Supra Passanger Window Wont Go Up

KevinJZA70 · 09-26-2015, 04:34 AM

i have 1991 supra mk3, Passanger window will go down with the master and passenger switch, but won't go up with the master or passenger switch. it takes some time to play around with to get it to go up. Any suggestions what i should do? or what might be the problem?

My 'play around', do you mean shaking the window in the frame, or just using the switch to keep lowering and raising it until it goes up? I ask because my driver's side window will, on occasion, jam as I try to raise it. If I can grab the upper edge and shift it towards the rear of the car, It will un-jam and go up as usual. I suspect a worn bushing, but I haven't removed the door panel to check yet. It also tends to rattle a little bit as I drive, and I can make it stop by cracking the window and rolling it back up. Does anyone know of a source for replacement window lift track bushings?

It takes more power to go up than down. Take off the door card and lube the track and rollers. You can check the switch with a Ohm meter when its off. There are a few tricks to get the door card off. email if you need to know.
