Your Envoy has one of the following rear climate control systems. With any of these systems, the rear climate controls will be disabled when the front climate control system is in defrost. This occurs to provide maximum airflow to clear the windshield.

The temperature of the air coming through the rear outlets is determined by the front passenger's temperature setting. Press the PWR button to turn the rear climate controls on and off. Use the mode knob to change the direction of airflow (upper, bi-level or floor) to the rear seat area.

If your vehicle has the rear seat audio system, the lower buttons are used to adjust the rear seat climate controls. The temperature of the air coming through the rear outlets is determined by the front passenger's temperature setting.

If the front climate control is on and not in defrost mode, the rear climate control can be enabled by pressing the lower power button (center button) on the control face. If the front is off or is in defrost mode, the rear climate control will flash "OFF" if the power button is pressed, indicating the function is unavailable at this point.

The fan speed is controlled by the fan speed toggle button. The mode button, on the right, controls where the air is vented.

To operate the rear air conditioning system, the front air conditioning system must be on. With the front air conditioning system off, the rear system controls can only be used to circulate air in the rear of the vehicle.

(Floor): When floor mode is selected in the front controller, the rear system will distribute air from the third seat floor outlet.

(Defog): When defog mode is selected in the front controller, the rear system will distribute air from the third seat floor outlet.

Outlet Adjustment

Your vehicle may have rear seat outlets that can be used to adjust the airflow toward either seating area, the floor or upward. Move the control in the center of each outlet in any direction to direct airflow.
