Yesterday I took my truck in to have the plugs and fuel filter replaced.

When they gave me back the truck as I was pulling out of the parking lot the A4X4, 4X4, 4X4LOW and Low Washer lights started flashing. They flash 3 times, then it looses power for about two seconds. It does this about every two minutes of diving. Then after a couple miles the overdrive off light started flashing continuously.

I took the truck back to the shop, the guy plugged the computer in and said my 4X4 switch was faulting (the switch in the cab to turn on the 4X4). He cleared the code, and sent me on my way. I drove the truck for about 20 minutes and everything seemed to be okay. Then I stopped at home for about an hour. The next time I get in and drive away it's doing the same thing. But now when the truck is turned off at the key, the front and rear fans keep running.

What the hell did this place do to my truck? Anyone ever see this before?

Just thought I would post an update on this. They ended up pulling the main fuse box/GEM - the GEM appeared to be okay, no noticeable moisture, but the fuse block was corroded. They are trying to find a used one from a salvage yard. Hoping to get it back soon.
