Hey guys, I have a 2007 Yukon Denali, I’m having issues with my right side (passenger) tail light, when my headlights are on and brakes applied the entire tail light goes out, blinker doesn’t work, but blinks fast on the dashboard, when in reverse the reverse lights are on but once the brake is applied it goes out, this only happens on the right side tail light, also with the lights on or off that taillight is always dimmed…..I tried replacing all bulbs, replaced the harness, checked for broken wires, checked the ground wires, still no luck….any suggestions will help please

Welcome to the forum.

Follow the wiring along the frame to the junction block and check that and sometimes, you just have to replace the whole light housing.
