Introduction
Some 2004 model year RX 330 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. An in-line thermistor
resistor harness is now available to correct this concern.
