Syatem is equipped with self diagnostic . Let me know thw results.
1. Turn ignition on. Turn blower switch OFF. Place recirculation control knob in recirculated air position (indicator light will come on). Press and hold recirculation control switch to fresh air position (indicator light goes off).
2. Continue to hold recirculation control switch until indicator light comes on for 2 seconds. At this point it will blink the Diagnostic Trouble Codes (DTCs) to indicate the faulty component. One blink indicates air mix control motor, 2 blinks indicates mode control motor, and 3 blinks indicates evaporator temperature sensor. See
Fig. 6 . If indicator lights come on, test appropriate component.
Fault information is not retained in memory. In case of multiple problems, the light will indicate the DTC with the least number of blinks.
Air mix door is for changng the air flow between A/C and heater.
