OK....here's the situation:

I upgraded all the electronics in my 2002 X5(new radio, new dvd, bluetooth, and sirius). Everything is working great. I drove the car into the office this morning and I have no fan/AC. Have any of you had this happen? Did something get unplugged? Do I need to disconnect the battery and reset the car system(had to do that in my M3). Let me know if any of you have come across this....I'd hate to take it into the dealer(I've had the car less than one month).
