climate control , a/c
another issue again, so i went to my garage to diagnose a/c issue, he told me there no leak, but the main reason why i dont get cold air is because my climate control only send 4volt to the compressor and it doesnt get enought electricity to work... anyone have a DIY solution?? beside replacing this 1000$ shit

+

he also told me, my aux fan is dead, is it a repair ASAP or no ?

Does your a/c work sometimes or never? Are you having any other electrical problems?

Disconnect the aux fan, start the car, and see if the compressor ever turns on. On e39's a shorted aux fan can cause IHKA problems. A used IHKA (if you still need one) looks to be around $250 on ebay. For e39's, if you buy the same one (same buttons) it doesn't have to be coded to the car ($$$). Not sure about that for e53's so do your own research.

"...replace climate control..." is a VERY broad description.

I would suggest that it is not possible to advise based on this info.

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.
