I have 95 S-10blazer 4-WD. My brake light are non functioning, all lights com on when light engaged, turn signals work,hazard light work, new bulbs, replaced switch at brake pedal. I just have no lights upon depressing brakes. Any Ideas?!

 

Nothing, including the 3rd brake light, lights up when the brake is pressed?

 

the brake lights as well as third light not functioning. Don't know where wiring harnes flows front brake switch any suggestions.

 

That would imply that the problem is with the brake switch itself as the CHMSL (center high mounted stop lamp) is not controlled by the multifunction switch as the lower lights (brake & turn) are.
