Global Parts 3411942 A/C Expansion Valve - Rear

Rear A/C Expansion Valve for Nissan and INFINITI

Global Parts 3411942 is a rear A/C expansion valve for select Nissan Armada and INFINITI full-size SUVs. It meters refrigerant flow before the evaporator so the system can use the refrigerant’s cooling capacity efficiently.

• Rear A/C expansion valve for HVAC refrigerant flow control
• Fits 2017-2024 Nissan Armada, rear
• Fits 2014-2019 INFINITI QX80, rear

How It Works

This A/C expansion valve reduces refrigerant pressure and regulates refrigerant delivery into the evaporator. In rear HVAC systems on the Nissan Armada, INFINITI QX80, and INFINITI QX56, that control helps the evaporator absorb heat correctly and maintain stable cooling performance. This part cross-references Four Seasons 39585 for the same application.

Common Repair Symptoms

• Weak rear A/C cooling
• Uneven evaporator performance
• Restricted refrigerant flow at the rear HVAC circuit
• System service issues after component replacement
• Need for a direct replacement during A/C service

Installation Notes

Install during rear A/C service on the affected vehicle application and verify the system is properly evacuated, recharged, and leak-checked after replacement. Global Parts recommends replacing the expansion valve/orifice tube each time the A/C system is serviced. Confirm rear-position fitment before ordering; this part number 3411942 is listed for rear applications only.
