Last night my window tilted forward and fell off the track. Somehow it manages to slip from between the rubber seals and right up against the door panel. I took of the stripping near the tweeker speaker AND tightened all the bolts BUT it is still trying to slip out of track about half way down. Any ideas of what I can do? Will old weather stripping cause this issue?!

 

You might wanna try taking off the door panel(the inside door panel) and then try raising the window up & down to see what/where the problem is, You're gonna have to reconnect the power window connector after you take off the panel tho.

If it's a manual window(roll-up) then IDK..

 

Yea I've done that and it appears that the issue is the stripping is weak?? I don't know how to explain it, but it's like the stripping gives under the force of the window and falls off track towards the front where the vertical weather stripping is. It's back on track now, but it's struggling and I have to be careful. Could this be a weak regulator?
