Theory Of Operation

WARNING: This page is about a different car, the 2012 RAM Pickup. 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 Module for proper operation. If the voltage on that circuit drops below or rises above a predetermined value, a DTC will set.
