If your Ford Galaxy’s headlights don’t work, it may be because the headlight switch is broken. With this switch, you can turn on and off your low beam and high beam headlights, as well as dim or brighten them. On the driver’s side of the Ford Galaxy, the headlight switch is next to the left-most air vent. To change the headlight switch, you don’t need any special tools. You should plan to spend about 30 minutes on the job as a whole.
