Window Problems

I have a 2000 4 door grand am, and the front right window is having problems. Sometimes it goes up and down like it should and other times it wont do anything. What could it be?

Could be the switch is dirty, could be a short in the wires.

Have you tried wiggling the switch when it doesnt work ?
Does it make any scraping noises when its moving up.down ?

You might try some duster canned air stuff, if that doesnt work probly the window regulator going out.

i have had trouble like that with my buick. trouble was in harness that connects door to body. broken wire in harness where it bends
