Air Conditioning Indicator Lamp: Service and Repair

This lamp will be illuminated when the A/C system detects a low refrigerant charge. The lamp will be illuminated for approximately 2 seconds after ignition switch has been placed in the On position as a bulb check. If while operating vehicle, the lamp illuminates for approximately 60 seconds and then goes off, the refrigerant level is low enough to cause reduced cooling capacity. At this point the blower motor will increase speed to try to offset the loss in cooling capacity. The lamp will be automatically reset after system has been checked and refrigerant charge has been brought to proper level.

If lamp is illuminated for approximately 60 seconds after engine start
up, the refrigerant charge may be low enough to cause A/C compressor damage. When this condition is encountered, the A/C compressor clutch is de-energized and the A/C system is switched from Auto to Econ. The system will remain in Econ until necessary repairs are made and system is recharged. After completing necessary repairs and recharging the system, A/C system operation will return to normal and the lamp will be automatically reset.
