I gave the entire mechanism with the window attached a damn good jiggle and the window support became visible. I unbolted the window, removed the inner window padding and removed the glass. I could then move the mechanism and motor enough to get at all three bolts (yes, more than just the two I thought). > Once I have the motor off (or rather, if I get the motor off) and get it > working again or buy a replacement, can the motor be re-fitted anywhere on > the toothed mechanism? What I'm really asking is what is the procedure for > re-fitting the motor to the toothed mechanism? With the motor out, I rigged up some wires to test the motor. Given a live current to either terminal while the other is grounded actuated the motor in either direction - good, so the motor isn't broken ... Back to testing the wires - 10V +/- depending on the direction the switch is depressed when the wires are plugged together. I'm talking about the Red/White and Black/White wires that are inside the door and go to the motor. These connect to Red/Yellow and Black/Yellow through a connector block just inside the engine bay. Hmmm - okay, next I find which wire corresponds to which direction and ground the other wire to the chassis. Voltage passed (again around 10V +/-), but when I ran a resistance test against the chassis, it came back bad. Essentially, the motor is not grounded when current is applied to it. I put the window back together and located the down wire, spiked that and ran to ground. I could then get the window up to the top. Great, I suppose :) I tried running a new ground from the relay, but ran through too many fuses so I kind of gave up on that line of attack. Upon re-inspection of the wiring diagrams, I glean from the "later" model diagram that this area grounds to point E4 - between the handbrake and the ignition switch. Is this right? Given that the passenger side window works fine, I'm presuming that the problem is on a ground wire from the driver's side switch. I've given up for tonight, but am I on the right lines here? How do I get at that ground point? I don't really want to bodge it by just snipping the wires and running new grounds. Again, input from "been there, done that people" would be very much appreciated. TIA. Paul 1989 900 Turbo S
