Global Parts 1711844 HVAC Pressure Switch

HVAC Pressure Switch for Jaguar A/C Control

Global Parts 1711844 is an HVAC binary normal-close pressure switch used in Jaguar air conditioning systems to provide pressure feedback to the engine management system. On modern vehicles, the ECM uses this signal to manage A/C operation; on earlier systems, the switch can directly shut the compressor off to help prevent compressor damage.

• Binary normal-close HVAC pressure switch
• 7/16"-20 female fittings on both ports
• High-pressure open at 375 psi
• High-pressure close at 451 psi
• Low-pressure open at 28 psi
• Direct-fit pressure switch for Jaguar HVAC service

Fitment and Application Details

Compatible with 1995-1997 Jaguar Vanden Plas, N/A; 1996-1997 Jaguar XJ6, N/A; 1995-1997 Jaguar XJR, N/A; and 1995-1996 Jaguar XJS, N/A. This part number 1711844 is a direct reference for Jaguar HVAC pressure switch service on these applications. This part cross-references LNA7655BA and SW11106 for the same application.

As an HVAC pressure switch, this component monitors refrigerant pressure and sends the proper signal to the control system so the A/C compressor can be managed correctly. For Jaguar Vanden Plas, XJ6, XJR, and XJS models, the switch supports pressure-based compressor control and helps maintain system protection during normal operation.

Common Problems This Part Can Address

• A/C compressor not cycling correctly
• Compressor shutdown caused by incorrect pressure signal
• Loss of HVAC pressure feedback to the ECM
• System protection faults related to refrigerant pressure
• Intermittent air conditioning operation on Jaguar HVAC systems

Installation Notes and Tips

Verify the connector style and thread size before installation. Confirm refrigerant pressure is within specification and inspect the surrounding HVAC components for leaks or contamination before replacing the switch. After installation, clear any stored HVAC or engine management fault codes and confirm compressor operation under normal system pressure.

Quality Assurance

Global Parts 1711844 is built as an HVAC pressure switch for vehicle-specific service applications and follows the operating thresholds listed above for pressure-based A/C control.
