side note to that, how hard is it to change the motor in a 93 (different dash)? Mine will make a click/ticking noise on low... I'm assuming something fell in there or it's just worn out....
Step 1 - Empty the glove box.
Step 2 - Drop the glove box (tabs on either side can flex in, allowing the box door to drop all the way down.
Step 3 - Remove power connector.
Step 4 - Remove cooling air vent (plugs into side of motor; you can't miss it.)
Step 5 - Remove four 10mm head bolts (may be 8mm; I've slept a couple of dozen times since I did this.)
Step 6 - Wiggle the motor and wheel out (it's no more difficult than a FL-1A oil filter up front and won't dump old hot oil on you! But it IS a bit of a wiggle) through the glove box, then drop it down.
Reverse to re-install.
My 1991 has a muffler that bolts to the housing using one of the mounting bolts for the fan; I'm not sure all years have that.
You may need to remove the BSCM to make clearance; I was doing that also, so installed it after the fan.
If you buy a VDO replacement, it doesn't have the connector but has two wires you're supposed to splice in; I used two .250" quick connect males, and fed each one into the blower connector from the body chassis. This allowed me to avoid hacking the car's wiring harness. (The Bosch plugs right in, but was $10 more and besides, my old Bosch only lasted 5 years. It WAS stifled with some plastic around the motor, however; a bag that probably got sucked in off the floor on MAX AC sometime in the past.)
BTW - this is actually laid out in the factory service manual; you really ought to buy one (and the EVTM) off of Ebay sometime.
