As a few of you know, I now have a 2005 Yukon SLT 2WD. The 3rd brake light didn't work when I bought it, so I thought it might've been the 3rd brake light itself. Well I just got a new 3rd brake light and installed it and it still didn't work. I checked the fuse box but I couldn't find a fuse for it. Any input or advice would be greatly appreciated.

Also the wiring that goes from the body into the lift gate gets corroded and frays. If you don’t see anything obvious use a test light to see if you’re getting power.

On my '04 there are several fuses in the in-cab driver's side fusebox. Open the driver's door and it's on the end of the dash. If yours is the same check the one boxed in red:

My dad found the fuse last night and checked it and said it wasn't blown so when I get out of school today I'm gonna check to see if I'm getting voltage to the load itself and go from there

Found out the problem. When I was putting it in I didn't realize that I bent a prong in the connector. Straightened it out and the 3rd brake light worked perfect
