HVAC Pressure Switch for Toyota Supra

Global Parts 1711488 is an HVAC pressure switch that monitors A/C system pressure and sends feedback to the engine management system. For 1987-1993 Toyota Supra applications, it supports high pressure cut-out control to help protect the compressor and maintain proper system operation.

Key Features

  • HVAC pressure switch for A/C pressure monitoring
  • Blue oval connector with male terminals
  • 2-terminal electrical connection
  • Direct-fit service part for Toyota Supra HVAC pressure switch applications
  • Global Parts 1711488 replacement for select OE-style applications

Detailed Description

This Global Parts HVAC pressure switch is built for vehicles that rely on pressure feedback to manage air conditioning operation. On modern systems, the ECM uses this signal to control A/C function; on earlier systems, the switch can shut the compressor off when pressure rises too high. That makes Global Parts 1711488 a practical replacement for a Toyota Supra HVAC pressure switch when the original unit no longer reports pressure correctly.

Fits 1987-1993 Toyota Supra, N/A. This part cross-references Four Seasons 20888 for the same application.

Common Problems This Part Can Help Solve

  • A/C compressor shutting off unexpectedly due to faulty pressure signal
  • Compressor not disengaging during high-pressure conditions
  • Intermittent air conditioning operation on Toyota Supra models
  • Incorrect feedback to the ECM or A/C control circuit
  • Failed HVAC pressure switch causing loss of compressor protection

Installation Notes and Tips

Verify the connector style before installation: this unit uses a blue oval male connector with 2 terminals. Confirm the pressure switch location and electrical connection on the vehicle before replacing the original part. For 1987-1993 Toyota Supra service, compare the old switch to Global Parts 1711488 to ensure the connector and application match.

Quality Assurance

Global Parts supplies HVAC electrical components for service replacement use. Part number 1711488 is listed with OE-style interchange references for select Toyota Supra applications.
