Hey guys I'm new to the forum, and have searched quite a bit on here for my answer to no avail. I have a 2004 cummins 3500 four door. The right rear window will not roll up or down. I know the motor is good because I jumped it right to the battery, and it goes up and down. I changed the switches between the passenger side door and the driver side door and no difference. Am I over looking anything? It's almost like the switch isn't changing the polarity like it is supposed to. But when I change the switch with the other side it still does the same thing. Any suggestion would be much appreciated. Thanks in advance.
