Ok, so after never using my rear windows, this morning the rear are a little foggy so I decide to roll the windows down to cleam them up a bit. Now I go on to put them back up, and only one goes up while theo ther one makes a popping noise. Broken REGULATOR!

So anyways, I just want to put the window back up, but I have a rear airbags in the door, so I was wondering if anyone else has changed their rear regulators with rear airbags? Anything I should be cautious about? Do I need to do anything special?

Took the cover up, and I just pushed the window up underneath the other foam cover, so now im wondering if it's actually the regulator or the motor.

Common problem with these windows. Luckily there's an easy solution:

It could just be the cable slipped out of the wheel track. That's what happened to mine. I found the cables to be dry and crusty, so I loosened the window motor, reset the cable and lubed them up with some lithium grease. Then I just cycled it up and down a few times to make sure everything was good and I haven't had a problem since.:)

I still cringe a little whenever I put that back window down though.
