Honda Accord: Air Mix Control Motor Test
NOTE: Before testing the motor, check for HVAC DTCs (see page 21-9).
1. Disconnect the 7P connector from the air mix control motor.
Incorrectly applying power and ground to the air mix control motor will damage it. Follow the instructions carefully.
2. Connect battery power to terminal No. 1 of the air mix control motor, and ground terminal No. 2; the air mix control motor should run, and stop at Max Hot. If it doesn't, reverse the connections; the air mix control motor should run, and stop at Max Cool. When the air mix control motor stops running, disconnect battery power immediately.

3. If the air mix control motor did not run in step 2, remove it, then check the air mix control linkage and.
door for smooth movement.
• If the linkage and door move smoothly, replace the air mix control motor (see page 21-60).
• If the linkage or door sticks or binds, repair them as needed.
• If the air mix control motor runs smoothly, go to step 4.
4. Measure the resistance between terminals No. 5 and No. 7. It should be between 4.2 to 7.8 kO.
5. Reconnect the air mix control motor 7P connector, then turn the ignition switch to ON (II).
6. Using the backprobe set, measure the voltage between terminals No. 3 and No. 7 of the 7P connector.
Max Cool; About 0.5 V
Max Hot; About 4.5 V
7. If either the resistance or the voltage readings are not as specified, replace the air mix control motor (see page 21-60).
