Global Parts 1711782 HVAC Binary Switch

HVAC Binary Switch for Mitsubishi A/C Control

Global Parts 1711782 is an HVAC binary switch that provides pressure feedback to the engine management system and A/C control circuit. On modern vehicles, the ECM uses this signal to manage compressor operation; on earlier applications, the switch helps shut the compressor off before damage occurs.

Built with a rectangular male connector, this switch is a direct-fit style replacement for select Mitsubishi Diamante, 3000GT, Galant, Mirage, Montero, and Sigma applications.

Installation Notes and Tips

Verify the connector style before installation: this unit uses a rectangular male connector. Match the vehicle’s original switch location and confirm the A/C pressure switch application by year, model, and notes, especially on Mitsubishi Diamante vehicles with the before 05/1993 requirement. Inspect the electrical connector and surrounding harness for corrosion or damage before connecting the replacement part.
