Dorman 604-260 HVAC Blend Door Actuator - Left Main, Main or Right Main

Dorman 604-260 HVAC Blend Door Actuator

Dorman 604-260 is an HVAC heater blend door actuator engineered to match the fit and function of the original unit on select Ford Mustang models. It is built with a rotary switch activation design and a plastic housing for temperature door control in vehicles with manual or dual-zone automatic climate systems.

Key Features

• Direct replacement HVAC blend door actuator for temperature control
• Rotary switch activation type for blend door movement
• Plastic construction for OE-style packaging and fit
• Used in left main, main, and right main HVAC positions on select Ford Mustang applications
• Cross-references Dayco 73079 for the same application

Detailed Description

This Dorman 604-260 blend door actuator is made for 2010-2014 Ford Mustang HVAC systems where precise air temperature control depends on accurate blend door movement. It is a practical replacement for the original actuator on Mustang models with manual temperature control, as well as dual-zone automatic temperature control applications in the left main and right main positions. The part number 604-260 is also referenced as an OE-style replacement for related applications, including Ford AR3Z19E616A.

Compatible With 2010-2014 Ford Mustang, left main temperature control with dual-zone automatic temperature control; 2010-2014 Ford Mustang, main temperature control with manual temperature control; and 2010-2014 Ford Mustang, right main temperature control with dual-zone automatic temperature control. If your Ford Mustang has inconsistent cabin temperature or a blend door that no longer responds correctly, this actuator restores the control signal needed for proper HVAC operation.

What It Helps Solve

• Cabin air stuck on hot or cold
• Temperature changes that do not match the control setting
• HVAC blend door movement that is delayed or unresponsive
• Loss of temperature control in manual or dual-zone automatic systems
• Actuator-related clicking or failed blend door positioning

Installation Notes and Tips

Verify the HVAC position and temperature control type before ordering, since this actuator is listed for left main, main, and right main applications on specific 2010-2014 Ford Mustang configurations. Confirm connector style, mounting location, and calibration requirements against the original part before installation. For best results, inspect the blend door and HVAC housing for binding or damage that could affect actuator performance.

Quality Assurance

Dorman engineers this actuator to match the quality and performance of the original blend door actuator on the listed vehicle applications. The design follows the original equipment style for fitment and function in the specified Ford Mustang HVAC systems.
