in addition to my other problems, i believe I have a general module problem. none of my interior lights work besides the visor lights as those are on a completely different circuit and will only operate if 1. the exterior lights are on (city or fully) and 2. the slider for the mirror is open. my question is (since I don't wanna buy a new one) can i possibly repair my GM? such as resolder old/bad connections?
note: money isn't the issue so buying one isn't out of the question. and I have the black GM. is that found on early
cars or later models? mines a 1990 525i m20
