I have a 1998 528 and the a/c blows warm air, it would vary fan speeds on its own and now is only blowing warm air. I had it checked for freon and it has gas in it so I am wondering if anyone has a clue as to what needs fixing
the aux fan is working fine and I have not heard of the FSU so I looked it up...where would I find this on the vehicle...thanks for the quick response also
