Note. Before testing, check for HVAC DTCs (see GENERAL TROUBLESHOOTING INFORMATION ).

Scheme 12

1. Disconnect the 7P connector from the passenger's air mix control motor. NOTE: Incorrectly applying power and ground to the passenger's air mix control motor will damage it. Follow the instructions carefully.
2. Connect battery power to terminal No. 1 of the passenger's air mix control motor, and ground the terminal No. 2; the passenger's air mix control motor should run, and stop at Max Cool. If it doesn't, reverse the connections; the passenger's air mix control motor should run, and stop at Max Hot. When the passenger's air mix control motor stops running, disconnect 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, replace the passenger's air mix control motor (see «PASSENGER'S AIR MIX CONTROL MOTOR REPLACEMENT»(ref-333598-S11842915862009072100000) ). If the linkage or door sticks or binds, repair them as needed. If the passenger's 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 kohms.
5. Reconnect the passenger's 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. 5. Max Cool: about 1.5 V Max Hot: about 4.5 V
7. If either the resistance or voltage readings are not as specified, replace the passenger's air mix control motor (see «PASSENGER'S AIR MIX CONTROL MOTOR REPLACEMENT»(ref-333598-S11842915862009072100000) ).

Scheme 13

1. Remove the passenger's dashboard trim (see «PASSENGER'S DASHBOARD TRIM REMOVAL/INSTALLATION»(ref-333587-S33316179992009072100000) ) and the glove box (see «GLOVE BOX REMOVAL/INSTALLATION»(ref-333587-S08268234282009072100000) )
2. Disconnect the 7P connector (A) from the passenger's air mix control motor (B). Remove the self-tapping screws and the passenger's air mix control motor from the heater unit.
3. Install the motor in the reverse order of removal. Make sure the pin on the motor is properly engaged with the linkage. After installation, make sure the motor runs smoothly.

Scheme 14

1. Remove the audio unit, (see «AUDIO UNIT REMOVAL/INSTALLATION»(ref-333639-S09667756202009072100000) )
2. Remove the self-tapping screws, bolts, and the brackets (A).
3. Remove the self-tapping screws and separate the audio unit and the climate control unit (B).
4. Install the control unit in the reverse order of removal. After installation, operate the various functions to see whether works properly.
5. Run the self-diagnostic function to confirm that there are no problems in the system, (see «GENERAL TROUBLESHOOTING INFORMATION»(ref-333598-S32669866022009072100000) )
