Global Parts 1711426 A/C Clutch Cycle Switch

A/C Clutch Cycle Switch for GM HVAC Control

Global Parts 1711426 is an A/C clutch cycle switch used in HVAC systems to provide feedback to the engine management system. On modern vehicles, the ECM uses this signal to manage A/C operation; on earlier applications, the switch can directly cycle the compressor off to help prevent compressor damage.
