The interior light that should come on when the doors are open hasent worked since I got the car. ('96 impreza) I have checked the bulb / all the fuses and they are okay and even traced the wiring from the roof, down the central pillar and into the wiring loom. Does anybody know where this is physicaly plugged in, or has any tips to finding the problem.

Thanks for any help

Download the wiring pdf.
Then you should be able to trace the wiring your after.

Thanks for that looks like it might be the door switches causing the problem
