AA Ignition HVAC Blend Door Actuator — Direct-Fit Replacement for Chrysler, Dodge & Jeep 2007–2023; Replaces 604-029, Lifetime War

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

This compact motor-and-gear assembly moves your vehicle's blend and mode doors so the HVAC system can route air and mix hot and cold as intended. When the actuator fails you may hear repetitive clicking under the dash, feel air only from one vent, or be unable to change temperature — this unit replaces worn actuators with a plug-and-play fit engineered to match factory performance.

How will this actuator stop dash clicking and knocking?

A worn or stripped gear inside the blend door actuator causes the motor to slip and make audible repetitive noises while trying to move the door. Installing the AA Ignition replacement replaces the failing gear train and calibrated motor so movement is smooth and quiet again.

• Direct-fit design for straightforward swap-in without cutting or rewiring
• OE-matched gears and motor calibration reduce noise and hunting
• Replaces part number 604-029 for correct cross-reference
• Lifetime warranty through AA Ignition for added confidence
