Anybody have the pictures and instructions for the blower install? It should be in the DYI section! It is such a common issue for us w124 people.

I received the materials from Viper300E and replaced the blower motor a couple weeks ago. Followed the written instructions and took pictures along the way. My pictures are not the greatest, but I guess they help to get the point across. I also have a few amplifying remarks to make the instruction set clearer.

Hopefully I can find time to put this together this weekend and post a link.

The hardest part of the job for me was the removal of the "squirrel cage" fans on either side of the old motor and installing them on the new motor. No way you're going to do that by hand. I had to bend a special fixture out of bar steel and use a 12-ton shop press.

The actual disassembly and access to the blower motor is simple and can be done with normal hand tools. But you will be better off with some tips on exactly how things come apart so you don't break anything.

The car sure is more of a pleasure to drive now........

Ken, didn't get the chance to R&R my blower motor. Would love getting the info you have from the material I sent you, especially the pictures! I bought the motor with the new cages, I suppose that will be easier?
Talk to you soon!

Sorry for the broken link guys! I had to change internet accounts and I just got around to putting the site back up.

Man I would love to get that kind of info on my 126.

I am unable to open the web page with your photos, can you re establish them.
My blower motor occasionally gets squeaky, maybe only needs a little lubrication but I don't know where to begin to look to find access to it.
Any help will be appreciated.

Link not active, please repost. I could really use the info.

Thanks

I want to thank you for the great info. My blower motor wasn't working so I followed the steps outlined. I was surprised to find my cabin air filters completely filthy. Just to make sure the motor would turn, I gave it a spin and then turned on the power. The blower worked. Since I had gone that far I decided to change it anyway, since I didn't want to do this twice. My biggest problem was getting the weatherstrip to stay against the bottom of the windshield afterwards. With this kind of help available, I will be able to keep up with the demands of a 14 year old car and not spend my retirement money. Anybody need a used blower with fan?
thanks!

Do not throw it away. The only thing thast wears out are the brushes. Clean it and change the brushes if they are worn. It is then "rebuilt."

I think it is known as a blower motor regulator, it is electronic and not a simple resistor array.

I think I have a good used one.

is this blower motor in the same spot on the w202 model's aswell? or is it near the cabin filter on the passenger side of the car? my car's having blower motor problems as well. But I've noticed on my car if u start banging on the bottom side of the passenger area the vents start blowing air temporarily. let me know if u have any knowledge of these issues with the w202. Thanks!

Well, I just completed my second blower motor repair at 270K miles. I think the 1st was at about 150K so this one didn't last quite as long. The first one was a regulator which I replaced and did the brushes at the same time. This one was the motor and the brushes were still good, so I just picked up a used motor from ebay. The replacement motor was fine but one of the squirrel cages was was very out of true, so I pulled that one off and replaced it with one from the original motor. I made a little puller out of stuff I had laying around and I'll photograph it and post it here. I swore when I did the first R&R that I'd sell the car before I did it again, but this time was easier with the great photos. Helped my memory. Now I have heat and defrost again - woohoo!!
Thanks for the great DIY post. -RZ

JSlabotsky, you're a genius. You just saved me a bundle of money! My mechanic diagnosed my Blower Regulator as the problem, but when I pulled the motor, I decided to bench test it. When I found it was bad, I took it back to my mechanic (who's a great guy btw) and he confirmed. He felt bad that he misdiagnosed me, so he sold me a used motor with cages for $40 bucks. (deal) While I had everything taken apart, I cleaned the whole thing. Went back easy too.

I'm adding a couple of pictures I took with my phone... I added some arrows and text. Hopefully they'll help others.

Anyway, if you're ever in Santa Cruz, CA, let me buy you a beer!
