Electrical ???

Check the ignition switch; jiggle the key around. Sounds like it's stuck in the "Start" position, so no accessory works.

We've learned these vehicles are known to leak water onto the fuse block & GEM wreaking havoc on electrical systems. If not dealt with corrosion will occur and require replacement. Windshield replacement or reseal is typical prevention fix, however according to one source: Safelite windhshield installer said "the problem wasn't the windshield in these trucks. Its the seam sealer running along the sides of the roof. He said they dry up and crack, allowing water to get behind the windshield and down the A pillar."

We try to figure out why the Windows keep going up and down wen the car is off.
