Global Parts 3412030 A/C Expansion Valve - Rear

A/C Expansion Valve for Rear HVAC Service

Global Parts 3412030 is an A/C expansion valve for rear HVAC systems that meters refrigerant flow before it enters the evaporator. It supports cooling performance on 2018-2024 Ford Expedition and 2018-2024 Lincoln Navigator rear applications.

• Fits 2018-2024 Ford Expedition, rear
• Fits 2018-2024 Lincoln Navigator, rear
• Controls refrigerant flow ahead of the evaporator
• Supports efficient use of the refrigerant charge during A/C operation
• Global Parts part number 3412030

How This Valve Works

This expansion valve reduces refrigerant pressure and regulates flow into the evaporator so the system can absorb heat effectively. For rear HVAC service on Ford Expedition and Lincoln Navigator models, Global Parts 3412030 helps restore proper refrigerant metering when the original valve is worn, restricted, or contaminated. This part cross-references Four Seasons 39614 for the same application.

Common Problems It Can Address

• Weak rear A/C cooling
• Irregular evaporator refrigerant feed
• Restricted refrigerant flow from a worn valve
• Cooling performance loss after A/C service
• System inefficiency caused by a contaminated metering component

Installation Notes

Install Global Parts 3412030 in the rear HVAC circuit only on the listed Ford Expedition and Lincoln Navigator applications. Clean the system thoroughly before installation, replace the expansion valve/orifice tube during A/C service, and verify correct refrigerant charge and system operation after repair. Confirm vehicle year and rear HVAC configuration before ordering.

Quality Assurance

Global Parts recommends replacing the expansion valve/orifice tube each time the A/C system is serviced. That service guidance supports consistent refrigerant control and helps maintain proper evaporator performance in the rear HVAC system.
