3rd Brake Light NOT Working?

[fennsz]

I have a 2005 Yukon and my 3rd brake light is out...do I have to replace the whole assembly to get that working again? I didn't see that it was just a bulb?

thanks

Yes, the whole thing. They are LED's. Sorry.

Be sure to check your fuses before you go replacing the light, I believe that the 3rd brake light is on its own fuse instead of sharing the main brake light fuse. Also, you should be able to use a test light and see if you are getting voltage to the 3rd brake light when you push down on the brake pedal.

THANK YOU

Thanks soo much, you guys are awesome! I will first check fuses and power, but if that all checks out I will know what I am in for.

if you install the led tails wrong it'll trip the fuses, if you install them wrong they wont work. So make sure you got them in correctly.
