In my 2010 Silverado, the driverside control for the front passenger window started to "act funny" about a year ago...just after my 3yr warranty ended -_- Any ways it started out that I would have to fiddle with the passenger control on the master control to get the passenger window to go down, but it would go up with no problem. Sometime over this past fall/winter when I wasn't opening the windows as much, the passenger window control on the master control stopped rolling the passenger window down entirely, but...it will still roll the window up perfectly fine. I currently have to lean over to the passenger door to open the window. Any help on fixing this without spending an arm and/or leg would be greatly appreciated.

 

Anybody have any insight?
