What else can you check if flasher and hazards lights are out fuses and relay working?

If the flasher and hazard lights are out despite the fuses and relays being functional, you should check the bulbs for any burnout or damage, as well as the wiring and connections for corrosion or loose connections. Additionally, inspect the turn signal switch in the steering column, as it may be faulty. Finally, ensure that the vehicle's battery is providing sufficient voltage, as low power can affect the operation of the lights.
