Here's a strange one. I guess by coincidence the old motor only functioned one way (tested it when I pulled it out). I replaced the motor and now the window goes up and down when power is applied directly. However if I do either passenger side or driver side switches, it will only go down. This is the passenger side window. In the morning I'll stick a test light to the harness where it connects to the new motor's pigtail and see if I get anything on the switch UP position. Off the top of anyone's head any idea what it could be? Would a bad window lift safety relay cause this? Driver side functions normally.
