B1604 JEEP Description

The Heating Ventilation and Air Conditioning (HVAC) A/C Heater Module uses a variety of sensors to adjust HVAC operation to obtain optimal performance. These sensors are continuously monitored by the A/C Heater Module to assure that they are in range. The A/C Heater Control monitors the Right Solar Sensor. If the Right Sunload Sensor input is out of range toward the low voltage threshold, the A/C Heater Control will set the OBDII code.
