Had issues with my window motor a few months back, so I replaced it. Everything was fine for a few weeks, but then it stopped working again. Weird thing is, sometimes it does work, and what I've noticed is that if the drivers side works, the passenger may not (despite no issues with that side prior). I'm thinking this could be a relay issue, but anyone have any thoughts?

 

Pound the door sill by the speaker while the button is depressed.

 

I've tried that. Doing some more digging, I'm assuming it's the BCM causing the issue.

 

If you have a sunroof, check your drains to make sure the hoses didn’t slip off under the headliner. It’s a common problem and the water will soak the BCM and fuse box. You should be able to access the drains without removing too much, maybe just the A pillar trim and pulling the headliner down a little bit. There are some threads here on NAM on how people did it. I don’t think I’ve seen any posts about the back drains, but it would be a good idea to secure them too.

Securing the hoses with small hose clamps is better than with zip ties.

 

Thanks...I'll definitely check that out. Seems worth doing the hose clamps whether they are the issue or not.

 

Sounds as though you may have a faulty window switch. When operating the switch, try moving it left or right at the same time and see if that helps.
