:iagree:

I had the same problem in the end of last year, but my service center in HK said that it was something leaking behind the LCD display monitor. They changed the leaking thing and then I had A/C back again. However, it costed me about HK$14,000 (US$1,800). So fxxking expensive! God dam it!

Had the same problem as you guys. Had to replace my blower resistor and aux fan... MUst be typical problem of an X5. I drive an 02 X5 3.0d euro

I have a similar problem on my 2001 3.0 X5 and working on it right now. But, instead getting the $400 OEM aux fan, I've installed a replacement fan (16", 2100 cfm, $70 @ eBay). Easily installed and looks original. Here's my problem, when I plug the wires together, the fan went on and doesn't go off unless you unplug the wires. I suspect a damaged relay but do not know where to look for the aux fan relay or the a/c relay. I've tried the Online WDS with no luck. Anyone here can help me with any info is much appreciated.
