Detailed Description

The Mopar 68396059AB HVAC mode door actuator is used to control where conditioned air is directed inside the cabin. In affected Ram 1500, Ram 2500, Ram 3500, Ram 4500, and Ram 5500 models, a failing actuator can leave the system stuck on one vent setting, create inconsistent airflow, or prevent the HVAC controls from changing modes correctly. This replacement actuator is specified for Main position fitment and supports proper operation of the air distribution system. If you are replacing a worn HVAC mode door actuator on a Ram 1500 or other listed Ram heavy-duty truck, 68396059AB provides the correct service part reference.

What It Is Used For

• Fixes HVAC airflow that stays locked on one outlet
• Addresses clicking or repeated movement from a worn actuator
• Restores response when mode changes do not match the control setting
• Helps correct uneven or incorrect cabin air distribution

Installation Notes and Tips

Verify the part number and Main position fitment before ordering. Access to the actuator is typically through the HVAC housing, so confirm the vehicle’s service procedure and calibration requirements for the specific Ram application. After installation, cycle the HVAC controls to confirm smooth mode door operation.

Quality Assurance

This is a Mopar service part identified by OEM part number 68396059AB, intended for the listed Ram applications.
