Passenger's Air Mix Control Motor Test - With Climate Control

1. Disconnect the 7P connector from the passenger's air mix control motor.
   Incorrectly applying power and ground to the passenger's air mix control motor will damage it. Follow the instructions carefully.

1. Connect battery power to the No. 1 terminal of the passenger's air mix control motor, and ground the No. 2 terminal; the passenger's air mix control motor should run,Cool side. If it doesn't, reverse the connections; the passenger's air mix control motor should run Hot side. If the passenger's air mix control motor does not run, remove it, then check the passenger's air mix control linkage and door for smooth movement.
   - If the linkage and door move smoothly, replace the passenger's air mix control motor.
   - If the linkage or door sticks or binds, repair them as needed.
   - If the passenger's air mix control motor runs smoothly, go to Step 3 .

1. Measure the resistance between the No. 5 and No. 7 terminals. It should be between 4.2 to 7.8 kΩ.

1. Reconnect the passenger's air mix control motor 7P connector, then turn the ignition switch ON (II).

1. Measure the voltage between the No. 3 and No. 5 terminals.

   Max Cool−about 1.5 V
   Max Hot−about 4.5 V

1. If either the resistance or voltage readings are not as specified, replace the passenger's air mix control motor.
