DESCRIPTION
| WARNING | To avoid injury from accidental air bag deployment, for 1998 vehicles, read and carefully follow all SERVICE PRECAUTIONS and DISABLING & ACTIVATING AIR BAG SYSTEM procedures in AIR BAG RESTRAINT SYSTEM article. For 1999 vehicles, see AIR BAG SAFETY PRECAUTIONS and DISABLING & ACTIVATING AIR BAG SYSTEM procedures in AIR BAG RESTRAINT SYSTEM article. |
The A/C-heater system automatically adjusts passenger compartment temperature via control unit, integrated into A/C-heater control panel. (Scheme 20) The A/C-heater control unit regulates heater operation through an electromagnetic water valve. The electromagnetic water valve controls flow rate through heater core.
Air temperature is regulated by mixing varying ratios of cold and heated air through temperature mixing flap. (Scheme 21) Temperature and air distribution for driver's side and front passenger's side can be controlled separately. All outlets can supply heated, cooled, or fresh air according to temperature setting. Outside air is drawn through a microfilter to filter pollen and dust. (Scheme 20)
System uses 5 input sensors: interior temperature sensor, exterior temperature sensor, left heater core temperature sensor, right heater core temperature sensor, and evaporator temperature sensor. Temperature sensors continuously input information to A/C-heater control unit. The A/C-heater control unit processes sensor signals and adjusts system temperature accordingly.
Some models are available with a rear A/C-heater control panel. Rear A/C-heater control panel is located on the back of the center console. (Scheme 22) These controls can be used to regulate air temperature and rear blower motor speed to rear of passenger compartment by rear passengers.
Vehicle is also equipped with a Residual Heat Utilization (REST) function. (Scheme 20) This function allows the interior of the car to be heated when engine is turned off. The system will automatically direct heated air to windshield, side windows, and footwell.
