I have an 03 coupe with 03 headlights. The drivers side turn signal will randomly not come on when I turn the headlights on. The turn signal still works when I'm turning, but it won't stay constantly on. It happens randomly about once or twice a day/night. Nothing in common to indicate that it is triggered by something. Anyone know what the issue could be? Is the bulb going out or a short in the wiring? Thanks for your help.

 

Check the bulb for a loose connection and/or bad bulb by pulling the bulb from inside the fenderwell area.
