The blower final stage fan resistor is known to fail. Symptoms are the heater fan speed varies regardless of the setting, the fan will not turn off when the car is switched off, or the fan will not switch on at all.

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
Blower stays on after vehicle is turned off. I have to remove the fuse each time to shut it down.
THE FAN DOES NOT COME ON WHEN PUTTING ON A/C. i DO HERE THE COMPRESSION SWITCH ON.
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.
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.
heater still blowing after engine switch off
Similar to as the description, all was fine then one day and after detailing the interior etc I cam across the fan running, afer i shut off the engine
Brought it to the dealer; fan relay switch ( $50 for the part, $65 for the labour)
all is well again
Thanks for a great website
after I leave my car overnight and morning the battery low
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.
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 :-(
Front of the car won't push out no heat or ac but the back do
Blower fan will not shut off when the engine is turned off. The ac/heat is not working properly. I have to pull the fuse in order to drive the car and not drain down the battery. The fuse is label for the ac but it seems to stop the blower.
Fan not working when air conditioner on at initial start. Blows hot air until enough speed gained to blow sufficient air to get air conditioning to blow cold air
It's mostly a trickle fan that out of nowhere decides to blow on high speed. I've been told it's a resistor.
I am on my 2nd resistor in just over a year,and just again in November 2011!!!! I replaced my 1st one in July 2010 and last month October 2011. Are their parts becoming low quality????????
I have replaced it twice.
heat works but blower is no coming on
My cold air is blowing, but when I put it on heat is blowing regular but no hot air.....any IDEA what it might be.
