My rear defroster will not activate when I press the switch. I pulled the switch, replaced it and connected the harness. I see a light on the other end of the switch on, but the indicator wont turn on when I press. Randomly, sometimes when I start the car the rear defrosters will be on, but then won’t turn off until my car is re started up. Is this problem associated with the ICU, or can it be faulty wiring. I feel like running new wires to rear defrosters would be a pain in the a$$. :shrug:
any ideas?
Yup ICU. Pop out the ICU and take a look.
