If the air mix door defect error is indicated, check as below.

1. Turn the ignition switch to ON position.

2. Measure the voltage between terminal P1 and P2 (approx. 12 V) and terminal a and b (approx. 5V).

3. If the voltage value is out of the specified value, check the related circuits for open.

4. If the circuits are in normal condition, replace the air mix door actuator assembly.

5. Connect the positive (+) and negative (-) cables of temporary power supply to the air mix door actuator. And,

connect the cable to each terminal (P1 and P2) in turn to check the motor operation and terminal output.

If the air conditioner does not turn on, check as below.

1. Remove the thermo AMP and measure the voltage between terminal No. 1 and 2 on the connector.

2. Check whether the output voltages (ON: approx. 12 V, off: 0 V).

3. If the voltage value is out of the specified value, replace the thermo AMP. If the circuit is in normal condition, check

as below.

4. Turn the ignition switch to ON position and turn on the air conditioner by pressing the A/C button. And measure the

voltage between terminal A12 and A11 on the FATC controller connector. (standard: approx. 12 V)

5. If the voltage value cannot be measured, check the circuit for open. If the measured value is within the specified

range, replace the FATC controller.

6) Thermo AMP

The thermo AMP outputs the compressor ON or OFF signal to ECU to prevent evaporator from freezing. The sensing part
of the thermistor is the evaporator fin contact type.

Removal and Installation of Sensors and Actuators

Preceding work: Disconnection of negative battery cable and removal of instrument panel

* Removal and installation

All removal and installation operations for sensors and actuators
have similar procedures.

1. Disconnect the corresponding connector (1).

2. Remove the mounting bolts for each mode actuator.

However, the thermo AMP and blower high speed relay can be
removed only after removing the air conditioner module.
