Center & Side Mounted Brake Lights not work, Turn Signals, Reverse Lights, and Night Time Running Lights are all Working. I have checked the bulbs, and fuses, and just replaced the brake light switch with no luck. Please Help!

Disconnect the brake switch......harness is an orange and a white wire.....orange is power in.....do you have Power with a test light on the orange wire? If no, check stop lamp fuse....
If you have power, then jumper the orange and white wires.....are your brake lights on? If no, go to center stop lamps.....yellow wire into the center stop lamp should be hot....is it? If no, you have an open circuit between center stop lamp and brake switch....if you have power, and bulb/socket is ok, then ground the red wire out of the socket.....if lights come on, then the ground is bad, or you have an open circuit....
If there was no power to the center stop lamps, there is a soldered joint, S205, that feeds all brake circuits.....that would be the first place to check.....unfortunately, I can't pinpoint the area it's in.....
