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 at 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.
Almost there.
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.
The GEM of course could be part of the problem but from your description I would start by determining what the cranking issue is first. Faulty battery voltage could also cause window issues.
I have a 97 ford f-150 4×4 my driver’s window went down & won’t come back up passenger window does nothing and when the truck is hard to get started like the battery is dead
Could it be the (gem)or (ctm)
Since all problems except for the starter issue happened after the ignition switch was replaced, I would concentrate on that repair. Double check part numbers and installation procedures. Many of those switches are adjustable.
i have a 2000 ford f150, when i start the truck, a few seconds later the starter would engage, replaced relay on firewall, still engaged, i pull ignition wire off relay it stops, so i figured it was ignition switch, replaced. so far no starter issues, but now i get. when key is off, radio is on, windows work, gauges cluster has low voltage to it, i turn lights on and heater blower turns on. i thought i had a short. i pulled radio fuse and it seemed to work for an hour then it started again. also now 4×4 is switching on and off. im thinking its the GEM or power feeding back to fuse block.??
The window seal is also bad i can definetly tell that it leaked right in on the driver side i had the truck sittin for 2-4 days straight it rain non stop for 2 days …
