Air Door Actuator / Motor: Testing and Inspection
Passenger's Air Mix Control Motor
Passenger's Air Mix Control Motor Test
NOTE: Before testing, check for HVAC DTCs.
1. Disconnect the 5P connector from the passenger's air mix control motor.
Incorrectly applying power and ground to the passenger's air mix control motor will damage ii. Follow the instructions carefully.
2. 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, and stop at Max Hot. If it doesn't, reverse the connections; the passenger's air mix control motor should run, and stop at Max
Cool.
3. If the passenger's air mix control motor did not run in step 2, 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, repal' them as needed.
-
If the passenger's air mix control motor runs smoothly, go to step 4.
4. Measure the resistance between the No.4 and No.5 terminals. It should be between 4.2 to 7.8 kOhm.
5. Reconnect the passenger's air mix control motor 5P connector, then turn the ignition switch ON (II).
6. Using the backprobe set, measure the voltage between the No.3 and No.5 terminals.
Max Cool about 1.0 V
Max Hot-about 4.0 V
7. If either the resistance or voltage readings are lot as specified, replace the passenger's air mix control motor.
