    Front turn signal doesn't flash. Swapped bulbs and did not fix the problem. running light is out but when you put all the lights on it works. Any idea why the signal flasher isnt working? Its a 2015 Tacoma

    Does it flash with the emergency Hazard switch?
    Are you sure you have it plugged in completely?
    Have you checked for voltage at the socket with the turn signal on?

    If the light works, and it's simply not flashing, that sounds like a relay issue.

    Try another bulb first, or look at the one you installed and make sure the element is complete.
    Also, you have to push pretty hard to make sure they are snapped into the socket. I'd recommend wearing a mechanics glove or leather glove on that hand when you verify. I was surprised how hard I had to push when I replaced mine last year.

    If you get voltage at the socket with the turn signal on and it doesn't blink it is most likely the flasher unit.

    to add to this thread...
    my 2012 left turn signal started rapidly flashing the other day. figured the bulb was bad. bought a new bulb and it still did it. However, if I press and hold the socket in to the bulb it starts working correctly. I hear and feel it snap into place but its like its just not getting a good connection. Should I use an anti-corrosion spray on it? Or what is the fix for this?
    Stock bulbs.
    I hope this is similar or the same issue OP is having, otherwise my apologies.

    High resistance connection between the bulb and the socket terminals causes rapid blinking. The truck thinks the bulb is blown. Either it isn't in completely, you have a defective socket or the incorrect type bulb. In that order of likelyhood.

    Inspect the socket for corrosion :notsure: If you see corrosion, you'd need to clean it up with a small file or sandpaper, then hose it down with Dexoit spray.

    If you don't see corrosion, the fingers in the bulb may be too spread out due to age. Simple enough to use a pocket screwdriver to pry them closer. I had to do this with my 3rd brake light bulbs when I replaced the LEDs in 2018.

    Welp. I went to check the bulb and it came out really easily. I didn’t push the bulb into the adaptor housing tight enough until it clicked. Now it works. carry on. Nothing to see here.

    Glad you got it figured out! Thanks for circling back.

    Yeah those take some force to get them fully inserted.
