Still trying to figure this truck out. 3rd brake light does not work, no cab lights on 3rd brake light. Nothing dings or chimes when I open the doors or put the key in the ignition nor does the dome light come on. Hazards: only right side flashes. Checked fuses. Anything else i can do? dont wana rip out all the wiring. Bulbs are good. Are these connected issues? any help would be great. Thanks

 

Sounds like your door pressure switch isn't registering that the door is opening, or, has an issue with the wires. As for the brake and hazards, did the PO mess with the wiring or something?

 

Yeah I guess I just need to chase wires. There's a plow on it, there was a dump body and a salt spreader so there's all sorts of wiring. I didn't think it would mess with those specific things tho
