Bill -- it occurred to me that you never got an answer to this question. There is a blower control amp behind the glove box. Go to your favorite Worldpac vendor's site and click "blower regulator" in the climate control section. That's what you're dealing with.

Thanks Russ,

I will have a crack at it.

Thanks Russ, Yipes! Remanufactured it's $162!! I hope it is OK or that it can be rebuilt with Radio Shack parts....

I have the type 2 ACC system with a new aluminum body servo. The system seems to work OK except when in Auto HI the fan never goes into full highspeed like it does in Defrost mode. Is this normal?

Not sure, Bill. I don't have any experience with the servos and frankly, plan to stay away from any cars so equipped. I see that Performance products has a solid-state control system to replace the servo completely...only $600!

I will say that the fans on my W123s will blow at high speed in all modes.

Since you seem to be drawing a blank in this thread, maybe you want to start a new one under a different title. Did you see the thread on this Bentley forum?

Hmm....I wasn't aware Bentley even published manuals for Mercedes, let alone the W123.
