CAR: 1987 260E, automatic 2.6L

Well, the Blower Motor in my car is acting up. It makes lots of noise and just an embarrassment when the passenger is around. Personally I think it can go any moment now. I looked at some units online and saw something about Pollen/Cabin Filter. How do I decide if my car has Pollen/Cabin filter as I haven't opened up the area where the blower motor is?


The vendor says in his ad: "This blower motor fits the following models (as listed below) WITHOUT a pollen/cabin air filter. PLEASE NOTE: THIS BLOWER MOTOR ASSEMBLY WILL NOT REPLACE THE BLOWER MOTOR ON MODELS THAT HAVE A POLLEN/CABIN FILTER."

An 87 260E does not have a pollen filter. The filter was added in 94 (or maybe 93).
Don't leave it too long before replacing the blower if it is very noisy. It could damage the electronic speed control module (expensive) if the blower is drawing excess current or if it seizes up.
You will see this module when you get to the blower. Clean the heat sink fins to give better heat transfer while you are there.
Transmission fluid on the blower motor bushings can extend the life of the blower if the brushes are OK and bushings are not damaged from running too long dry.

Is it a good idea to get a brand new Bosche motor and reuse the squirrel cage fan? Or just bite the bullet and get a brand new Motor+squirell_fan combination? Better to do it once only instead of crawling in there a second time and replace the squirrel cage down the road.

The fans on a W124 blower are very delicate. I have removed them, but made a fixture to use with a small puller. Not easy to do. I would recommend buying with the fans installed. You can buy the Bosch blower with fans at places other than the dealer at a considerable saving.
Others on this forum can give you their opinion and experiences.

Here is what you need.

Mine ('92 300E) lasted no more than 6 weeks from when it made chirping sounds until it seized. Replaced with MB unit that included both "squirrel cages". My original cages looked fine according to my tech, so I guess it depends if you want to change just the motor. However, at 20 yrs old, the plastic on those cages may be brittle. My 2 cents...

Five or six years ago, the blower motor in my 1990 300E got to where it would not run sometimes, and then not at all. I bought a new motor without the cages, intending to reuse the cages. I removed the blower from the car. The shaft was very hard to turn and it was obvious why it would not run. I was not able to remove the cages, so I simply tried putting a few drops of oil on the shafts and turned the shaft by hand to work the oil in. I reinstalled it in the car and it has since worked perfectly for all these years.
