Left turn signal is not working. Changed Bulb but still does not work. Right turn signal is working.... Any ideas?

What is year--make--model?
Neither the front or rear right turn work? If that is correct, I'd check the turn signal switch and wiring circuit.

was the correct bulb used? this sounds like a single function bulb was used NOT the bulb that will light with the headlights and ALso produce turn singles

have you checked the bulbs front and back. to see if they work, bulb check. then it sounds like you might have a bad signal flasher that only works the left side and not the right side. or if a bulb at the front or the rear gets bright but not the opposite bulb on the same side then you may just have a bad bulb or socket or power to the socket when doing the bulb check.

Left turn sounds like bad bulb.Hazards could be the switch or flasher.

Fast flashing dash signals mean there is a bulb issue-DEFINATELY!

either wrong signal bulb or short in left turn signal wiring if both left signal lamps not working.if only one of left turn signal dont work could have corroded bulb socket spray a little electronic cleaner in bulb sockets see if left signal work.

Could be the switch itself. Pretty easy to replace the whole turn signal switch. I've had the flashers go out also on mine, but mine ended up being the switch. I grabbed one from a recycling yard, cost me less than $20.

What you speak of as to the left blinker doesn't flash, yet the instrument cluster shows the green arrow (to the left), and yet that and the left turn signal lights do not flash, appears to be a simple burned out bulb. If one of your left turn signal bulbs are burnt out, then the #552 Flasher Unit in your fuse box is NOT the cause. It's the "Amperage" not being correct to the flasher unit. Place the parking brake on and start your vehicle. Put the left turn signal on and check to see ALL the bulbs are illuminated for the left turn signal. If you find one bulb that is not illuminated, then replace the bulb. It should be an 1157 bulb, but in the front it could be a 1157 Amber bulb dependent on whether your turn signal lens is clear or yellow.

If you still have difficulty finding the dead bulb, turn on the right turn signal and see which bulbs are illuminated and this will give you an idea as to which bulb on the left side isn't working, or turn on your Emergency Flashers which will turn on both the left and right side lamps and see which bulb is not lit up.

I hope this Helps,
