WTF? I know the GEM controls the interior lights...and a host of other crapola it really shouldn't...like my random ABS light that turns off my auto4x4. :\
I have a Ford F-150 and I had a leaky windshield a while back, and the dealer said I needed to have the GEM module replaced. I've already taken the old GEM out to look at it and put it back in, so I know how to replace it. But if I buy a new GEM module, does it need to be programmed by the Ford dealer before it can be used? I would hate to take the truck to Ford for them to replace the GEM because they charge an arm and a leg for it, while it's so easy if I just replaced it myself.
Prior to removal of the module, it is necessary to upload module configuration information to scan tool. This information needs to be downloaded into the new module once installed.
I had to have the GEM and fuse panel replaced on my '98 not long after I bought it. The truck had some weird electric problems and the repair took care of they. The dealer did it a no charge, then sent parts to Ford. Never found out what was wrong.

As I've posted about the same leaking issue madsonp really knows his s*** so thanks so much however I do wonder if this is obviously such a big not to mention pain in the a^^ problem how can we contact ford and possibly have this looked at as a possible RECALL issue has anyone thought of this if so what was the outcome or are you still thinking? if enough of nus complain maybe we'll see results.
The GEM is bolted to the back of the fuse box.
Sometimes though the fuse box gets water in it and causes the same problems too.
Don't know if it was water, but my 2000 Nav just had the fuse panel replaced today. The blower motor was stuck on when the key was off, draining my battery.

HELLO,
I want to see pictures about de GEM, for the history problems mentioned by other fiends Im thinking that i need to get one.. please somebody show me the electrial part. thanks
I drive an 02 Expedition 4x4, and recently my running board lights and interior lights are not coming on when I click the "unlock" button.
Think that's the GEM module?
Dealer told me today the module is $512!!!
The GEM controls a whole host of stuff in our trucks; From running board lights to transfer case operation. There are about 40 or more functions that the GEM provides power for.
If the GEM got wet after it was dry and the windshield was resealed the reseal was not done properly. I think the only other possibility would be a sun roof drain leaking inside.
