A/C PERFORMANCE & DURABILITY IMPROVEMENT

Some 2002 - 2003 model year Camry owners may experience a condition where the blower volume gradually decreases after about 1-1/2 hours of driving. It has been determined that, in hot high humidity conditions, the A/C system evaporator is freezing over, blocking the airflow path. There may be some instances where this condition may affect the A/C compressor and clutch assembly. An in-line thermistor resistor harness is now available to correct this concern.

APPLICABLE VEHICLES: 2002 - 2003 model year Camry vehicles produced before the VIN shown below.
