My brake lights stopped working...the brake light switch on the pedal is getting voltage and changing when the pedal is pressed. there is no voltage at the brake lights though. i traced the wire using a diagram and an hour later came up with nothing. the break light circuit is a part of the abs circuit, the wire goes from the break switch to no mans land under the dash i also noticed that the circuit goes through the bulb failure sensor by the relays behind the ash tray but if that was the problem i would think that more than just the break lights woudl not work. if any one has any suggestions please reply.

 

Remove and open the Bulb failure relay and inspect.
I will bet your problem is the relay.
