    2021 Toyota tundra no electrical modifications. Driver side high beam quit working. Passenger side low and high beam work fine. I replaced the bulb on the driver side same problem. Low beam works fine high beam not working. I am confused. I think if it were a relay or a fuse issue, both lights would be doing the same thing. In the advice would be appreciated

    Will be curious n the fix for this. Replacing the bulb made sense and agree that’s a weird result. Have you had the Toyota recall done on the headlights? Toyota cuts the wires and install a relay on each side I believe, maybe they messed up.

    I wanna say there are fuses for each side low and high in the fuse box under the hood. Have you checked those?

    I have checked all of those and did not see that there were separate fuses for right and left but all the fuses I checked looked fine

    I’d suggest checking them with a multimeter, not just visually. And if you haven’t had the halogen harness recall done (if applicable to ‘21) do that asap.

    Actually that’s a good question are these halogen or LED?

    When “swapping bulbs” was mentioned, I assumed halogen

    Same just confirming and that they are halogens and not LED bulbs.
