Hi, I have a 1990 Legacy Sedan with a factory sunroof which is not working. I'm trying to troubleshoot it and can't find anything anywhere that will tell me where the sunroof gets it's power. If anyone has dealt with this please could you tell me if the sunroof has it's own power wire or if it's tapped off another circuit and if so; which, and if the power wire runs up the A,B or C pillar. I checked the switch and it appears to be after the motor in the circuit(circuit tester indicates the black wire is ground and the other 3 wires don't respond to power input). I'd appreciate any help, what I've discovered so far seems pretty nutty to me and I'd rather not pull out half the interior just to test the power lead to the sunroof.
