3rd Brake Light does not work.
 

no power going to the wires when pedal is pressed.

All other lights/brake lights work fine. We can rule out the switch on the brake pedal.

anyone have a wiring diagram? Is there a seperate fuse than the other lights back there?

Looking it up..keep your spud on... :lol:

Hans - which car?
Bill - what year is the diagram for?

I'm assuming 98 on both. Hans hasnt messed with that 93 or posted about it lately. ;)

Mike.....he's talking the 98, the diagram is 98 ;)

OK - just wanted to make sure. Looks like all the brake lights get power from the same source. Some of the earier years had 2 contacts in the brake switch.

what is P408?

A rubber grommet

IIRC it's probably on the driverside by the wheel well where the wires are routed through the grommet into the trunk.
