The blower motor switch is part of the heating and air conditioning controls. The fan setting you choose determines the speed the blower motor runs at, which sets how much air moves through the vents for heating, cooling and defrosting.
Signs this part may need replacing: the blower does not run on one or more fan settings, works only intermittently, or does not respond when you move the switch. The blower motor, blower resistor and wiring can cause similar symptoms, so diagnose the cause before you replace the switch. If the switch is the cause, the HS-521 replaces it.
