Well Recently i wired up my power locks and then soon after i noticed that my rear defrost did not work. The button lights up but the defrost dosent turn on? I dont think its the ECU or whatever any ideas? I even tried disconecting the locks and still the thing dosent work so im out of ideas.
fuse?
Have you checked to see if you have power and ground back at the rear window defrost? 94
no, but where are the grounds at?
Fuse is fine i think
The ground is the terminal on the pass. side of car and the pos.(+) is the terminal on the drivers side of car, on either side of the defrost element on the rear window.
Us a multimeter to test for power and ground at the terminals to the defrost element, defrost must be on to test for power, the ground is a constant, [ground at all times]. 94
