Welcome to the club - my symptoms exactly!
Using the procedure in the FSM, I determined the switch itself was OK, the problem is in the motor.
Ordered a motor from CC on the 2nd, guy said it would ship the 6th. Called on the 13th, it's not in stock, said they'd call me back with an estimate of when it would be available.
After a couple hours waiting for a call-back, I called Vette2Vette, ordered a regulator & motor, it will ship Monday. Called the other place and cancelled the order!
Here's a link to a good write-up on changing the thing out:

Good luck and let us know how it goes.

That is what i found on my 85 vette with the later model window regulators, if the plug is not on straight and was pulled on an angle by the wires under tension. Or the repeated slamming of the door.
Not a problem since so check if the window motor works, when you close the door while holding the switch in the up or down position.

Window repair
I've repaired my switches and my motors myself. The switch's contacts get dirty, and sometimes all you have to do is get that switch apart (which isn't super easy, but doable) and clean them up nice.
The brushes in my motors were dirty, and all you have to do there is take the rivets out, pull the motors, take them apart and clean the brushes up. Pop them back in and you're good to go. A servo motor going bad is pretty unlikely. Much more likely that something is dirty in there. Anyone buying a $300 motor without wrenching on it a bit is, in my opinion, crazy.
