Heater motor with front panel removed
Rear blower parts
Attention! When performing work on the heater, turn the ignition key to the LOCK position, disconnect the battery from the mass and start work no earlier than after 2 minutes.
Examination
1. On cars "Toyota 4 Runner/ Hilux/ Surf" the heater blower unit is mounted under the front panel and under the passenger seat. If the fan fails, check the fuse and the condition of the contacts and wires.
2. Check motor connector for battery voltage (turn on the ignition and turn the fan knob to the ON position).
3. If voltage is present, then connect the connector and connect pin 2 to ground. If the fan does not turn on, the motor may be defective. In this case, connect the motor leads to power and ground through wires protected by fuses. If the motor does not turn on, it must be replaced.
4. If the motor is good, then check the resistor or switch.
Replacement
1. Disconnect the connector, unscrew the 3 screws and remove the blower unit from the casing.
2. To access the rear airflow unit, remove the passenger seat.
