Global Parts 1711675 HVAC Pressure Switch

HVAC Pressure Switch for Mitsubishi A/C Control

Global Parts 1711675 is an HVAC pressure switch that sends pressure feedback to the engine management system so the A/C system can be controlled correctly. On earlier vehicles, this type of switch can also shut the compressor off to help prevent compressor damage when pressure conditions are out of range.

• Female connector gender for direct electrical connection
• HVAC binary operation pressure switch design
• Supports A/C pressure feedback to the ECM on modern systems
• Used to interrupt compressor operation on earlier applications
• Cross-references Mitsubishi OE numbers MR278181 and MR360872

Compatible With: Fits 2003-2006 Mitsubishi Lancer, N/A; Fits 1999-2003 Mitsubishi Galant, N/A; Fits 1993-2000 Mitsubishi Montero, N/A; Fits 1997-2000 Mitsubishi Montero Sport, N/A.

What It Helps Fix

• A/C compressor not engaging due to pressure switch failure
• Intermittent compressor shutdown from incorrect pressure feedback
• Faulty HVAC pressure signal to the ECM
• Loss of compressor protection logic on older Mitsubishi systems
• Air conditioning performance issues tied to switch malfunction

Installation Notes and Tips

Verify the connector style before installation; this part uses a female connector. Confirm the original switch part number and vehicle application against the listed fitment for Mitsubishi Lancer, Galant, Montero, and Montero Sport models. Inspect the A/C system for underlying pressure or refrigerant issues before replacing the switch, since abnormal system pressure can trigger repeat failures.
