window noise....

i remember just reading about someone having a problem with their power windows not working. Mine still work normally, but they make like a cracking noise everytime i move it. like when its closed all the way, then i open it just a little. when i leave it open, and go on a little bump, it makes a noise like the window is cracking, but its not. (hopefully) i found out it only happens in the spring/summer, or when its not raining no more... only on the driver side window.


has anyone had the same problem or know whats wrong? anything i could try to fix this? thanks. by the way it a 1995 4door.
