Re: Light problems on 2002 F-250 XLT Super Duty
I don't know if you fixed the problem, this thread is two months old. It does sound like the GEM Module. Did you check to see if there was water behind the fuse box? That is where the GEM is located. Also, if you have cab clearance lights, water could be leaking in through one of them. Good luck.
