Took my 99 Corvette to the store with the gf. Before we left she rolled the window down. When we go to the store she rolled the window up and pushed the lock button. When we came out from the store the window and door lock button no longer work. Even when I try to roll the window down from the drivers side it doesn't go down. What could be the problem?
Window regulator (probably). Common issue.
You can try to open the door, hold the 'down' button while slamming the door hard a few times. Usually works...for a while, but eventually you'll probably need to replace the window regulator (I have to replace mine now, slamming the door doesn't work anymore).
