Automatic Temperature Control Sensor Removal:

2. Remove the two mounting screws from the sensor assembly.
3. Remove the control cable housing-to-sensor attaching screw.
4. Disconnect the cable end loop from the lever arm and remove the cable from the sensor assembly.

NOTE: Secure the control cable with tape or service wire to prevent it from falling from sight behind the instrument panel.

5. Disconnect the sensor vacuum harness from the servo vacuum harness.
6. Remove the ambient air hose from the end of the sensor assembly by rotating the sensor assembly in a clockwise direction.
7. Remove the sensor assembly from the vehicle.

Installation
1. Connect the ambient air hose to the sensor by turning it in a counterclockwise direction.
2. Route and connect the vacuum harness connector to the jumper line connector and ensure the locking tab is snapped onto jumper line connector.
