Fan Control Lever (Fan Switch) Diagnosis

FAN CONTROL LEVER (FAN SWITCH) DIAGNOSIS

Blower And Controls:

Current flows to the blower motor through the heater relay (X-6) to activate the rotation of the blower motor by turning "ON" the fan control lever (fan switch).

Blower motor speed is controlled in stages by the resistor, by operating the switch from "LOW" to "HIGH". For the inspection of the relays, switches and units in each flowchart, refer to Testing and Inspection for the component.
