I have an '04 Silverado that has a squeaky drivers side window when moving up and down. Does anyone have any suggestions to get rid of this annoying sound?? And yes, the window is clean!! Any thoughts would be appreciated.
Thanks!

You could try a little Armor All in the window seams/sliders. I've done that before and it's quieted the windows down; you don't need a lot just a little. It won't ruin your sliders either. I've been using Armor All on things for years with no problems.
The other thing you could try is some spray on silicone, usually found at any Auto-Parts store. :D

Spit in it!! Just kidding... Armor All works good, like chuck said..I've used it on a sqeuaking belt before..

i have the same problem with my 2000 driver door, so your not alone! but ill try the armor all thingy
