Note

•  When inspecting the evaporator temperature sensor, inspect it when it is installed to the A/C unit.

1.  Switch the ignition OFF (LOCK).

2.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)

3.  Remove the following parts.

(1)  Glove compartment (See GLOVE COMPARTMENT REMOVAL/INSTALLATION.)

(2)  Side wall (passenger-side). (See SIDE WALL REMOVAL/INSTALLATION.)

4.  Connect the negative battery terminal. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)

5.  Perform the following procedure so that the ambient temperature of the evaporator temperature sensor is close to the cabin temperature.

•  Switch the ignition ON (engine on).

•  Set airflow volume to maximum.

•  Set the temperature to MAX COLD.

•  Turn the A/C switch off.

•  Set the air intake mode to REC.

•  Fully close all the doors and the door glass.
