Chrysler Repair: `04 pacifica a/c controls, automatic temperature control, ambient air temperature

Question
How can I calibrate and test the new a/c heater control unit on 04 pacifica? (simultaneously getting cold air from the a/c)and what is the problem of not getting any cold air (just warm) from the drivers side but getting cold from passengers side? yesterday very tiny amount of smoke came out from the engine compartment and there was a sound coming from the drivers side compartment after that . Then when I turned the a/c on again the same sound came second time and ducts on drivers side started not giving cold air.

Answer
DIAGNOSIS AND TESTING - A/C COOL DOWN TEST
The A/C-heater control module can perform an A/C cool down test, which is a test performed during the manufacturing process to confirm that the air conditioning system is performing satisfactorily. This test can also provide a quick confirmation of air conditioning system performance to the service technician. If the test is completed satisfactorily, no further service is required. If the test is failed, proceed to the A/C Performance Test to confirm the A/C system is operating properly, or use a DRBIII® scan tool to diagnose the A/C system control and distribution systems. Refer to the appropriate diagnostic information.

AUTOMATIC TEMPERATURE CONTROL
The ambient air temperature in the room where the vehicle will be tested must be a minimum of 21° C (70°F) for this test. The test is activated by depressing the A/C and PWR buttons simultaneously and holding them depressed for no less than four seconds. The snowflake icon and the DELAY text in the A/C-heater control display will blink on and off alternately until the test is complete. If the snowflake icon and the DELAY text stop blinking before two minutes, then the cool down test has been completed successfully. If the two minutes expire without the evaporator temperature reaching 11° C (20° F) less than the evaporator initial temperature, then the cool down test has been failed and further A/C system diagnosis is required. If the test is failed, the snowflake icon and the DELAY text will continue to blink across ignition cycles until the vehicle has been driven for greater than 12 km (8 miles).
