heres my problem. right hand window motor goes down but never up. neither side switch will make it go up. took panel off, checked wire that plugs into motor with continuity tester and it is always on. the light always lights. when i press the down button, the light remains lit. when i press up, it goes off. i have gone through 3 motors thinking that was the culprit. i dont think its the switches, how can both switches not function in one direction? what do you think it could be?
