no brake lights or 3rd brake light

[brianarmstrong]

I have a 2013 yukon I have no brake lights or high centre light in rear The cruze control works as it should and I can shut it off with the foot pedal The turn signals and 4 ways work fine ,I suspect the white wire from brake light switch to the turn signal switch is defective any thoughts on this

Pics of the truck, please.

Have you checked the fuses?

What voltage ate you getting at the brake switch output, when the brake pedal is depressed?

Has the light outage been confirmed while the vehicle is running and not just parked? The brake lights won't come on unless the vehicle is running
