Global Parts 1711676 HVAC Pressure Switch

HVAC Pressure Switch for Mitsubishi A/C Control

Global Parts 1711676 is an HVAC pressure switch that sends pressure feedback to the engine management system so the A/C system can be controlled correctly. On modern vehicles, the ECM uses this signal to manage compressor operation; on earlier applications, the switch can directly shut the compressor off to help prevent failure.

Compatible With Mitsubishi Montero Sport, Mitsubishi 3000GT, Mitsubishi Diamante, and Mitsubishi Montero applications listed below, this Global Parts 1711676 pressure switch is built for binary normal-open HVAC operation.

Key Features

• Binary normal-open HVAC pressure switch design
• 3/8"-24 male thread connection
• High-pressure open at 451 psi
• High-pressure close at 375 psi
• Low-pressure open at 28 psi
• Provides pressure feedback for ECM-controlled A/C operation
• Cross-references Four Seasons 20975 for the same application

Detailed Description

This HVAC pressure switch is used in A/C pressure monitoring circuits to report system pressure and trigger compressor control logic. Global Parts Part Number 1711676 is specified as a binary normal-open switch with 3/8"-24 male fittings and defined pressure thresholds for high- and low-pressure operation. It is a direct-fit style service part for select Mitsubishi HVAC systems, including Mitsubishi Montero Sport, Mitsubishi 3000GT, Mitsubishi Diamante, and Mitsubishi Montero model years shown in the fitment list. The part number 1711676 is also referenced by several interchange numbers, making it easier to match the correct HVAC pressure switch for the application.

What It Helps Solve

• A/C compressor cycling caused by incorrect pressure signal input
• Compressor shutdown from failed high- or low-pressure switch operation
• Loss of ECM feedback for HVAC pressure monitoring
• Intermittent A/C engagement on Mitsubishi Montero Sport and Mitsubishi 3000GT applications
• Pressure-related compressor protection faults in older Mitsubishi HVAC systems

Installation Notes and Tips

• Verify the thread size and pressure specifications before installation.
• Inspect the HVAC system for refrigerant charge issues or leaks before replacing the switch.
• Confirm the connector and mounting style match the original part on the vehicle.
• Use the fitment list to match the exact Mitsubishi year and model before ordering.

Quality Assurance

Global Parts 1711676 is cataloged as an HVAC pressure switch for select Mitsubishi applications and is listed with OE-style interchange references for application matching. Confirm fitment against the vehicle year, model, and HVAC configuration before installation.
