Check for the ground wire that screws to the parking brake bracket is not broken.

Post by: 123 pugsy on October 14, 2007, 05:24:11 am: Did you just buy this truck or have you been driving it and this is a problem that just occurred?
Have you pulled the instrument cluster out and checked the circuit board on the back of it?

Sounds like you have to lose the football sized bundle of wires first and try to get your wiring back to stock condition.

After that start rewiring all your add on stuff such as door poppers...lights...etc...

Post by: Captkaos on October 29, 2007, 10:17:07 am: That is just a bulb that gets power at the time the high beams get power. Is high/low beams working? Check the wire going to the cluster to see if it has power all the time.
