hi dear every body. my 525i bmw 1992 model ac fan does not work with the first three levels, only the forth. i was informed to change the fan resistance. how much is it and how does it look like. also, how to replace it. thanks a lot
ac fan works only on the forth degree..why on 1992 BMW 325i
This sounds like a blower resistor to me as well. The 4th, highest setting bypasses the control resistor and that is why it works. I found a web page that explains how to replace it if you're up to it. hope this helps

usually located under dash behind the cabin temp cluster after or part of fan controll switch.
