This 1997 Ford F150 needs the GEM module changed due to multiple conditions. To see testing that lead to this repair please click here. The GEM module is located t the rear of the interior fuse box.
The first step is to remove the trim panel that covers the gap between the upper side of the steering column and the dash. It just unsnaps from the dash. It makes it a little easier to remove if you move the shifter all the way down to drive 1.
With that out of the way the lower dash cover can now be removed. Most of the screws have 7 mm heads but there are two that have 8 mm heads.
Those two are at the lower edge of the fuse box.
One wiring harness needs to be disconnected from the panel.
Now the screws for the fuse box can be removed.
The wiring harnesses can be removed from the back of the fuse box. Two 10 mm headed bolts at the center of each connector.
Next remove the tube brace from around the bottom of the steering column. Four fasteners with 13 mm heads.
Now wiggle, pry and twist the fuse box and GEM module assembly down.
After the assembly is down far enough unplug the remaining harness connectors from the GEM module.
The assembly is now free of the vehicle.
The GEM module is held to the back of the fuse box by three phillips headed screws.
Easy to remove Now.
With the three screws removed the GEM unplugs from the back of the fuse box.
I put it all back together and checked my repair for power to the driver's power window switch.

try a salvage yard that has an expedition or an f150 pickup and take the parts off and install in yours disconnect the negative side of the battery and you shouldn't have to have it reprogrammed
