Reset Methods

1. After replacing the air mix actuator, make sure to complete the following reset procedure.

Automatic reset

1. Disconnect the negative battery cable, and then reconnect it. (AUTO switch indicator light flashes.)

Controlled reset

1. Switch to on-board diagnostic mode. (See «DIAGNOSTIC TROUBLE CODE NUMBER INSPECTION»(ref-193869-S18766886632005092600000) .)
2. While in present failure indication mode, press the DEFROSTER switch for 3 seconds or more. (AUTO switch indicator light flashes.)

Scheme 130

1. Disconnect the negative battery cable.
2. Remove the glove compartment.
3. Remove in the order indicated in the table. AIRFLOW MODE ACTUATOR REMOVAL/INSTALLATION 1 Airflow Mode Actuator Connector 2 Air flow Mode Actuator
4. Install in the reverse order of removal.

Scheme 131

Scheme 132

Scheme 133

Scheme 134

1. Connect battery positive voltage to terminal E or F and ground to terminal F or E of the airflow mode actuator.
2. Verify that the airflow mode actuator operates as shown see scheme 11. If not as specified, replace the airflow mode actuator.
3. Verify that the resistance between the terminals of the airflow mode actuator is as shown in the (Scheme 131). If not as specified, replace the airflow mode actuator.

Scheme 135

1. Turn the fan switch to OFF.
2. Turn the mode dial to VENT.
3. Turn the ignition switch to ON position. (engine ON)
4. Turn the fan switch 4th position.
5. Turn the mode dial from VENT to DEFROSTER.
6. Verify that the airflow mode actuator moves smoothly. If not as specified, inspect the airflow mode main link and sub link for clogging and deformity. If the actuator cannot move at all, go to voltage inspection.

Scheme 136

Scheme 137

1. Disconnect the airflow mode actuator connector.
2. Turn the ignition switch to ON position. (engine OFF)
3. Verify that the voltage between the terminals of airflow mode actuator (harness-side) is (Scheme 133) If not as specified, perform the harness inspection and mode switch inspection. (See «CLIMATE CONTROL UNIT INSPECTION»(ref-193873-S41873686912005092600000).) If as specified, replace the airflow mode actuator.

Scheme 138

1. Disconnect the negative battery cable.
2. Remove in the order indicated in the table. BLOWER MOTOR REMOVAL/INSTALLATION 1 Blower Motor Connector 2 Blower Motor
3. Install in the reverse order of removal.

Scheme 139

1. Connect battery positive voltage to terminal B and ground to terminal A of the blower motor and verify its operation. If not as specified, replace the blower motor.

Scheme 140

1. Disconnect the negative battery cable.
2. Remove the glove compartment.
3. Remove in the order indicated in the table. RESISTOR REMOVAL/INSTALLATION 1 Resistor Connector 2 Resistor
4. Install in the reverse order of removal.

Scheme 141

Scheme 142

1. Verify that the resistance between the terminals of the resistor is (Scheme 136) If not as specified, replace the resistor.
