Brake Lights aren't Working and I've tried everything (I think)

Jrod2330

Tail lights work, blinkers work but all brake lights are out. I changed out bulbs, brake switch, checked fuse, and ran a scan and nothing showed up. Searched online and in forums and haven't found anything helpful yet.

Only thing maybe intriguing..when I depress the brake switch, there is a click from somewhere behind the steering wheel in the dash.

Any other ideas?

That's probably the shift interlock solenoid that you can hear when you push the brake pedal. If so that's good it tells us where you have power up to a point. Looking at the schematic, is the high mount brake light working or not? The high mount brake lamp circuit splits off from the White/Black wire before it goes to a component in the right rear cargo area.

In the right side of the cargo area of the vehicle there is a component called the brake light failure sensor. Power comes from the brake light switch to pin #6 White/Black into that unit and leaves to go to the brake lights on Pin #2 Green wire.
