    Hi,

    My RR turn signal/stop lamp is out, tried new LED and still nothing.

    I'm having trouble locating the turn signal or stop lamp fuses. Tried the PDC under the hood, and under the dash. Are they under the bunk for some reason?

    I also manually checked every fuse under the bunk, all good there.

    So I was going to attach diagram, but to large to attach. PM me and I can email it to you if you need it. Took picture of fuse chart, but that was to big to attach also!!! Fuse for right turn /stop rear is G3 which is in cab PDC (fuse panel) G3 also powers left turn front/side, so if those are working your fuse is good. If both turn and taillight aren't working, I would be checking for a broken ground wire. All lights share same ground on white wire, just spliced for each light.
     
    Vulpine93 Thanks this.
