Rear Climate Control System - GMC 2004 Envoy Owner's Manual

Rear Climate Control System

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.
