AIR CONDITIONING DESCRIPTION AND OPERATION 82-19 In the defrost mode, the inlet air source is set to fresh air except at low ambient air and coolant temperatures. If, within − 16 ° C (3 ° F) or less and the heater coolant temperature is − 10 ° C (14 ° F) or less, then the inlet air source is automatically set to the timed recirculated air mode. The timed recirculated air mode is cancelled Timed recirculated air ± 1 minutes, after which it automatically reverts to fresh air. Timed recirculated air can be manually selected: l In the automatic mode, by pressing the fresh/recirculated air switch for 1.5 seconds or more; the audible warning l In the economy or defrost modes, by pressing the fresh/recirculated air switch for less than 1.5 seconds; the Latched recirculated air l In the automatic mode, by pressing the fresh/recirculated air switch for less than 1.5 seconds; the audible l In the economy or defrost modes, by pressing the fresh/recirculated air switch for 1.5 seconds or more; the Blower control In the automatic, economy and defrost modes, blower speed is corrected for vehicle speed to compensate for the In the automatic and economy modes, if the LH or RH temperature is set to LO or HI, the blower runs at maximum l During warm-up, the blower speed is set to 3 while the heater coolant temperature is below approximately 20 ° C (68 ° F). From approximately 20 ° C (68 ° F), the blower speed is progressively increased as the coolant temperature increases, until maximum speed is set at approximately 50 ° C (122 ° F). l During cool down, blower speed is set to 3, for 5 seconds after the system is switched on. Over the following 6 l As the temperature in the cabin approaches the selected temperatures, blower speed is progressively reduced l Solar heating correction is employed when air distribution is set to face level or to face and footwells.
