How This Switch Works

This A/C clutch cycle switch monitors refrigerant pressure and sends feedback to the ECM or directly interrupts compressor operation on earlier systems. On select Buick, Chevrolet, Cadillac, and GMC vehicles, that control helps prevent compressor damage by cycling the compressor at the proper pressure range. Global Parts 1711371 is a fitment-specific replacement for GM HVAC systems that use a 2-spade cycling switch design.

This part cross-references Four Seasons 36496 for the same application.

Common Problems It Can Help Solve

• A/C compressor cycling on and off too frequently
• Compressor not engaging when the system is charged
• Intermittent cabin cooling on GM trucks and vans
• Pressure-switch related A/C shutdowns
• Faulty ECM feedback from the HVAC pressure circuit

Installation Notes

Verify the connector style, mounting location, and vehicle application before installation. This switch is listed for blade-connector and accumulator-mounted configurations on the vehicles shown above. Compare the original part number and connector layout to confirm a proper match for your Buick Roadmaster, Chevrolet Caprice, or GMC Savana application.

Quality Assurance

Global Parts 1711371 is built as an electrical HVAC switch for direct-fit replacement use on the listed GM applications. The manufacturer describes this component as a pressure-cycle switch used for ECM feedback and compressor protection in A/C systems.
