Replacement GEM needing Set up????????/
My gem in my 98 f150 started giving me problems with my driver window, i went to the junk yard and pulled a GEM out of a 99 expedition. my truck and the Expo are both 2wd. I plugged it in my truck and my truck seems to run and idle fine, my window works but now my air back light stays on and my windshield wipers dont work, untill i hit the HIGH speed then they go crazy and i cant turn them off, also even with the keys out of the truck my windows still have power.
is this a computability issue ? or does the GEM need to be flashed or programmed with my truck>?
