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