Bought truck used, rained and lost power windows, radio,gauges,4 wheel drive light stayed on, vehicle started on its own and many other problems in truck. Read on internet about GEM module. Replaced windshield. Everything slowly came back working, except for all instrument gauges on dash. Does the GEM module control instrument gauges?

 

Seal the windshield leak first then replace the GEM.
Good luck.

 

Thanks Bluegrass, already replaced and resealed windshield. That took care of water leaking. Now onto the GEM module. Wish me luck!
