This is my first post, and i would just like to say hi to everyone. I was thinking of posting in the new members area, but i need to address this problem quickly. I have a 1999 Chevy Silverado LS standard cab. Today i was rolling down my front pass side electric window, and i held the button a little longer than i should of. The window was all the way down, then i heard sort of a crunching harsh noise. I didn't know what it was, and was able to roll the window back up, but it was going slowly. After that, the window is now stuck in the up position. The window was always a little slow to roll up and down at first, but now its just not moving at all. I can hear the motor running in there though. Has anyone had similar problems? How can i fix this? Best case is if i don't fix it myself, i can go to my mechanic with some information on what it might be. Any help is appreciated.
