Rear Climate Control System - GMC 2003 Envoy XL Owner's Manual

Rear Climate Control System
Your vehicle has one of the following rear comfort
control systems. With either system, the rear comfort
controls will be disabled when the front comfort 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 comfort controls on and off. Use the mode knob
to change the direction of airflow (upper, bi-level or floor)
to the rear seat area.
