Blower motor squeal
Recently a sqeal has developed in my 124 300D 2.5 turbo. It sounds like it is comming from inside the dash. These are the conditions:
Climate control on low - intermittant squeal CC on high - No squeal A/C on low - intermittent squeal A/C on high - No squeal CC off no squeal It sounds like a loose belt. Is there a belt driving the motor? How to fix?

The blower motor bearings are probably dry. Either replace the blower motor or take the thing apart and lubricate the motor bearings.

It would be a DIY for me, but I have no idea of what your skill and tool set include. Nothing too difficult, just time consuming, and some mechanical apptitude required.
You are right about photons and quarks, just one level lower than electrons.

If I were a photon or quark, I could access the blower...I have the squeaky blower problem but chose to ignore it because I thought the blower was buried pretty deeply in the bowels of the dashboard?

Dave,
I've had several attempts of making the blower on my 300TE turn without problems, but there seems to be a problem with the motor bearings. Please tell how you disassemble the motor and the dust caps of its bearings in order to grease it - according to the number of different postings on this matter, we are several who wish to DIOurselves... Regards, /Jan Wickenberg

The picture you posted had the caps removed and lubricating the bearings is easy. But the caps may be crimped on and you have to do whatever it takes to get them off. I dont recall what I did exactly but you have to figure it out based on how the motor was assembled from the factory. If you cant figure it out you may have to just replace the motor.
Sorry I cant be more specific.

hmm, this looks like mine! went through hell trying to replace the , oh, crap forgot the word-bushings?? clearly visible on the picture (support the shaft). they are made of soft metal and are supposed to wear out. Talked to the Bosch tech. You should replace the whole thing because the wiring thins out and you cannot buy the right part. $99 from Germanstar.net. Pain in da.. to get to on a 190 (took me 4 hours the first time, can be done in 2, access to 201 chassis is from the engine compartment).
