- Faulty hazard switch:
The hazard switch is responsible for activating the hazard lights. If it is faulty, it may not be able to send a signal to the turn signal relay, which would prevent the hazard lights from working.
- Faulty turn signal relay:
The turn signal relay is responsible for controlling the flashing of the turn signals and hazard lights. If it is faulty, it may not be able to send power to the hazard lights, even though the turn signals are working properly.
- Faulty wiring:
The wiring that connects the hazard switch and turn signal relay to the hazard lights may be damaged or disconnected. This would prevent the hazard lights from working, even if the hazard switch and turn signal relay are functioning properly.
- Faulty hazard light bulbs:
The hazard light bulbs may be burnt out or have a poor connection. This would prevent the hazard lights from illuminating, even if the hazard switch, turn signal relay, and wiring are all functioning properly.
