I have a 1996 buick century. The headlights will not come on and the brake lights dont work either. Also the Turn signals work but the hazards don't. I have check the bulbs and the fuses in the glove compartment. I don't know what else to check.

More than likely this is a module issue however, the way to figure this out is to pick one of the systems and diagnose that one until you fix it and if it fixes the other issues then that is a bonus but if not, we can move onto the next.

I am attaching the wiring diagrams for the headlights, so we basically need to start to find out if you have voltage coming out of the DRL module and if not, then check the switch and if there is voltage going in and not coming out then the module is the issue.

Please let me know what questions you have, and we can go from there.

Thanks
