Blower won't turn off.

I have BMW x5 3.0I 2002 81,400 miles no prior
maintence.
The blower continues to run with the engine off.
Pulling a 50 amp fuse labeled blower is the only way to stop the blower and prevent the battery from
running down.

Would be very thankful for any help.

Your problem is the final stage that controls the fan needs to be replaced. It is located just behind and below the glove box behind the upper carpet trim. Just remove the carpet trim and you can see it, the connector is a black 5-pin, you'll see its real easy.
The final stage may be available online somewhere
The dealer will have these as a stock item, they fail all the time.

The wiring diagrams for your blower system are attached below as well as the only pic I could find of the final stage units location

Dr Hagerty.I have a similar problem with my 2000 528i. Where is the final stage that controls the fan in this vehicle and how do I get to it?

Thanks in advance.

It is below and behind the glovebox.
First remove the plastic cover just above the passenger foot well area by pulling it out(it pops out, no tools required) then remove the screw that holds the carpet in place and the carpet pulls out to the rear.
The final stage is behind a piece of open cell foam(if the foam is still there) remove the torx screws and install the final stage. You kind of have to "stand on your head" to see the final stage. If you have already purchased a replacement you will be able to visualize its installation.
Its pretty straight forward, give yourself half an hour.
BMW warranty time says about 15 minutes.
Good luck and repost if needed!

While the heater was operating, The digital display began flickering then went blank. The heater now remains on even when the key is off and out. I replaced the final stage module, but the motor continues to run as soon as I reinstall the fuse (with the key out). The digital display still is blank. Any other ideas besides replacing the final stage?

Ianradcliffe, did you get this figured out? If not, do any of the other accessories work without the key?

Yes. Fixed. The final stage was fine all along. The problem was the climate control computer. Bought a used one on eBay for $150. Works like a charm.

We just bought a 2003 BMW X5 and when we got it home we realized the heater fan was not working. We called the previous owner and of course he said it worked before. The fan speed indicator does work but the fan does not. When we open the rear vents and turn the dial to red (heat) we can hear and feel the fan. This does not happen to the front vents when we turn the front dial to red. We have tried the auot settings and the manual settings. Is there anything we missed?

Go to Realoem. Com and look for part number 64-11-6-923-204. This is the potted semi-conductor device that controls the fan and it will require replacement. It is called a final stage.

The key(s) will require reinitialization. Go to the car, open the drivers door and get in. Shut the door. Put the key in the ignition and turn it on, then take it out and then hold the unlock button and while holding the unlock button push the lock button 3 times, then release both buttons. Then what should happen is that all the doors will lock and then unlock. If there is another key(s) then do the same process of holding the unlock button and pressing the lock button 3x. Do not open the doors or insert the 2nd key in the ignition for the procedure, just press the buttons on the subsequent keys (up to 4 keys) When you open the door or start the car, the initialization session is then over. The dealer charges for this operation, can we count on you for a reasonable donation today?

Could you tell me if the fan speed changes when you go to defrost or when you change any other setting? I'm asking because the speed control does not usually fail in this manner. The device that controls the fan speed is called the final stage and it is possible that it has been compromised and I do not wish to give poor advice. Thanks for using 2carpros!
