I own a 2007 3500 I've been having problem with my rear driver side window since last thanksgiving. I lowered the window but i could not raise it up! I shut the door a couple of times then it worked. About two months later same thing happened this time shutting the door didn't work I bought a new power window motor same thing. I looked at all the wires they looked fine did more research seems the switch could be the problem I used the switch from a window that works nothing! So I bought yet another item THE MASTER SWITCH same thing oh by the way now both rear power locks don't work. please help
