NO >> Replace blower motor. Refer to VTL-15, "Removal and Installation (LHD models)" or VTL-16, "Removal and Installation (RHD models)".
3.CHECK BLOWER MOTOR
Check that blower motor turns smoothly.
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace blower motor. Refer to VTL-15, "Removal and Installation (LHD models)" or VTL-16, "Removal and Installation (RHD models)".
Component Inspection (Blower Relay)
1.CHECK BLOWER RELAY
1. Remove blower relay. Refer to PG-22, "Fuse, Connector and Terminal Arrangement".
2. Check continuity between blower relay terminal 3 and 5 when the voltage is supplied between terminal 1 and 2.
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace blower relay.
Component Inspection (Blower Fan Resistor)
