Not sure that category this would fall under, so as they're electric windows, I chose Electrical & Lights. Anyway.... I honestly can't remember if it's always been like this (I don;t think so) but my front passenger windows does not go all the way down. It stops with about 1.5 to 2 inches still showing. Is this normal ? The driver side window goes all the way down. It doesn't sound like it's knocking anything on the way down.
