power window problems...help.

passenger side window on my 90 fox will not work from either switch, passenger side or drivers. this problem has happened before prior to recently installing a new window motor. after the new motor, it worked great for a few months. now it doesn't - the window will not move one bit. fortunately this time, its stuck in the up position. before the new motor, i could hold the switch down and thump the door panel above the speaker and it would sometimes start working.


any ideas guys?

interesting. i did not realize the power originated from the drivers side.

side note - when i said i 'thumped' the door panel, i did that to the passenger side panel.
