2nd Gen Ram Heater Actuator (93-02) – 04720279AB

Your heat is stuck, sluggish, or not responding to the dial. On 2nd Gen Ram trucks, the heater actuator controls the heat door in the HVAC box — and when it fails, you lose the ability to regulate cabin temperature. This is the OEM Mopar replacement, direct factory spec.

How the 2nd Gen HVAC system works:
The 2nd Gen Ram uses a mix of electric actuators and vacuum-operated doors. The heater actuator is one of the electric units — making it straightforward to diagnose. If your vacuum lines are intact and heat control is still dead, this actuator is the likely culprit.
