A/C Fan Blower Problem
 

Have had the intermittent fan problem for about a year... about a month ago, the fan would not stop blowing when the car was turned off. Only rememdy was to pull the big 50amp fuse. Ordered a FSR and replaced it. Fan worked fine at all speeds for several weeks until a few days ago... no fan at all again. The fan has made a "chirping" sound from time to time which leads me to believe it's the blower unit. Anyone have any experience replacing the blower unit? Any suggestions?

pretty simple, remove dash, replace blower, take about 3 hours to du.

Thanks.

Any advice on where online I can find a procedure for AC Fan Blower unit replacement? Thanks.

have you already fixed the problem?

I had a similar problem it was the Final Stage Resistor. Although, my didn't stay on after shutting off the car at times mine wouldn't start until i restarted the car. I also had air blowing slowly. Before you replace that blower unit make sure you know it is the culprit not the by product of the Final Stage Resistor.

A/C Fan Blower Problem
 

The problem was a "dying" fan blower unit, which met its final days at about 125000 miles. The Final Stage Resistor did fail just prior, and as I mentioned in my original thread, exhibited symptons of the fan staying on one speed (even after the engine was turned off in my case). Replacing the FSR confirmed this. The fan blower unit was an eight hour job, due to complete dash removal, etc. It probably wouldn't hurt to be diligent about changing your cabin air filter to possibly (and I say possibly) prolong fan blower life! After replacing fan blower unit, noticed a lack of cold air when stopped in traffic. Auxillary fan was the culprit there. As you would guess, A/C works beautifully now.

Nice work getting it back and working. 8hr job removing the dash sounds like a Pita. Hope mine doesn't croak.

My 03 X5 (3.0) has the same problem, fan keeps blowing after car is turned off, that drained my battery to dead, I need jump every few days. When I read related posts here, I believe the FSR/FSU is the problem and I am going to replace it like others did.
But when I try to order part online, I see this kind of note: “Final Stage Unit Only used on Cars with Automatic Air Condition” (like this one). I got confused, my X5 does not have automatic air condition (I need to manually turn the dial to set fan speed). Here comes my stupid question: does my car also have this kind of FSR/FSU? If not, what caused my fan blow problem after car off? If yes, what is the correct part (FSR) should I order?
Please help. Thanks in advance.
