Electrical problem
1998 Ford F150 V8 Four Wheel Drive Automatic 95000 miles

My 1998 F-150 SC 4x4 was left over the winter in my yard covered with a tarp and the battery connected. When I returned off holidays after 3 months the Windshield wipers and spray, the power windows and the 4x4 selector switch does not work. I had the vehicle into a repair shop for 3 Weeks and first they said it was a faulty gem module which was bought and installed and nothing worked. Then they said it was the fuse panel board attached to the GEM that was not grounding correctly so we go a used one in. They said all the electrical worked that night but the next morning all the above items (windows, washers, 4x4 switch) all failed to work again. They said it could be a grounding problem but Where? Please give me some clues where to look. This is a great truck other than these new problems. Thanks

There is a "battery saver" relay in the fuse block under the dash, It may be sticking, making the GEM lose power. Do fuses 22, 25 have power all the time? The 4x4 switch is tied in with the wipers, via the GEM as well. Is the GEM giving power out to the things that dont work? Does the GEM have power into it?
