The Hazard lights and the brake lights on my '04 Vectra quit working. Turn signals and tailights work fine.

No audible 'click' when Hazard switch is on.

Center brake light bar works as it should, but the right & left brake/tail/signal lights are dead when brakes are applied, but they work ok as taillights and as turn signals.

Can anyone give me a clue where I might find a breaker or a fuse that controls this circuit?

Thanks.

Found my Hazard problem! Opened up the chasssis breaker panel and found lots of goodies hidden back there, including the Hazard flasher which had been sitting in some trapped rainwater and had corroded. Replaced it and Hazards work fine. Still no brake lights, tho.
Does anyone know what/where the brake light circuit diodes look like/located?

Is this on a Freightliner chassis? If you do not get a response from a member that can help, call the mfg of chassis. Good luck and pass on the info so others can be helped. Thanks.

On some vehicles, the turn signal switch opens off the brake signal to let the turn function operate. This could be the problem. There may also be two feeds off the brake switch, one for the third light, the other to the turn signal switch. Check both feeds for 12V with brake applied. You may also find the cruise switch located with the brake switch, don't follow the cruise leads.
