i have no warning lights, and if i turn on my interior lights at all the buzzer comes on and stays on


edit: battery voltage gauge dosent work either, its pegged to 0 volts

 

No other clues? How were things working before now? Was everything fine? Did the changes all happen at once? Did you do anything to the truck or the electrical system immediately before this occurred?

Have you checked the battery? Any bad grounds?

This is the best I can do for ideas. Hopefully there will be others who can help more.

 

everything was working fine. just driving home from work then the door buzzer started going off and lost all warning lights and gauges except temp, oil and fuel. if i turned off interior lights the buzzer turned off
