Replacing Final Stage Blower Resistor pack

[DeeM3]

Ok I wasn't able to find a DIY to do this so I figure I'll help others who would like to fix this but don't know how. First let's go over the symptoms so that we know we're repairing the right problem.

Symptoms:
All the lights on your digital climate control are working and the buttons respond but the blower doesn't blow any air.

Tools:
Phillips screw driver
Torx 20 driver
10mm socket, rachet and extension

Parts:
64.11.6.929.540 New
64.11-8 380 580 Old

First thing we need to do is buy a final stage unit. Costs about $100 at the dealer if you have the discount, otherwise it'll be about $125. Apparently there are two part numbers for this part they both look the same but I'm guessing the new one has been improved. Anyway you only need the new part the old one is the one you're replacing. Here's what it looks like:


Now we need to take off the driver's side knee bolster. This only requires you to remove two screws,one on the right side of the bolster and one on the left. Using the phillips screwdriver remove the following screws:


Now remove the speaker and footwell light.


Using the 10mm socket remove the 3 bolts holding the metal shield. And using the phillips screwdriver remove the obd2 port.

Now you should be able to see the footwell air duct. Remove it by pulling it.

With everything out of the way you should now be able to see the defective final stage unit. Remove it using the torx-20 screw driver.

Replace it with the new part and before you put everything back turn on your car and test the blower. If everything is ok proceed to put everything back, and enjoy the benefits of having a blower in your car again.

Looks like a flux capacitor to me.
