Dorman HVAC Blend Door Actuator 604-024 — Direct-fit replacement that restores cabin temperature control

If your vehicle’s cabin temperature is inconsistent, vents are stuck on one setting, or the heater/AC blend doors don’t respond, worn or failed actuators are a common cause. The Dorman 604-024 is engineered to match the original actuator’s fit and function for specified model years and configurations, so you can replace a faulty unit without modifying the HVAC system. Always confirm fitment for your specific trim and actuator position before ordering.

Which vehicles and years is this actuator compatible with?

This actuator is designed for select model years of Chrysler, Dodge, Ram and Volkswagen vehicles. Compatibility covers many Chrysler 300, Dodge Challenger and Charger years plus minivans and trucks—but not every trim or HVAC position. Use the vehicle lookup tool or the part’s application notes to confirm match for your exact make, model, year and actuator location.

• Fits Chrysler 300 (2008–2023), Town & Country (2008–2016)
• Fits Dodge Challenger and Charger (many years 2008–2023) and Grand Caravan (2008–2020)
• Also fits Dodge Dakota, Ram C/V, Ram Dakota, Mitsubishi Raider and VW Routan specific years

How does this replacement actuator restore HVAC performance?

The Dorman 604-024 replaces a failing actuator that moves the HVAC blend door to regulate cabin temperature. By restoring accurate positioning and electrical connection, it helps the system mix hot and cold air as intended and respond correctly to climate-control commands.

• Matches original mounting points and electrical connector for straightforward installation
• Restores motorized movement of the blend door to correct temperature inconsistencies
• Compatible with vehicle control signals to eliminate erratic HVAC behavior

What should I check before buying and installing this part?

Many vehicles have multiple actuator units that control different doors (blend, mode, recirculation). Verify you need the 604-024 for the correct position. If unsure, consult the application notes, enter vehicle trim in the fitment tool, or seek a professional diagnosis to avoid ordering the wrong actuator.

• Use the online garage tool and check the Confirmed Fit indicator at the top of the page
• If a blue “i” appears, hover or review fitment notes for additional verification steps
• Confirm actuator position (blend door vs. mode door) before purchase

What are the product’s build quality and reliability features?

Dorman designs and tests replacement actuators to meet strict durability and electrical standards so they withstand normal HVAC loads and resist premature electrical failure. The unit is manufactured under established quality processes and supported by Dorman’s engineering team in the United States.

• Durable construction to resist wear and reduce risk of electrical burnout
• Engineered to mirror OEM fit and function for reliable service life
• Backed by Dorman’s technical support and decades of parts experience

Who this is for: The Dorman 604-024 actuator is suited to vehicle owners and independent shops replacing a failed blend door actuator on supported Chrysler, Dodge, Ram, Mitsubishi or Volkswagen models. It’s ideal for anyone who needs a direct-fit, serviceable replacement without modifying the HVAC system — provided they confirm the actuator’s position and fitment for their exact year and trim.
