Hi,
I have a 2002 110 TD5 Station Wagon, the rear interior light wasn't working when I bought it, I took the bulb out of it and tried it in the front interior light, it worked. I then took the bulb from the front and tried to put it in the rear light, it sparked as I put it in and knocked off the radio and interior lights. Checked the fuses under the drivers seat and also the ones at the gearstick, all seem in order. Anyone got any ideas how to fix?
