    Hey I just wanted to ask for some advice . I got a 2018 tacoma and the low beams quit working. Bulbs are good , fuses and relays are good . I swapped the low beam relay to high beam and that relay was good. There is no power coming into the low beam relay at all . All fuses looked fine and had power coming in to them. I'm thinking maybe the headlight stalk switch on steering column ? Everything works fine , even the dash lights saying lights are on. The low beams just won't fire on. If anyone has any knowledge in this or may know what it is. Please let me know ! Thanks

    If the dash says they're on then it's not the switch
    Pull the fuse and make sure the contact tab didn't brake off and also that the contacts are in the block
    with a test light or multimeter check that there is power at the relay for both the control and the power also check the control ground pin to ground has continuity
    look for rodent damage to the wiring harness

    Do your low beams activate when your high beams are on? The low beams should be on when the high beams are on too.

    I will double check fuses and all again . The relay isn't clicking for low beams. And checked the block it plugs into and no power even coming into relay. Relay seems to be fine since it is same as high beam relay. I tried it in its spot and worked fine.
