That's my next trick. Need some time. Any suggestions /links on how to? I could figure it out, but easier to watch someone who has already invented the wheel. Chaffed (grounded) wire sounds very logical. This X5 does not have a phone loom. Blown fuse sounds like a short.
Other posts led one to the spare tire compartment and said there could be water in there? I've removed the spare and did not see any electronics other than the battery.
