You need a wiring diagram so you can track the circuit from the fuse block to the light to find the short. You might want to check the socket first to make sure that nothing is wrong there.

thanks for the info john. where would i get my hands on a wiring diagram.................dawg

 

Pull the dome light fixture out & note the wire colours.
You could pull the bulb(s) out for a while to see if the fuse still blows before you tear the truck apart tracing the wiring.
Touch the dome light switch once in a while to see if it is warm or hot.
Maybe Franklin2 has a link to a diagram?

Do you have any aftermarket running boards that light up when you open the door?

 

no after market any thing wiring. ...............dawg
