Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Zone Control
The Single-Zone Air Conditioning System maintains incoming air temperature, airflow, fan speed, and fresh air intake for the entire vehicle from the instrument panel mounted A/C-Heater Control Module. The full range of temperature that the system can produce in any mode for the entire vehicle is available by positioning the blend control to the desired range.
The Dual and Three-Zone Air Conditioning systems allow completely independent side-to-side control of incoming air temperature. The full range of temperature that the front system can produce in any mode is available on either side of the vehicle by positioning the independent driver and passenger blend controls to the desired range. The three-zone system also allows the front seat occupants to completely control the Rear A/C-Heater Unit from the instrument panel mounted A/C-Heater Control Module. The intermediate and rear seat occupants can also regulate the air temperature and the fan speed of the rear unit from the rotary controls on the headliner mounted Rear Blower Rear Control.
