I drive a 2005 325XI. Air Condition is not working. I don't know much about cars, so I'll tell you what my mechanic told me. He said the car is not turning the compressor on. However, he said the compressor works when externally powered (apparently it's a 12V power), and it works when he turns it on using his computer. It just doesn't get turned on by the car itself (which is he said is a 4V power). He checked the fuses / electrical and couldn't find the problem. He also said changing the compressor is very expensive and may not fix the problem. Anyone have any ideas??
