another gem 4x4 problem question
Thanx for you guys being here!..So I had had the 4x4 engagement problem about a year ago ( would sometimes work and then not)... I removed the gem and washed it with electronic cleaner and blew it of..sprayed contact cleaner on all the contacts..reassembled and all was well for a year or so..now again..I noticed that if i disconnect the battery for a minute or so and reconnect it would work..would engage in 4 high and low..but would then not disengage unless i disconnected the batt. again..sounds like the gem is being reset with each disc. of the battery..so I assume the gem has finally gone bad..what do you guys think?.. Thanx! 1997 f150 4.6 lariat 4x4 e.s.o.f..stepside.. loaded..had this truck since 1998 and i love it!

Bad GEM and possibility of corrosion inside the fuse box due to leaking front windshield. I'm having the same issue. Its also quicker to just pull the turn signal/4wd/GEM 10a fuse.

Thanx,,pulling the fuse is a much better idea! anyway..no leaking from the windshield on this truck...no corrosion..the gem part # is F65B-14B205-Cb..from what I read I can use a cc or cd .. am I right? and is ebay the best place to find these? Thanx a bunch!

Sorry to inform you but the only way a GEM goes bad is when the front windshield starts leaking on the driver side. Its when it gets wet it takes out electrical components. The windshield leaks and runs right down the main harness's that plug into the gem.
Even if you find the same exact gem part number you will still need to get it programmed. Here is the updated part number from ford for trucks equipped with ESoF. F85Z14B205NA

You must have gotten lucky and the replacement you recieved had the same exact programming code. I didnt and had to have it reprogrammed, because 4wd didnt work, and the windows didnt work.
