My rear passenger window is not working properly from the driver's door controls. From the front seat, I can put it down, but when I try to put it up, it doesn't work. From the controls in the back, on the same door as the semifunctional window, it works both up and down. I was wondering if you guys know anything about this problem. I'm thinking it might be a dusty/grimy contact in my driver's side window switch, but I haven't taken off any of the door panels in my Lex yet and want to know if it's an easy endeavor and if getting into the switch with some wd-40 or something would be easy and help. Thanks.
