Introduction

Some 2003 model year Corolla and Matrix 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.

Applicable Vehicles

^ 2003 model year Corolla and Matrix vehicles produced before the VINs shown below.
