1. Disconnect the 7P connector from the driver's air mix control motor.

NOTICE
Incorrectly applying power and ground to the passenger's air mix control motor will damage it. Follow the instructions carefully.


2. Connect battery power to terminal No. 1 of the passenger's air mix control motor, and ground terminal No. 2 ; the passenger's air mix control motor should run, and stop at Max Cool. If it does not, reverse the connections; the passenger's air mix control motor should run, and stop at Max Hot. When the passenger's air mix control motor stops running, disconnect battery power immediately.

- If the passenger's air mix control motor runs smoothly, go to step 4.

4. Measure the resistance between terminals No. 5 and No. 7 of the passenger's air mix control motor. It should be between 4.2 and 7.8 kOhms.

5. Reconnect the air mix control motor 7P connector, then turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.

6. Using the backprobe set (07SAZ-001000A), measure the voltage between terminals No. 3 and No. 5.
