The MB part number on it is 124 820 27 10, but that may have changed - I remember that the new one was somewhat different - mainly smaller (same mountinng though). Chris

My 1992 300d has a dead blower....I think

no Blower
no compressor engage
nothing but hot air when driving


Do I access the blower and regulator after removing the wiper assembly

Short answer is yes you remove the mono wiper first.

Do a search on removing the blower in a W124 its covered well on the list.

the regulator is under a plastic cover, you need to remove the cover and then twist the regulator/heat sink assembly to the side to remove it.

If you're not getting a compressor engage then maybe there's a larger problem. Above the fuse box and towards the center of the car is a three wire plug. It's tough to see. One of the wires is hot, the other is ground and the third is the signal that sets the blower speed. If you ground the signal on the plug side (the side attached to the wire) and pass 12+ to red and 12- to black the fan should blow full speed. I would do this first just to help isolate the problem. The fan will pull upwards of 20 amps.
