front left blinker bulb replacement
how does one change the bulb for the left front turn signal?
This video link shows you how to change a burnt out front turn signal bulb on your 2013 Toyota 4Runner. If the turn signal (also known as a blinker or flasher) blinks rapidly or doesn't blink at all / stays stuck when engaged, this is your 4Runner's way of telling you that a turn signal bulb is burnt out. Troubleshooting for burnt out turn signal bulbs in your 4Runner is relatively easy - turn your hazard lights on and check the front of your 4Runner and then the back, whichever side is not illuminating is the side with the burnt out bulb. We recommend that you change both the driver and passenger side bulbs at the same time as they get dimmer over time and if one is out, then the other one is likely to burn out soon.
When changing the turn signal bulb in your 4Runner, be careful not to touch the glass portion of the bulb with your fingers as this will cause the bulb to burn out prematurely.
I posted a link for a repair guide but the ifixit robot marked it as spam. However all you have to do is search on google for how to change a turn signal on a 2010-Present Toyota 4Runner.
