Yesterday I called the dealer and asked how much the factory Final Stage Unit was for my 2003 X5, and they said $144.
At that price, I figured, what have I got to loose in attempting repair of my FSU like you described?
A little digging of the potting material, some soldering and an hour and a half later my AC - heater fan is working great again

! Thanks, Heising, for the fix and the pics, they really helped make it easy! $0.00 is real nice!
I posted this just to let googlers know that this fix is current and for real. Pay the .25 cents to get on board at Xoutpost here and get in on the action!
Fish ON!!
