So the other day i got in my truck to go home from work and the truck struggled to even start but it did. Then i noticed that none of my gauges would work at all and my radio didn't work. I then tried everything in the cab and there was no power to anything in the cab like lights, locks, and windows. The odd thing was, was that my turn signals and cruise control would still work.
I have been having what i think are electrical problems and it started with the gas gauge not showing the correct level in the tank. Then it went to when i shut my truck off, a random light (ex. headlights or license plate light) would stay on and kill my battery. Now my entire cab has gone to complete failure and I'm just throwing out an S.O.S. to see if anyone has an easy fix or i should take it to a mechanic.

 

Yikes. I'm no electrician so I may not offer much. Sounds like it could be a big problem...
Did you check all fuses and relays just in case?

 

hope you have a multimeter.. start at the fuse box
