Why is my Left Front light not working?
Since you brought up the emergency flashers it would be interesting to know if the left front light works ok with that switch on. If it does then the turn signal problem is most likely with that switch and not a ground problem for that light. Try cycling the switch a number of times to see if that helps clear the trouble.
Is there a turn signal when headlights are on?
That’s one issue…next problem is the no front left turn signal when headlights (and all the back lights that come on when you turn on headlights) are on. I plan to check if turn signal doesn’t come on if i just put parking lights on?
Why are my headlights not working when I turn them on?
You said you replaced it so there is either a bad connection to power to the socket or the ground side is bad and not making connection for some reason. Since the front signal doesn’t work when the headlights are on this would indicate a bad ground connection for the lights. Try cleaning the grounds to the chassis under the hood.

How to check the right front side light?
I removed both bulbs and swapped sides. The problem did not follow the bulbs and the fault remained. Next I removed the bulb from the left side and turned the ignition on as a sanity check on the faults. This yielded both Check Right Front Side Light AND Check Left Front Side Light.
Why is the left side of the turn signal not working?
This time, though, the left or right side of the signals doesn’t work. You may see the dash indicator lamps illuminating brightly, but the turn lights won’t flash. You may be dealing with bad bulbs or a fault between that side of the circuit and the turn signal switch itself.
Why is my right side parking light not working?
I replaced both left and right parking lamp bulbs from the parking lights in the bumper. Fault did not go away. When I turned on my headlights without the ignition on, my xenons were off and I found the additional parking lights in the headlight housing itself. Sure enough, right side the little accent light was out.
