Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello and welcome! Thank you for requesting me! Are you saying that the running lights dont work in the rear but do work in the front? Can I start by getting your VIN?
Thank you for the VIN. One minute while I pull a wiring diagram for you.
Ok, if the rear blinkers and brake lights work, then we know the ground for the system is good because they all share the same ground(s). The problem is going to be a power supply to the running lights in the rear (provided the sockets themselvs) are good. The wire I suspect that is bad (open or broken) is going to be the brown wire.
It is somwhere between the switch and the rear lights. You can trace the wire to find out where it is broken/open, or you can simply just run a new wire from the brown wire (coming from the switch) to the rear lights. Here is a wiring diagram of this circuit.
I am glad I can help!
