Just to add to this one the brake switch under your brake pedal has two outputs one goes to the third brake light and other to the left and right brake blubs. Do you have a test light to test the power outputd of the brake switch?

Also do you have a tow wiring hooked up to the car?Has it ever had two wiring in it?I have seen the diodes in the tow wiring fail and cause the brake lights to become inop.
