Sorry, forgot to mention that.. I already checked all the fuses. I wish it where that simple.
Is it possible for the third brake light to still come on if the brake light switch is broken. It doesnt seem possible. From checking the schematics again, it seems that after the brake light switch, there is a splice, and 2 wires break off. One wire goes to the third brake light, and the other goes to the turn signal switch. Is it possible that the turn signal switch could cause just the brake lights to go out if it went bad?

As soon as I have more time, I will follow the wires with a test light, and try to find where the "break" in the circuit is. Until then, anymore ideas would be appreciated.
