I have 2002 1500 4x4 gas. It sat idle for about 6 months now there us a clicking sound coming from behind dash on drivers side. It keeps running the battery down. Where do i start looking for problem.
The dash lights were flickering and
there was a smell of wire burning.
Put in new battery and it ran it down.
Sounds like you have a short somewhere. You need to find which circuit and repair the wiring.....https://www.youtube.com/watch?v=KF1gijj03_0
Check the wiring under the hood for critter damage. Sounds like you had an unwelcome guest while it was parked. HTH. -Jim
