HELP! I am the origninal owner of a 1992 325i with 150k in excellent shape. After some some minor body work this winter when I went to fetch the car the interior dome light and rears would not shut off no matter what the position of the switch. The shop spent several hours attempting to fix the problem, including replacing the door switches. All to no avail. They eventually claim to have found some corrosion on the bulb dome light bulb and the removal of that seemed to fix the problem. The logic of this escaped me at the time, but I was just happy to have the car back and working. The issue has recently returned and I checked the bulb and it is clean. The bulb socket is live even with the "switch plate" pulled off the "backing plate", in fact ALL three of the bulb circuits are live, leading me to think the bulb is not the issue, that the original shop "fix" was a coincidence and that there must be a short somewhere. Any ideas on how I might begin to track this down or where the short is most likely to be? I'd hate to be paying shop rates and my own fuse in the recent heat is pretty short. Thanks for any help.
