    Hello All

    I have a 2001 FL112 with a C12. I'm pulling my hair out trying track down my passenger side rear tun signal source. Right now The main wire harness feeding the tail light sends power to the brake lights (Both sides) but does not flash (pass side) when the turn is on. The front signals work and flash as well as the dash but no flash in the rear. I'm using a meter and a test light...

    On a secondary trailer plug (Tucked under the truck at the rear) I get a turn signal but no brake light power.:biggrin_25510:

    Here is a picture of the plug that has turn signal power but no break lights...

    Does anyone know if the front and rear turns are on different circuits?


    So the main wire harness work for brake lights and driver turn but not passenger side turn and the plug only work for turn...



    Anyone out there that can help???

    Thanks a ton!

    Take the back off the plug and insp. wires for tightness.

    Thanks baha!

    I have checked it, and everything is sealed up tight and clean on the plug. I was hoping there was a flasher relay for the rear turn signals that was not working.

    Going to put a toner on the wire and try to trace it back to the front of the truck.

    I was hoping someone was going to say "Sure, there is a relay for each rear turn signal, in this spot!" HAHAHA, so much for that.

    Thanks for the help.:biggrin_25519:

    A bad turn signal switch can cause that
