2003 Dodge Ram Van 3500 Problems

HVAC Air Flow Switching to Defrost When Accelerating

The AC/heater (HVAC) system may unexpectedly switch to the defrost mode when accelerating. This system is operated by engine vacuum and should be inspected for any vacuum leaks if this problem develops.  There is also a revised vacuum check valve available to address this concern.

Intermittent cycling of power door locks
Intermittent cycling of the door locks especially during damp conditions may occur. Our technicians tell us that revised door and liftgate lock cylinder switches are available.
High Blower Only Due to Failed Blower Motor Resistor

The HVAC blower may operate on high speed only. This is commonly caused by a failed blower motor resistor. Chrysler has released a revised part to address this problem.
