Theory Of Operation

WARNING: This page is about a different car, the 2013 RAM 1500. However, it is still accessible from the selected car via links, so may be relevant.

The A/C Heater Control constantly monitors the Blower Control circuit to the Blower Motor Power Module for proper operation. If the voltage or the Pulse Width Modulation (PWM) on that circuit drops below or rises above a predetermined value, a DTC will set. For further information, refer to MODULE, POWER, BLOWER MOTOR, OPERATION .
