My wife has an 04 GTP and the rer window defroster is not working any advice would be great. I have checked nothing.

Check the easy stuff first.

Check the fuse. Make sure the switch lights up when it is turned on, indicating power is going to it.

There is also a relay that could be bad. See owners manual for fuses and relays.

Check the wires are the rear of the window, one could have fallen off, or broke off.

Sorry for the slow reply thank you for your help. No idea what was wrong with it working fine now.

seems strange but i have also had issues with two electrical things not working, then just randomly fix. one of the LED's on the air unit didn't light until i hit it, no problems since then, and when i bought the car one of the speakers spazzed out occasionally and made tons of racket, then it just quit doing it. I think these cars are prone to strange electrical things
