Bit confused here. Left front turn signal and runnin light is not workin. Rear turn signal flashes really fast. When I turn on my emergency flashers, every light flashes normal except left front. Nothin there.

Bulb and fuses are fine. Replaced right bulb with left one. Same results. When I turn my lights off auto onto the on position, runnin light will come on but is dull. 2022 sr model.

Thanks for any help.

Sounds like a ground issue, possibly through the switch.

Did you replace the flasher that could be weak.

these new trucks have a general electric module and some times a relay but seldom the old style flasher can we used to have.

a meter at the lamp and work back
it would really help to have a wiring diagram

figure out where you have power and don't , where you have ground and don't

I am not a toyota guy so I dont' know how they do their cabling

My Tacoma did that and it was a faulty socket.

My wifes car does that, last time I took the lamp out and reversed it, works like a charm now...weird...
