Is it possible for the FSR to partially work/fail? On my e46 when the FSR failed it's just dead silent, no blower activity/noise at all. In my x5 when this happens the vents are just not blowing air (as if the vents are closed) yet the blower still runs fine and changes when I adjust the speed. The only vent that works is in the rear.
Anything is possible. You could have a bad blower motor in which there is a dead spot on the armature. Just driving around could rotate the motor off the dead spot and the blower is working again until it stops at the dead stop again.
