Global Parts 1711790 HVAC Pressure Switch

HVAC Pressure Switch Overview

This Global Parts HVAC pressure switch, part number 1711790, provides pressure feedback to the engine management system and helps control A/C compressor operation. It is a direct-fit service part for a specific Volvo application and is built for pressure-cycle switching in the air conditioning circuit.

Key Features

• HVAC pressure switch for A/C system pressure monitoring
• Cycle-switch type for compressor control logic
• Designed to communicate pressure status to the ECM
• Fits 1992 Volvo 960, N/A, with 7/16-20 thread
• Global Parts part number 1711790 for catalog matching

Detailed Description

The Global Parts 1711790 HVAC pressure switch is used in air conditioning control circuits where pressure feedback is required for compressor management. On modern systems, the ECM uses this signal to regulate A/C operation; on earlier systems, the switch can interrupt compressor operation to help prevent damage from unsafe pressure conditions. This part is listed for the 1992 Volvo 960, N/A, with a 7/16-20 thread, making fitment verification straightforward before service. If you are replacing a failed Volvo 960 HVAC pressure switch, 1711790 is the reference number to match.

What It Is Used For

• Restoring A/C pressure signal feedback to the control system
• Addressing compressor shutdown caused by a faulty pressure switch
• Correcting intermittent A/C cycling behavior
• Replacing a switch with damaged threads or electrical failure

Installation Notes and Tips

Verify the thread specification and connector style against the original switch before installation. Confirm the vehicle application as 1992 Volvo 960, N/A, and compare the removed part to part number 1711790 to ensure the correct HVAC pressure switch is selected. Check the A/C system for proper refrigerant charge and related faults before replacing the switch.

Quality Assurance

Global Parts supplies service replacement components for HVAC control applications, and this pressure switch is cataloged for a defined vehicle fitment and thread specification.
