i have a 95 blazer and my third brake light is not working. ithas LED lights so i dont think it can be the bulbs right. does anyone know what is wrong and is the only way to replace it to buy a whole new light?
thanks in advance

Yes I think you have to replace the whole unit. Check to see if you have voltage going back to it when you hit the brakes first because often it is a bad connection and not the light itself. Use a test light or a volt meter. It gets it's power from the TCC Brake And Cruise Control Release Switch so you will have to trace it back if there is no voltage. Usually a white wire.Some GM models have a relay in between for the third brake light. Not sure about yours because I don't have a schematic for a 95.

 

Did u ever get your light to work I am having the same trouble. The light works but no voltage. I wonder if there is a fuse for just that light somewhere that i am no seeing
