    For some reason my hazard lights dont work on my 2006 Volvo 780. Changed the headlight switch with the used one with no change.
    Regular L and R turn signal switch works good, just not the hazard lights.

    Do your t-sigs and hazards share one flasher or is there a separate flasher for each?

    If the blinkers work it's a wiring problem with the relay and fuses.

    There are separate fuses for turn signals and hazards.

    Check lcm for fault codes

    there are no separate fuses for every bulb. There is lcm with "smart" mosfets.

    No hazard light issue is usually related with light switch

    No codes in LCM and all fuses are good. I don't know what else could be but the switch?
