Brake lights and rear deck light do not work on 1991 Lexus ls400. I checked all fuses,bulbs, and Brake switch and they are fine. Help? Brake light switch was replaced and didn't solve problem. Also the brake lock out system works fine. All other car light work including the tail lights which are also the brake lights when brake pedal pressed.

Need a faster answer?
Have you probed the tail/brake lamp socket to see if power is there or you just assume it is? also make sure the ground is good for the brake lights Do that if not done already and let me know.
