brake light problem

[GONEFISHINTODAY]

brake lights don't work.

Turn signals work.
Tail light work.

replaced brake switch still no brake light.

any ideas? guessing an open wire to the switch. are these switches making contact to gnd or to battery?

I don't have wiring diag with me.

thanks

1, did you check your fuses under the cab and under the hood?

I bet that you have one or two fuses blown. This same scenario happened to my Son yesterday in his truck. Found out that two fuses went south.
