Where is the flasher to fix a left turn signal that is stuck on?

Hey Tina==It is a burned out bulb that is the problem. Find out if it is front or rear and take the light assy off and change the bulb from the rear. If you told me what kind of car you have and model, I may could have been more specific. GoodluckJoe If you have a W126 and your left marker lights stay on, try twisting your headlight switch clockwise one click, to the "off" position.
