Hey everyone, I have a 2001 Pontiac Grand Am and the driver window fell off the track of the power windows. Is this common for these cars? Also how would I go about fixing it?

This is a common problem. there are two plastic attachments that are glued on the glass with an epoxy. they will either break or just come off.
If they break you will have to replace the glass,
If they just come off you can probably talk your local glass shop into repairing it for a couple of bucks.
