Global Parts 1711496 HVAC Pressure Switch

HVAC Pressure Switch for Mazda Applications

Global Parts 1711496 is an HVAC pressure switch that sends 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. This replacement is built with a rectangular female connector for the listed Mazda applications.

Key Features

• HVAC pressure switch for A/C system pressure feedback
• Rectangular female connector for direct electrical connection
• Supports ECM-controlled air conditioning operation on newer systems
• Used in compressor protection strategies on earlier vehicles
• Global Parts part number 1711496

Detailed Description

This HVAC pressure switch is used in the air conditioning control circuit to monitor refrigerant pressure and communicate that information to the vehicle’s control system. In Mazda 626, Mazda MX-3, and Mazda MX-6 applications, the switch helps the system respond to pressure conditions that affect compressor operation. Global Parts 1711496 is a practical replacement for diagnosing or restoring A/C pressure signal function when the original switch is no longer operating correctly.

This part cross-references Four Seasons 20953 for the same application.

What It Helps Solve

• A/C compressor not engaging because the pressure signal is not reaching the control system
• Compressor shutdown caused by an inaccurate pressure switch signal
• Intermittent air conditioning operation tied to pressure switch failure
• Faulty HVAC feedback to the ECM on pressure-controlled systems
• Loss of compressor protection logic on earlier Mazda A/C systems
