A multifunction switch, or combination switch, is usually mounted to the left or right of the steering wheel, with many vehicles having one on each side. These switches control several functions, with the most common being the turn signals, headlights, washer fluid, and windshield wipers.
The multifunction switch is an integral and frequently used component while driving. If there is a problem with the switch, the driver may be unable to adequately control the turn signals, headlights, or windshield wipers. These are all important safety features that can lead to dangerous driving situations if not functioning properly.
If you are encountering problems operating the turn signals, headlights, or windshield wipers, it may be time to replace the vehicle’s multifunction switch.
