2011 tahoe brake lights

Chevy Tahoe 2011. Passenger and driver brake lights not working. Hatch does work. All blinkers, hazards, and running lights work. The bulbs are good. I replaced the brake switch. It fixed the cruise control but the brake lights still don’t work. I checked the fuses and all look okay. Don’t know where else to look and need some help.

Did you change the bulb?

Just because it “looks” okay doesn’t mean it’s good.

The problem is most likely with the multi-function switch.

The brake lights circuit passes thru this switch.

Common problem with GM vehicles.
