How do you fix a power window on a 1990 Camry that rolls down but not up?

the track may not be align and its binding somewhere inside. you have to remove the trim and the plastic water seal so you have a better view. if you can roll your window manually the better but first you have to disconnect wiring harness from the power window motor. if not just try to roll it up and down using its own switch and check where it binds do the necessary adjustment. check also your window gasket maybe its the culprit. goodluck.
