• Folks,
  
  The 90 Jetta's climate control blower motor has bit the dust, along with the resistor. It had factory air (everything is gone except the compressor which is free-wheeling for now). Are the physical mounting dimensions the same for any of the flavours of blowers out there? The replacement motor from any reseller for the ones with factory air is almost worth as much as the car. Tough to find at the pick'n'pull too....
  Here's the setup I have:
  
  and here's the blower without factory air, and 1/4 the cost....

• I don't see any mounting holes in the Non AC version.
  
  Then is there clearance from the rear of the motor so it wont hit the dash?
  
  Maybe you could swap the motor and keep your housing then use the resistor as well?

• They  are not the same. The ac one screws in, while the non ac one just turns in with it's own cam locks.

  Useful repair explaining how to fix at almost nil cost. The fan cools the resistance that reduces the current for the low speeds. The fans get dry bearings. The motor sucks more current, the resistance gets hotter, the fan is slower due to stiff bearing, resistance is now double whammy hotter. Pop goes the thermal fuse. Or if you were a cheapskate and stuck in a bit of wire, eventually the dashboard self immolates. Oil the bearings every couple of years to avoid this hassle.

  $35... but too bad the canadian dollar is down so much.. a month ago you would have had a sweet deal on that!  
  
  but definitely try smutts' suggestion first

• try big_b on vortex. He has lots of mk2 parts. The diesel and gas stuff is the same as far as I know. You could swap to non AC under the dash

• Well, I found some of these AC puppies when I went to visit family, and I discovered something when I went to mount it that I didn't see when I pulled the old one out...(it was dark out)...
  It appears the motor was operated on full blast a lot, because the bottom of the cut-out in the ducting was seriously "rubbed" allowing the replacement to wiggle a lot. it wore away so much plastic there's a gap at the bottom and the new one does bolt up...but the bolt holes are now "slots". It allowed the blade to actually rub on the bottom backside and wear away a good deal of the outer section of the "blade".
  Nothing a few blind nuts and some epoxy won't fix, but what a PITA.
