Fan Control Lever (Fan Switch)

Fan Control Lever (Fan Switch) Diagnosis
Current flows to the blower motor through the heater relay (X-1) to activate the rotation of the blower motor by turning "ON" the fan control knob (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 table, refer to Inspection.
