Low beams not working

    I was doing some work on my 02 Tundra this afternoon and when I finished up my headlights weren’t working correctly. Not sure if I bumped something or if it’s just coincidence.

    Basically it’s just the headlight function on the switch that isn’t working. Running lights work, high beam flash works but the low beams won’t come on, the fog lights don’t come on and full time high beam won’t come on.

    I’ve checked the bulbs, associated fuses and relays and checked for loose wires but I can’t find the culprit. Any suggestions? Did my switch somehow go bad?

    The work I was doing was under the dash but completely separate and unrelated to the headlight circuitry

    Function before sparkle.
    You’re in the 2022 and newer section. Is your truck a 2022 or 2002?

    Oh, sorry, I thought I was in the correct section but I guess my fat thumbs had other ideas.

    I’ll repost in the correct area. Admin please remove

    All good. Just a sign from your thumbs you need to upgrade to a Gen3. The light at the end of the tunnel!
