I would start with replacing the fan too. At least you would have a working fan in the case of stopping in traffic on hot days. Also that would rule out the fan as the culprit.

With INPA diagnostic software you can test the aux fan and read individual climate control (IHKA) errors. After verifying proper refrigerant charge, that's where I'd start.

I bet you can trade a local with INPA a 12-pack and he'll hook up to read your codes. Try the e39, e38, or e46 boards if you can't find a friend with it here.

The controller will not allow the AC to start of the aux fan is broken. Correct. One of the "startup tests" is to check whether the pusher fan is ok.

What do your mechanic need to be replaced? Does he meant control panel? If so, the control panel cost less than $200.00.
