Brake lights on my 2005 Tahoe don't work.

[Mmorreale]

My brake lights don't work on my 05 Tahoe but all others do. I have checked all the fuses n bulbs, changed the brake light switch and the rear lights circuit board. They still don't work, not even the third brake light. I'm getting 12 volts at the circuit board but no brake lights. Help!

Did you ever resolve your issue? Curious of the solution as I have the same problem after checking bulbs and fuses and changing brake light switch.

Thanks.

Nevermind. New brake switch was bad (thanks AutoZone!). Cleaned contacts of old switch and it works great!

Mmorreale, it could be a 20 amp fuse under the hood, it says veh. stop.
That one blew on my 2002 yukon xl.
I didn´t have brake lights either incl. third.
