Mercedes W124 - Replacing the blower motor - Tempmatik HVAC

On the 1990 model with no cabin air filters.

[@nourfaheem3688]

Extremely detailed and helpful! Thank you for your effort!

[@bsclifton]

LOL - love the wiper motor test at the end. Great video! 🙂👍

You go, Bro!! Lots of love, dedication and elbow grease!! From Lisbon, EU. With Love for W 201/124. Keep up the good work on the Mercedes-Benz. 😉

[@ryanmundt9628]

Thanks for this tutorial. I didn’t even think to check for a cabin filter version. Fingers crossed I got the right one.

[@mqnwest]

Your videos are exceptional. "Who the hell do you think this is?" Love it!

[@terran5569]

Thanks! This was a very satisfying project.

[@tintblack6327]

great video i inherited a 1990 w124 that sat for 4 years and the previous owner replaced the blower motor. but sitting for 4 years there were squirrels and mice all over inside and it the vents making nests in ironically the squirrel cage.. so i pulled the "new" motor and put a working motor back in. which was the old one and now i know why it was replaced to begin with. i too may see if it can breathe under water. you have earned my thumbs up and sub.

[@CarswithNash]

That’s a decent amount of work to get to that! Great video though, I will have to watch it again when I tackle this on my car.

[@MasiJohn5734]

amazing video love the process love the work love the passion

I love the reklamówki. ❤❤❤

Good DIY video, very helpful, thanks.

[@redpurple1035]

yo CCNA Engineer. that was a brilliant job with the motor replacement. 😎

[@clickireland1113]

Hello MM; Will email you about the pods tomorrow. Today I was just at what this video shows and got rained off. So thanks for the video, tomorrow is going to be easier after seeing this. I want to get the whole black plastic airflow box (german translation) out of the car and removing the blower motor seemed like a good step. If my lower wiper motor rubber is ok I'll post that too by the way. And the wee screws if there are any on my yoke. PS Rain is small drops of wet that fall from the sky

[@eternalbeing3339]

Thank you for the detailed tutorial.

[@OrnumCR]

Yep, did this job on a W201 not long after I moved from WA to Victoria and brought the car with me. I think it was simpler on the W201 from memory…hopefully I won’t need to do it on the 300CE C124 I have awaiting some love and resurrection…but it more than likely will need it too.

[@MMWA-DAVE]

reckon it will soon enough if not already. I need a second one for my blueblack 124 as that motor squeaks now too

[@AlwaysBored123]

Dilinizi bilmiyor olmama rağmen süper harika bir anlatım elinize emeğinize sağlık teşekkür ederim.

[@P.Galore]

Excellent video. You probably don't need to remove the fan bracket...old should fit new....I find it useful to take pictures of everything in the process in case I have a senior moment putting stuff back in.

[@MMWA-DAVE]

ill let you in on a secret - thats half the reason i started videoing everything 😂

[@mercedeske]

My, next task on the list. The blower motor is out, washed and lubricated. I will find out if it's worth the effort but I am pretty positive that I will have to buy the new one, same thing as you.

[@MMWA-DAVE]

yeah made it quiet for a while. My blower motor had nearly no brush material left too. Doesnt look like its easy to change them but probably not impossible

[@rboeken6376]

I did this for my R129, almost identical job, I of course broke some 24 year old plastic that sits underneath the wiper arm but apart and also broke one of the vacuum connectors, eBay to the rescue, also a good time to lube the wiper motor

[@MMWA-DAVE]

cant remember if i mentioned that but yes 1000% agree its a good idea to clean and lube the monowiper. I have already done it on this car so probably forgot to mention it.

[@johnhopkins6260]

Excellent, detailed video!! 👍👍 For the next viewer, while everything is opened up, would someone please measure, and post, the max current draw? connected directly to battery, i.e. max speed. Next: the "electronic speed control" (under the blower motor 🤬 ) failed... most likely due to dried out heat sink paste... causing poor transistor cooling to the "igel" heat sink... then failure... of course at the beginning of freezing temperatures season. Why M-B decided to bury this transistor under the blower... vs. in the top pf the blower housing... (but I ain't no genius en-ge- neer)

شرح واضح شكرا

[@user-wj7pu6kl5v]

Greetings, on my 300e-24 there was the same problem with the whistling motor of the stove. I just took it off and lubricated the bushing with engine oil and it stopped whistling! The bushing of the motor is made of brass and it is porous, the whistle from the fact that the lubricant ends. The mileage at the time of lubrication was 137t.km.

[@MMWA-DAVE]

yeah i did this a couple years ago, it will come back. Also theres near no brush material left on this motor so its end of life anyway.

[@jameschrysanthou9146]

Hey, great video once again. This channel is a massive help for my 300ce-24 restoration. Do you think you would ever be able to put a clip together showing an overview of all the vacuum lines in the engine bay? The previous owner seems to have just reconnected everything to a random fitting, I am struggling to piece it back together.

[@MMWA-DAVE]

on the engine itself theres not that many anyway or are you dealing with the entire engine bay thats been messed up?

[@jameschrysanthou9146]

@@MMWA-DAVE unfortunately it's the entire engine bay, when I got the car most of the lines had been cut by the yellow valves, and any that are connected to the intake manifold look suspicious and tampered with 😬I have some not connected at all by the charcoal vapour canister side

[@MMWA-DAVE]

@@jameschrysanthou9146 go in my about page and find my email. Send me an email and ill send photos of the engine bay tomorrow. Wouldn’t be worth making a video about that as hardly anyone would be interested 😉

[@azamkb]

@@MMWA-DAVE You joking, mate? I, for one is very interested to have info about this. Mine is a 260E

Beautiful

[@chadichadi7658]

Hi , I loved the video and today I went through the same process. Any chance you share the link where purchase the new blower motor please .

