I'm having an issue with the passenger front window. It occasionally makes a loud popping noise (so loud that it actually scares whoever is sitting in the seat). It is highly annoying, but hasn't actually been a problem until recently.

Twice in the last week it has gone down, and won't go back up. The first time I took the door panel apart, and I was trying to figure out what the problem was when something snapped back into place, and everything seemed like it was normal. I took the plastic pieces off the lift mechanism (the ones that actually go into the window) and they were fine.

I've tried searching around, and I've seen the RX for the window, but I'm not sure that would fix my problem. Thanks for your help.
