Air Door Actuator / Motor: Testing and Inspection
Air Mix Control Motor
Air Mix Control Motor Test
1. Disconnect the 7P connector from the air mix control motor.
2. Connect battery power to the No.1 terminal of the air mix control motor, and ground the No.2 terminal; the air mix control motor should run, and
stop at Max Cool. If it doesn't, reverse the connections; the air mix control motor should run, and stop at Max Hot. If the air mix control motor
does not run, 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.
-
If the linkage or door stick or bind, repair them as needed.
-
If the air mix control motor runs smoothly, go to step 3.
3. Measure the resistance between the No.5 and No.7 terminals. It should be between 4.2 k to 7.8 kOhm.
4. Reconnect the air mix control motor 7P connector, then turn the ignition switch ON(II).
5. Using the backprobe set, measure the voltage between the No.3 and No.5 terminals.
Max Cool-about 0.7 V
Max Hot-about 4.2V
6. If either the resistance or voltage readings are not as specified, replace the air mix control motor.
