Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello I will help you with your question,
Can you go under the rear of the truck near the spare tire and check the junction box there? Follow the harness from the rear lights forward to the box. Check the light blue wires with the 3 brake light on, if you have power into the junction but not out then the junction box needs to be replaced. Check the VEH STOP fuse as well
Please let me know what you find and how I can help
So what did you find and what more did you do?
Do you have 12 volts on the VEH STOP fuse at BOTH of the test points on the back of the fuse?
Please let me know what you see so I can help
