The break lights on my 95 silverado are not working. The parking lights and blinkers and hazard are working and the third break light is working. I also have a break box for my trailer and it lights up. I checked the wiring at the wiring harness at the rear bumper with a test light and Im not getting anything. I checked the fuse at the fuse box on the drivers side dash fuse box and it was good. When I have the hazard lights on and hit the break pedal they keep on flashing and dont stop like they should. Any ideas how to trouble shoot. THANKS

 

Bad pedal switch?

 

I may check that tomorrow, but if it is the switch would the third break light be working like mine. Thanks
