Soundguy said:is that a gem wireing issue? I know when i had a water leak from a top cab light.. water ran down driver side pillar and got GEM module wet.. and i had that OD light blinking on my 99 350.
removed and resealed all my cab lights and it took care of the issue. AFTER i got a new GEM module![]()
