Tail lights not working on Silverado 2012 LTZ

Recommended Posts

Fuses, main wiring harness at the rear of the truck. Should be under tail gate behind the bumper. Connects main harness to the tail light harness. Make sure connection is good and clean.

Also, check all the bulbs. I have seen bulbs fail each other an all fail within a close enough time that they were all out. Start with the simple stuff.

Once all the bulbs are confirmed good, work your way under the bumper and follow the harness to the control junction and clean all connectors. You can test all wiring and fuse while confirming wiring is not damaged. If you drive off-road a branch could reach up and grab the wires.
