the motor back to life....yep I also forgot to plug it back in......But when I did plug it back in and ignition on, still no joy. I tried pushing the spindle like you did but still no joy so I went and got the mechanic's best friend, yes I beat it (gently) with a hammer and now it works... woho 😎
Same procedure worked for me thx...
Thanks for sharing the heater fan quick fix, it worked a treat on my W202.
Thanks for this video, it helped me out! At least I found the problem(brushes) and saved me some time and money wasting. Many thanks
very welcome
Very Awesome Video, took about 10 minutes and blower is working great!!! Many Thanks
excellent :)
I like your videos. I have a Porsche 928 and there are people like you on the forum that keep our cars going. I used all your videos and imparting of knowledge to replace the whole front end in the 99' W202 I bought my daughter. Looking for a video of yours on timing chain replacement right now.
Unfortunately I have none on timing chain replacement .. I haven't had the need to do one yet ..
how about tracking down a strange wiper condition. I have replaced the motor, both relays and the combo switch on steering column. I have also refreshed all the wiring harness grounds I could reach behind instrument cluster and under the hood. I am still having intermittent wiper control issues. Won't shut off sometimes, acts like it is just turned on. I am feeling it could be a SAM issue. Thoughts? I have ordered a true diagnostic tester (Hain@ Mercedes Benz Carsoft 7.4) rather than just an ODB scanner.
year make and model.. do you have rain sensing wipers ?
I have a 1999 C280 without rain sensing wipers.
No rain sensor issue then, that would be the last on the list to test , so yeah a SAM or convenience module issue is likely.
really great vid- do more...you are clear and concise...
Hey thanks for posting this video. I did as you showed and the temporary fix worked. New motor on the way.
+paul kupernik by the way its -1 degrees F here lol
+paul kupernik excellent :) -40f here Sat night ...coldest I have ever seen
Thanks Fupa! Another informative video. I have a 97 C230 and always check your videos first when I have an issue!
Thank you very much
I did not know it was so easy
Saves me money
Greetings from the netherlands
Glad it helped!
No fan yesterday in m W208 CLK430, temperature outside is minus stoopid cold. I will try this and hope it helps. Thank you for the video!
Thank you very much, the fan on my 1997 W202 will not start up 99% of the time, I will do that trick
Thank you sir. I just fix my blower with your solution . Hope will last a few monts. Thanks a lot.
fingers crossed
Thanks. Worked like a charm.
Glad to hear it . Winter is the worst time for the fan to stop 👍
Nice sharing my friend
Thanks a million for this video! Got my father's old W202 and the blower doesnt work. Hopefully i can find out why after getting mine opened, just had to know where to look and how to take it off.
My blower motor on my 98 clk320 died about 2 months ago and i called an auto wreckers in the GTA and got a used one for $90 with the resistor. When i removed the old one i hooked up the fan w/o the resistor to an external battery & it worked. So in my case the resistor was shot but thankfully the used one i got came with the fan and resitor. This an extremely common problem with w208 and older models. I know 2 other w208 owners had had to get new blower motors. The dealership charges like $350 for the fan only and another $2-300 for the resistor, which is absurd. I got the whole thing used for $90.
Mitch Rubin yup, a used one is the way to go, and they all eventually die ... this was just to warm my ass on the way to getting the used fan :)
Thanks for the effort in making this video...I see is very cold!
That's a gangster ass hat
thanks!
I could have gotten at least a year out of the old one if I had seen this video before I ordered! Oh well new parts is new parts. Got the right center tempering vent actuator in too...just enough room with the glovebox and pass upper removed. Lets see...calipers rotors and headlights? Ty as always
+William Z I thought you had seen this one... damn, sorry
No problem its all good.. heres a new one for you. I installed LED dome lights and am wondering what the value of the load resistor should be to allow the car to sense that there are lights in the fixture so that the single passenger side spot can work? I figure that the car thinks that there arent bulbs in it so they all turn on when the single spot switch is pressed
William Z Hmm not sure on that.. never had an issue with any of the LEDs I put in. Electricity stuff makes my brain turn fuzzy
Great fix. Thanks!
