Anybody know the route that the wiring for the interior light takes?? Mine isn't working at all. (using the switch or when opening the doors). I've checked and changed the fuse (no. 15 in the fuse box at end of dash), and I've checked the bulbs. All are fine. I have also checked that there is power at the fuse, and there is. Checked the bulb terminals for power, there is no power getting there. So the problem is somewhere between the fusebox and the actual interior light unit. Everything else in the unit works i.e. sunroof switch, airbag light. It's just the two lights bulbs that don't. Had a look at a wiring diagram in ETKA, and to be honest I don't have a clue what I'm looking at. Anyone able to help???
