The passenger window on my 90 Mark VII is now stuck all the way down. I've owned the car now 6 mos. and it has worked reliably up to this point, although it was a bit louder than the driver's side. I saw a thread from MD-82 in May with the same problem- when the button is pushed, the lights dim a bit and there's a slight noise where you can hear the motor pushing but the window stays put. The thread I refer to entailed taking the motor out after taking the door almost completely apart, which is way out of my league. I have the panel off and have tried WD-40, yelling at it and hitting it. I guess at this point I may as well admit that this worked briefly earlier today- randomly, the switch just worked once, and I had it going up and down (though not all the way down) as good as ever. Then to prove to myself that the problem had been fixed I tried putting it all the way down. :slam So I'm an idiot. Does anyone have any suggestions?
