    Replaced this failed part in January 2011 when the fan would not turn off. It seems to have just failed again in June 2014 but this time the fan won't turn on. It has stopped blowing briefly and then started working again 3 times in the last month but I think it's finished this time.

    I bought this car at 54,000 miles and the max button on the heater does not work and has not since I bought the car. Now the entire heating system seems to be acting strangely with the blower only working occassionally.

    Blower motor and resistor stopped working. No air (heat or cold) blew through the vents. Took it to dealership, discovered it was the heater valve that caused the issue. Dealer stated this is a known issue with X5 trucks since the 2003 model. Cost for repairs: $1987.00 for replacing heater valve, blower motor and resister.

    the blower is not working at all. I can feel heat when i put my hand over the heating vent but does not blow. The rear and front defroster work but i do not hear any air blowing

    Dealer charged $250 for parts and labor. I wished I had came across BMW forum and can take care of it myself and save money :-(
