NOTE: Before testing the motor, check for climate control DTCs.

2. Passenger's Air Mix Control Motor - Test
1.
Disconnect the passenger's air mix control motor connector.

Incorrectly applying power and ground to the passenger's air mix control motor will damage it. Follow the instructions carefully.
2.
Connect 12 volt battery power to terminal No. 6 of the passenger's air mix control motor, and ground terminal No. 7; the passenger's air mix control motor should run, and stop at MAX HOT. If it does not, reverse the connections; the passenger's air mix control motor should run, and stop at MAX COOL. When the passenger's air mix control motor stops running, disconnect 12 volt battery power immediately.
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, go to step 4.
If the linkage or door sticks or binds, repair them as needed.
4.
Measure the resistance between terminals No. 1 and No. 3. It should be between 4.2 to 7.8 k?.
5.
Reconnect the passenger's air mix control motor connector.
6.
Turn the vehicle to the ON mode.
7.
Measure the voltage between terminals No. 2 and No. 3.
MAX COOL:
About 0.5 V
MAX HOT:
About 4.0 V
8.
If either the resistance or the voltage readings are not as specified, replace the passenger's air mix control motor.
