All running lights are out

[JBain]

Hi everyone,

I'm having trouble figuring out why all my running lights are out.

Brake lights work and turn signals work.

The fuse is good.

I checked the ground between the cab and the flat bed and it was good even cleaned it. I also checked the ground at the lights them selves.

There is not voltage at the lights.

Could this be the switch?

Thanks,

start at one and and work your way back. or forward.
there is a plug at the rear, just under where the tailgate would be. start probing for voltage.

A power distribution center failure will cause symptoms like this. When ours went in our 04.5, one taillight would work and the opposite brake light. Then, the headlights only worked on one side.

Not saying for sure that it is your problem, but it could be something to look in to.

Looks like you have a relay that controls the Parking Lamps. Swap it with another of the relays that you know works and see if they work then.

Well, did you get it fixed?
