Global Parts 1711742 HVAC Pressure Switch

HVAC Pressure Switch for GM A/C Control

Global Parts 1711742 is an HVAC pressure switch used in vehicle air conditioning systems to provide pressure feedback to the engine management system. On modern vehicles, the ECM uses this signal to manage A/C operation; on earlier systems, the switch can directly shut the compressor off to help prevent compressor damage.
