Auto Climate Control

[BestX5]

I have a 2001 X5 3.0 with the auto climate control. Recently the unit seems to have issues that are hard to describe. The display shows the normal fan level bars as it has always done. But the fan itself cuts off and then 1 minute later comes back on. I have adjusted the fan to full speed manually and the same type of operation persists. The rear control continues to operate while the front cuts on and off. Has anyone else had this problem?

Have not had that problem in my 01 x5, but did have plenty of problems with the "bunt" (not sure if the spelling is right) cable, that is the cable that opens the heat or cool air from the center dial with the red and blue indicator. It seems your is just the fan.

Quite possibely a defective final stage resistor. Common problem. Here is the DIY

Definitely sounds like a final stage resistor. My 01 was doing a similar thing, not going all the way off, just slowing down a lot. The stealer replaced the final stage resistor and all is now better.

Good luck,
Dennis

Thanks for the messages. I will take it to the dealer since it is still under CPO warranty. Another $50. I think BMW has paid 10 times more in warranty repairs than I paid for the warranty.
