this problem started when I wanted to turn on my dome light.
Dodge Mechanic: Chris (aka-Moose), Technician replied 1 year ago

Use this diagram.

https://dl.dropboxusercontent.com/u/90220402/s104.pdf

Page 2 find the headlight switch. Follow the black/yellow wire down to splice 104. We want to find this splice on the truck and separate it. Turn the headlights on and find which wire is powered. Touch this wire to each other BK/YE wire noting which lights do work, so you can figure out which lights do not resulting in the fuse failing. This way we can start to narrow down the circuit to blame. Follow the left headlight wiring back to the main harness, open that harness there and that is where this splice should be. Let me know these results.

This is my 1st answer, but does not have to be my only answer. You the website and myself expect you to have a ~~~5 STAR EXCELLENT~~~ experience with my help. Please let me know if you are pleased by selecting a star rating above or by replying and saying your pleased. Not rating or rating 1-2 stars does not benefit you nor me in any way. Follow up and reply as often and when needed, there is no extra charge to do so.

Thanks Moose.

It goes to the instrument cluster. Unplug the cluster and retest the wire for a short to ground.
Ask Your Own Dodge Question
Customer reply replied 1 year ago
Ok but all the lights work on the instrumpet cluster.
Dodge Mechanic: sprinkles08, Chrysler/Dodge/Jeep master tech replied 1 year ago

The next step in diagnosing the problem is to unplug the cluster and see if the short to ground goes away.

Ask Your Own Dodge Question
Customer reply replied 1 year ago
Ok
Dodge Mechanic: sprinkles08, Chrysler/Dodge/Jeep master tech replied 1 year ago

If the short is still present then the issue is in the wiring, if the short is gone then the cluster will need to be replaced.
