4. If required, remove the three screws that secure the rear A/C-heater control to the bezel and remove the control from the bezel.

INSTALLATION
1. If required, position the rear A/C-heater control onto the rear A/C- heater control housing or bezel (depending on application).
2. Install the three screws that secure the rear A/C-heater control to the housing or bezel. Tighten the screws to 2 N.m (17 in. lbs.).
3. Position the rear A/C-heater control to the headliner or overhead rail (depending on application) and connect the wire harness connector(s) to the rear of the control.
4. If headliner mounted, insert the locator tabs on the back of the rear A/C-heater control bezel over the forward edge of the opening in the headliner and using hand pressure, push the rear A/C-heater control bezel into the headliner until the two retaining clips fully seat.
5. If overhead rail mounted, position the top of the rear A/C-heater control housing over the overhead rails and using hand pressure, push the rear A/C-heater control housing onto the overhead rails until the retaining clips fully seat.
6. Reconnect the negative battery cable.
7. Using the DRB-III(R) scan tool, reset the Rear Temperature Selector calibration values.
8. Verify that the Actuator Calibration of the Front Control has passed. If an Actuator Calibration has not passed correct any errors before proceeding further.
9. Rotate the Rear Temperature Selector counter clockwise to the Cold Position, allow the Selector to remain in the Cold Position for 5 seconds.
10. Rotate the Rear Temperature Selector Clockwise to the Hot Position, allow the Selector to remain in the Cold Position for 5 seconds.
11. Calibration is now complete.
