My passenger window works here and there. Sometimes it won't work for days. I took the panel off, disconnected the window motor plug and applied power directly to the motor and everything works perfect. When I plug the motor and put the meter to it while powering with either driver or passenger switch it reads anywhere from 2-6v and doesn't work. When i unplug the window motor plug and test the volts on the plug through either side switch it reads about 12.3v. Can anyone shine some light?
