Air Door Actuator / Motor: Testing and Inspection
Air Mix Control Motor Test
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.
Mode Control Motor Test
Mode Control Motor Test
1. Disconnect the 7P connector from the mode control motor.
2. Connect battery power to the No.1 terminal of the mode control motor, and ground the No.2 terminal; the mode control motor should run
smoothly, and stop at Defrost. If it doesn't, reverse the connections; the mode control motor should run smoothly, and stop at Vent. When the
mode control motor stops running, disconnect battery power immediately.
3. If the mode control motor does not run in step 2, remove it, then check the mode control linkage and doors for smooth movement.
-
If the linkage and doors move smoothly, replace the mode control motor.
-
If the linkage or doors stick or bind, repair them as needed.
-
If the mode control motor runs smoothly, go to step 4.
4. Use a digital multimeter with an output of 1 mA or less at the 20 kOhm, range. With the mode control motor running as in step 2, check for
continuity between the No.3, 4, 5, and 6 terminals and the No.7 terminal individually. There should be continuity for a moment at each terminal.
5. If there is no continuity for a moment at each terminal, replace the mode control motor.
