A-NAFTULY HVAC Blend Door Actuator Replacement Pair for Chevy Impala 2004–2013 — Direct-Fit, ABS Housing

A-NAFTULY 2Pcs HVAC Blend Door Actuator is a direct-fit replacement motor that restores precise vent temperature control for select Chevy, Buick and Pontiac models.

If your vehicle’s vents blow only hot or cold air, make grinding noises when changing temperature, or the climate zones don’t respond correctly, a failing blend door actuator is often the cause. This A-NAFTULY two-piece replacement set matches OEM mounting points and electrical connections for a reliable repair that’s suitable for DIYers and professional installers alike. Built from durable ABS housings and modern internal circuitry, the actuators are designed to deliver consistent movement and long service life across the listed GM vehicles.

How will this actuator fix inconsistent cabin temperatures?

Replacing a worn or burnt actuator restores the mechanism that moves the HVAC blend door, allowing the system to mix hot and cold air properly. Once installed and recalibrated, the actuator enables the HVAC module to reach the set temperature accurately and respond to zone controls.

• Direct replacement for OEM part numbers 604108, 1573517, 1574122 and others
• Restores smooth actuator movement and eliminates clicking or grinding noises
• Helps the HVAC control unit achieve accurate left/right temperature balance

Will these actuators fit my Chevy, Buick or Pontiac?

The pair is compatible with a range of GM models and years commonly affected by blend door failures. Confirm fitment using your vehicle year/make/model before ordering to ensure correct match with factory mounting and connectors.

• Fits Chevy Impala 2004–2013 and Limited 2014–2016, Corvette 2005–2013, Malibu 2004–2008, Monte Carlo 2004–2007
