03 Impala Rear Defrost
im competely lost im very good with automotive wiring, but the rear defrost in this car is driving me nuts. Ive got 12v to the plug that goes to the window until I make the connection at the window as soon as I do this the voltage drops off. The ground on the other side is good and ive replaced the relay in the fuse box and the module behind the drivers fly window if anyone can help it would be great!!!
