Description

GENERAL DESCRIPTION
The Heating, Ventilation and Air Conditioning (HVAC) system is designed to provide a comfortable environment inside the vehicle passenger compartment, regardless of weather conditions outside the vehicle. The HVAC system is most easily understood if you break it up into its major functional systems:

1. Air Distribution System.
2. Temperature Control system.
3. Refrigeration System.
4. Heater System.

NOTICE: The refrigeration system on this vehicle uses Refrigerant-134a (R-134a) which is not compatible with refrigerant R-12. Before servicing the system always make sure the proper servicing equipment is used or the system could become severely damaged. Always refer to the service text and manufacturers instructions included with service equipment before proceeding.