[@N2020el]

Muy bien vídeo.....genial....he hecho lo que enseñas pero mi ventilador si le doy corriente directamente desde después del fusible funciona,al mando de ruleta selector de velocidad del ventilador no le llega 12v...sabes si existe algo intermedio entre el fusible y el mando selector de velocidades?algún relé o algo similar?entiendo que después del mando va a las resistencias del ventilador que en mi caso es una cajita de metal perforada con círculos y de ahí al ventilador...todo tengo bien hasta el fusible.....algun consejo?muchísimas gracias y ya tienes otro subscrito y otro like!!

[@tony66au]

LOL....... Sooooo another good reason to replace a worn fan motor is the extra current it draws as it ages that can kill electronic modules in the HVAC system.

[@MMWA-DAVE]

yeah, this version is just a old fashioned 4 way switch with a coil resistor block. They do end up melting the fuse box though, particularly with the cost reduced later version fuse box, which ends up doing this anyway if used on high often.

[@kerimkerimov404]

hi did you get those air shocks new?

[@sokolskenderaj9690]

Done this two times on my W124 .

[@meporfo66]

Easy Job👍👍

[@shaazy]

Awesome video as always. So I just had the blower replaced by a shop and AC recharged. It blows cold but I remember it used to blow colder. I suspect my recirculation button isn't working so I watched this video to see where the fresh air opening is to seal it off with tape, is it visible in the video? If possible, can you point me to it? Thank you!

[@MMWA-DAVE]

the usual issue with the recirc flap isnt the flap but the vacuum pods that move it. They puncture and no longer hold vacuum. Normally open is the resting state without vacuum. This is a dash out job to fix and depending on what version you have, the pods are no longer available anyway. They can be rebuilt though very fiddly.

[@shaazy]

@@MMWA-DAVE oh yes it's quite a pig of a job to repair those pods. So I wanted to tape up any fresh air openings manually till I work up the courage to fix them. However, I just went under the blower to try and manually close the fresh air opening. I saw the flap and it's resting in a closed position, same as i see in this video. Is this the fresh air ON position or OFF? Strange that I'm getting fresh air with the flap like that.

[@MMWA-DAVE]

@@shaazy To be honest, its been so long since I worked in that area I cant remember what it looks like. You might need to seek advice on the w124 enthusiast group on facebook (though the quality of replies ranges from gold to absolute garbage 😂 )

[@aliem.1448]

I bought a pollen filter that my parts supplier told me would fit my 300E24. I was surprised nothing was there after removing all the plastic stuff under the wiper. Neither does yours. I think it is a shame...

[@MMWA-DAVE]

these filters only came on the later cars, 1993 or 1994 onwards is in my mind for some reason. And yes it is terrible that there is no filtration, its disgusting the garbage that collects in there that we breath in

[@aliem.1448]

@@MMWA-DAVE I’m going to look for a way to retrofit. Maybe installing the blower box out of a 94+ wrecker. Or just putting some thin sheet filter under the air intake or something

[@MMWA-DAVE]

@@aliem.1448 changing over the airbox is a massive job, i would look to install some filter material to the underside of the inlet screens

[@rachidrachid3909]

Merci pour cette vidéo

[@sophiathe380sl]

Great video! Did you buy your blue coat from Kent at Mercedessource? 😂

[@MMWA-DAVE]

haha, never bought anything from him before, the shipping cost to AU is outrageous. This blue coat i just bought on ebay, probably comes from same factory in China, just havent had it embroidered with MB star.

[@sophiathe380sl]

@@MMWA-DAVE goes great with your sandals and sarcastic comments.

[@turkoven7513]

Really thanks..

[@nehuge]

My new one (forgot brand) sort of squeals at low speeds and as speeds increase it shuts up. Any idea?

[@MMWA-DAVE]

if its from the bushes id give them a few drops of oil. If its the brushes - no idea, maybe will quiet with more use.

[@JimboGaming]

How much the cost for the new blower motor dude? my car is 1995 E320

[@MMWA-DAVE]

Yours is different to mine - you would have to find the correct part number for your car. Don’t order my part number for your late version car as the fans are different sizes without and with cabin filters.

[@JimboGaming]

@@MMWA-DAVE indeed E320 came with cabin air filter, btw thanks for the advice&info dude 🙏

[@josse5173]

Hi, I got a W124 260E from 1988. How do I find out if my car have Automatic air conditioner or Tempmatik? I got the same controlpanal as you?

[@MMWA-DAVE]

if it looks like mine its tempmatik. The automatic climate control only has 1 temp wheel and push buttons for air distribution and fan speed control

[@richardgreene3460]

Just did the blower motor on my 1994 E320 wagon. What an ordeal compared to my W123, W126, W210, W220 and W221 cars! WHY did MB design the car this way? I guess they learned with the W210 that followed (and went back to the simple W123/W126)!

[@MMWA-DAVE]

the w114/115/R107 AC version design is the worst i’ve seen with needing the entire dash to be removed. w124 isnt too bad, it would be quicker if not recording everything like i did. I spent probably half the day on this job and in reality its probably about an hours job with all tools organised.

[@mr.chimeziennadi6852]

How much for new fan blower because mine is bad

[@MMWA-DAVE]

if yours is exact same airconditioning type as mine without cabin filters - you will have to search the part number shown in the start of the video. I dont sell anything only show what i'm doing on my own car.

[@mr.chimeziennadi6852]

@@MMWA-DAVE thank you but, can you give me a link or contact where I can buy it.

For my model i need to take off all the board/panel to change. I like to do some basic work on my work but i also know when sth is too much for my skills. Local shop cost ridiculous money/hour so unfortunately although i loved it this isnt the right car for me:/
