Troubleshooting Trailer Wiring that Doesn't Work with 2008 Silverado
Updated 07/25/2019 | Published 07/24/2019
Question:
I changed the 1,3,10, and 25 fuses in my 2008 2500 Silverado and the lights still don’t work? I checked the trailer in a different vehicle and the trailer lights work fine, so it has to be mine. Any advice? Thanx!

Expert Reply:
Have you tried cleaning the pins of the trailer connector on your truck? Most likely you have a dirty pin that has some corrosion on it that all you'd need to do is clean with some sandpaper and that will get you going.
Check also the back of the connector for any corrosion or cut wires there and fix as needed.
