change your light bulbs

What usually gets overlooked is the ground side. Check the continuity to the chassis ground from the bulb socket over the black wire.

been checking that,continuity in the left and right harnesses is good, have power to the junction block into and out to the left and right but nothing when I plug those harneses in at the stop lights,bulbs are good very weird thanks

EinST

Hmm, you keep saying good power into and out of the junction block. Are you reading good voltage at the bulb socket with the brake pedal depressed and none without? Is that with or without the parking lamps on? To be clear, the stop lamp bulbs usually have two filaments, one for the stop lamp and the other, parking lamp.

no I have power out of the junction block but none at the socket for the brake light all other lights work fineso I guess nothing between the socket and the junction block,thanks greg

EinST

So, you either have to repair the wiring or splice in a new socket, depending. The only thing I can add is to make sure to seal the splices good (with solder and heat shrink tubing if you can). Good luck.

Under the hood, in the fuze box there is separate fuzes for the trailer lights, and the trucks lights. I had a problem with my 06, and thats where I fouund the answer, good luck.