Nice one Fupabox. Love the hat. A word from the wise told me never to run the fan at full blast as it's a sure fire way to wear it out; never mind the noise like a 747 landing on your roof!
yeah I tend to leave mine on auto.. rarely ever goes to highest speed...not sure if it would wear quicker, but it is very possible due to the lift on the motor shaft at higher speeds
Yea, heaters are a bugger to replace on most cars. One whitty car journalist wrote about his experience replacing the heater motor in his Mk III Ford Capri.
He was of the opinion that Ford hung the heater on a piece of string in the factory and then built the rest of the car around it…….!
del boy I sold an old Volvo 240 wagon years ago because the heater fan died... 10 hours to remove the entire dash to replace.. I decided it was time for a new car :)
***** Hey, you love it really. All those scars on your hands are testament to your dedication to not letting any car beat you.
Thank you
Do you have a video with the coolant auxiliary fan noting working for C280. The fans do turn on when I push 12 volts into the connecter plugs. Any suggestions
likely the resistor for the cooling fans or a relay . you can swap a relay from one of the known good circuits and see if the fans now work . If not the resistor is located near the bottom of the rad on the drivers side ( depending on which model you have ) .you can trace the wiring from the cooling fans right into the resistor . I don't have a vid for it , but it's not too hard to check the involved components. You have eliminated the fans , so they aren't the problem , So it's down to either negative power not getting to the fans through the resistor , or positive not getting through due to bad fuse or relay . Does your a/c heater blower inside the car work properly ? sometimes the cabin heater blower can halt function of the cooling fans , but generally not .
@@fupabox i have a 1998 Mercedes C280 V6 non sport US model. A/C heater blower inside works properly even the defroster every morning here in California, except my A/C cold air because my compressor seized/broken. I've changed a couple bad fuses so next is checking the resistor/resistor ground (assuming its under the driver side fuse box and not the driver side fuse/relay box inside the engine) and the relay. Follow up in the AM.
I have a 2006 C180 W203. the ac fan speed keeps fluctuating regardless of the speed setting I use. Have checked the blower fan regulator, and even changed the ac control panel in the dash board. No change. any ideas on how to fix this? should I do a AC reset?
My fan ( in my C250TD) sounds funny when running with higher speed- some squeaky noise- maybe some oiling would do the trick, but don't know exactly where to oil it- any suggestions?
Anyway- Thanks for the video, man.
Thanks ! Was what i need.
I did it and it worked
+Terez Borbely excellent :)
Hi Fupabox,- 2001 CLK320
My blower motor wasn’t working. I pulled it, one brush wasn’t making contact, I jerryrigged it, put it back in. It works. However, it won’t turn off, even when I turn the car off. I’m assuming the blower resistor is bad? Your thoughts?
likely the resistor or the fan control relay . Check the relay first under the hood (remove fusebox cover the unscrew the top ... has to come off to get to relays in back) cant recall which one is fan relay ,but it should be located in there
fupabox thanks, it was the resistor. Curious if you knew why the lcd screen is not displaying all of the functions.. some pop in and out.. for example: the first three bars of the fan power are not showing, and the “smog” is always showing
@@mattnota1284 likely the hvac control unit is failing. Smog is activated by pressing and holding the recirc button for a few seconds . If it doesn't reset by pressing recirc . then something in the control unit isn't working properly. I know there are places that can fix older digital hvac control units but not sure if they are worth the $$ over a good used one
mine done the same thing but it was rust at the same place were you touch when i open the plastic part to reach the fan it was full of water so was rust blocking the fan W-40 and silicone running again I cannot see where the water coming from have an idea ??? I know it is were the wiper rest because the snow melt in the night the car was in the garage
the drain tubes from the base of the windshield where the air comes in are likely blocked up with leaves and dirt. ..poking a coat hanger down them will clear them out
@@fupabox Thank you very much for the answer.. I will do it ..but will wait for little bit of heat now it is -21 with the wind
Fupa, thank you! I checked using the pushing on the motor shaft and is the fan motor. Unfortunately could not adjust the tension on the brushes.
Do you have a video on replacing the fan motor.
I looked on the FCP web site and they have prices from $200+ to $93. for the fan. Is there a brand that you use?
