1989 Grand Marquis drivers window goes down but not up and its not the motor what could the problem be?
It's all part of a kit. You'll have to replace the whole kit to gain success.
1994 Grand Marquis drivers window motor works but window doesn't go down or up but the window does work itself downward while driving so what could the problem areas be?
Electric Window problem If you haven't checked already, check to see if the window is in the track and not out of the track and then check the regulator to see if one or more teeth are broken or may have come disconnected. Hope that might help also sometimes the motor works but doesn't have enough strength to lift the window had that problem on my 1987 Nissan wagon had to rebuild the window motor…
