RLP Heater Blend Door Actuator Passenger-Side for 2007–2014 Ford Edge & 2007–2015 Lincoln MKX — Direct-Fit with Reinforced Gears,

RLP 604-240 is a direct-fit heater blend door actuator for the passenger-side (right main) HVAC system in 2007–2014 Ford Edge and 2007–2015 Lincoln MKX vehicles.

This replacement actuator restores precise temperature and airflow control in dual-zone automatic climate systems by moving the right main blend door when the vehicle’s HVAC commands change. Built with reinforced gears and a durable plastic housing, the RLP actuator is designed to match factory fit and function while offering reliable operation and a 12-month warranty. It replaces part numbers such as 7T4Z19E616C, 604-240, 604240, and J04023.

How will this actuator affect my cabin temperature control?

When the right main blend door actuator is working correctly, the HVAC system can accurately mix warm and cool air for the passenger side in dual-zone setups. A worn or failed actuator often causes incorrect temperatures, delayed response, or audible clicking noises.

• Re-establishes proper mixing of warm and cool air for passenger side comfort.
• Eliminates erratic temperatures caused by a stuck or slipping blend door.
• Resolves common failure symptoms like clicking sounds and unresponsive vents.

Is this actuator a direct replacement and easy to install?

Yes — the RLP 604-240 is manufactured as a direct replacement to match the OEM mounting points and electrical connector for the listed Ford Edge and Lincoln MKX model years. Installation typically requires basic hand tools and removal of a small dash or glove-box panel to access the actuator assembly.

• Direct-fit unit designed to bolt in where the original actuator was installed.
• Uses the same electrical connector and gear engagement as the factory part.
• Recommended for technicians or DIYers comfortable removing interior trim panels.

What materials and construction support long-term reliability?

The actuator combines a rugged plastic enclosure with high-performance electric components and stronger gears to resist wear under repeated motion. These construction choices reduce gear stripping and motor failure that commonly occur in older actuators.

• Durable plastic housing protects internal electronics from dust and vibration.
• Reinforced gears and an upgraded motor for heavier-duty performance.
• Electrical circuitry optimized for consistent response to HVAC controls.

Which vehicles and part numbers is this compatible with?

This replacement fits the passenger-side (right main) blend door position on dual-zone automatic climate control systems for specific Ford and Lincoln models. Verify compatibility by checking your vehicle year and existing part number before purchase.

• Compatible with 2007–2014 Ford Edge (Dual Zone Automatic Temperature Control, right main).
• Compatible with 2007–2015 Lincoln MKX (Dual Zone Automatic Temperature Control, right main).
• Replaces factory part numbers: 7T4Z19E616C, 604-240, 604240, J04023.
