Brake light issue

This sounds very similar to the problem I have going on. I have no turn signals in the rear and no brake lights. I do have flashers and all the lights on the front work the way they're supposed to.

All my fuses are good as is my turn signal switch, which I pulled apart, cleaned all the contacts and put a little dielectric grease on the contacts.

Right now I have the dash pulled half way out trying to trace out the wiring, but any help you guys can give would be appreciated.
