A/C PERFORMANCE TEST

 
NOTE:
The work area ambient temperature and the evaporator temperature must be above 18.3 ?C (65 ?F) prior to conducting the A/C performance test.
 

1. Connect a manifold gauge set or an A/C recycling/charging station
2. Operate the heating-A/C system under the following conditions.
   • Engine at idle and operating temperature
   • Doors or windows open
   • Transaxle in Park or Neutral with parking brake set (depending on application)
   • A/C-heater controls set to Recirculation mode (max-A/C), full cool, panel mode, high blower and A/C on.

 

1. Insert a thermometer in the driver side center panel air outlet and operate A/C system until the thermometer temperature stabilizes.

 
NOTE:
This procedure requires the technician to know what the temperature and relative humidity is at the time of the test. The temperature must be combined with the relative humidity to calculate the apparent ambient temperature (?feels like? temperature),when the temperatures are above 21?C(70?F).Use the current ambient temperature and the relative humidity in your location. This information can be obtained from multiple sources, such as the internet or local news media.

1. Compare the air temperature at the center panel outlet and the A/C system pressures to the A/C Performance Temperature and Pressure chart.
