AA Ignition HVAC blend door actuator is a direct-fit replacement part that restores accurate cabin temperature control and vent selection for many Chrysler, Dodge and Jeep models.

If your vehicle shows symptoms like clicking behind the dash, air coming from the wrong vents, or the temperature stuck on one setting, a failed blend or mode door actuator is often the cause. This AA Ignition unit replaces part number 604-029 and fits a wide range of Chrysler, Dodge, Jeep and Ram vehicles, offering an OE-matched gear train and a calibrated motor for quiet, reliable positioning of HVAC doors.

How does this actuator fix noisy or incorrect airflow?

The actuator replaces a worn or broken motor/gear assembly that no longer moves the blend or mode doors correctly. Once installed, it resumes precise movement so air temperature and vent selection respond to your controls instead of getting stuck or making noise.