Also do you have a video on testing and replacing module under the seat?
Again apologies for late reply .. haven't been home is a few days..I have always gotten good used fans from the wrecking yard, so have never purchased a new or aftermarket one. about the under seat module..do you mean the power seat control module ?
oops forgot the fan motor question... no video.. it's only 3 torx screws holding it in and the wire plug. you need an Ohm meter to test the resistor.. it just varies the resistance across the negative side of the wiring
The one you mentioned that could have bad solder joints that needed to be checked after checking the fuses when the seats quit working.
so if the fan is making that ticking noise, it is dieing?
thank you for this video by the way, my old clks fan seemed to die when it got very cold out. 99 with 145k on it
The ticking could be something stuck in the fan from a plugged cabin air filter
***** you sir... are correct! I had a hunch it was something but I also began to accept it was dieing since the car is old.
But upon removal of the blower, a lonely largeish leaf made itself a home there!
Removed it, and put it all back in.
Silence!
But I do plan on replacing the blower next month due to its age.
Yol Yeah , they will all need replacing eventually, best to know it won't konk out on you in the middle of winter :)
That really must have sucked Fupabox....would've been freezing my little California ass off.
LOL.. it wasn't that bad.. fixed in 15 minutes..thank god it wasn't an older Benz with the under hood hamster wheel blower...they take a while to get out :)
Hey if it starts up but the middle vents are not working but that sides ones are. What could be the problem?
depends which model Benz you have .. some the center vents only blow cold air with the a/c on, some will blow only a bit warm down to cold , and some will blow any temperature. If they won't blow at all , it is likely a stuck or broken flap actuator.. what year and model is your car
Thank you!
Hey man PLEEEAASSEE can you help me on something quick, my fan is working 100% but my c230 is not generating any hot air no matter what I crank the temperature up to :( Please are you able to advise me on what the problem could be. Many thanks.
likely the duo valve czcams.com/video/8jhPEfLI45s/video.html
do you have a video on how to replace the motor and where to order it?
you can get one on ebay or a wrecking yard...or "rockauto" replacement is simply 3 torx screws and unplug the motor
Wish you had done a "complete" diagnosis/blower change out video... TOO LATE, you sold the 208. :(
im guessing this is the same fan for the cold air right ?
live in the gulf :P hot air ^^ and by -10 you mean celsius right ??
anyways thanks for the info again ^^
yup..same fan for a/c and heat... and yes Celsius. How are you doing ? Hows the r170.. my friend just bought a 1999 slk 230, so I guess I'll be under the hood on it soon :)
***** im doing just fine man thanks for asking . as for the thing we talked about before well i guess that im f*cked :P im not going anywhere anytime soon ^^ other than that im doing fine :> and the R170 well i haven't have time/money to fix what was wrong with it before BUT nothing broke since so thats a plus :P but i think the gas pump is going soon as some times when i started up the engine just rotate with no vibration or cranking sound until restart it again and it just fires right up the 2cd time ^^ that or its the K40 needing some love ^^ and ya the only heat source that i have in that car is the seat warmers as i think that i have a water leak in my evaporator and i DO NOT want to think about fixing that :P + i live were the COLDEST its ever been is 0 and i dont think we are getting 0 this year ^^ i heard of -10 but thats far in the desert area where no one lives :P
KingStivan Saved by heated seats :)
Nice!!!
when you going to work on the cb400?
***** lol when my son moves his friend's bike out of my garage ..it's in 1000 pieces and boxes , and taking up all my free space... grrrr . :(
your the best :D
it appears my problem is the fan speed resistor pack, after removing the fan and cleaning all the debris and dead wet soggy decaying leaves out of the motor, the tray below the motor and the air filter, I cleaned up the motor WD40'd it and put it across a car battery and it spun super fast - put everything back together and no go, so I'm guessing its that resistor pack on the heat sink next to the motor - which can be found in this video,
czcams.com/video/GRiq-U13T68/video.html
yup. The resistor is generally the problem if the fan will work with 12v applied.
bruh least pull the seat all the way back and fix phone on car floor with something. like come on xd
This is a terrible blurred video
