Wife was running window down, when she tried to raise it we heard a thunk and it quit moving. I could hear the motor turning but the window was stuck down. Replaced the regulator/motor (it came in a set). Now the motor won't move down so that I can finish installing the bolts that hold the glass to the regulator. I can hear it clicking when I try the up position, but nothing in the down position. Yesterday I was moving the old motor back and forth just fine. Now the old one only rotates one way also. Could this be the passenger switch goofing things up? When I remove the passenger switch, driver side does nothing. With passenger switch installed, motors only turn one direction, and only when the driver switch is operated.
