1993 Buick Skylark Turn Signals

Turn your hazard lights on and check if all lights are working. If a bulb dosn't light up replace it. All bulb need to light or turn signals won't work on side that is burnt out. If all lights are working, try changing out flasher relay. If that dosn't work, have turn turn signal switch check. Thay may call it a multi function switch for that year.
