    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.

    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:

    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.

    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
