L.H.D.

Caution
•  If the lever position exceeds the operation range shown in the figure, the circuit in the actuator could be damaged. Always perform an actuator operation inspection with the lever movement within the range shown in the figure.

1.  Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)

2.  Remove the following parts:

(1)  Glove compartment (See GLOVE COMPARTMENT REMOVAL/INSTALLATION.)
(2)  Dashboard under cover (See DASHBOARD UNDER COVER REMOVAL/INSTALLATION.)

3.  Remove the air mix actuator. (See AIR MIX ACTUATOR REMOVAL/INSTALLATION [FULL-AUTO AIR CONDITIONER].)

4.  Apply battery positive voltage and connect the ground to the air mix actuator terminals as indicated in the table below and verify the operation condition.
