My '89 did the screeching thing too. Go to the hardware store and get a tube of graphite powder. Lower your window, squirt some graphite in the front and rear track. Raise the window a little, give it another squirt. Do that several times. If the tracks are dry, this should cure the problem after several cycles of the window.
If it still screeches, maybe someone else here can pinpoint the problem further.
