The rear dome light does not come on when opening either of the rear doors or the hatch. The rear dome light will work from the dash switch. I pulled both rear door switches and I am getting no power to the switch from the wires on either side. I tried with the lights on, with the car running and still nothing. Front dome light and front door switches work fine. Any ideas or am I missing something obvious here?
