Global Parts 1711234 A/C Clutch Cycle Switch

A/C Clutch Cycle Switch for GM Vans

Global Parts 1711234 is an A/C clutch cycle switch used in GM 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 systems, the switch can directly cycle the compressor off to help prevent compressor failure.

Compatible with 1996-1998 Chevrolet Express 1500, 2500, and 3500, as well as 1996-1998 GMC Savana 1500, 2500, and 3500, this accumulator-mounted switch is a direct-fit service part for the listed applications.

Key Features

• A/C clutch cycle switch for HVAC control
• Accumulator-mounted design for the listed GM applications
• Provides electrical feedback to the ECM
• Supports compressor cycling in earlier vehicle systems
• Global Parts part number 1711234

Detailed Description

This A/C clutch cycle switch is built for GM van platforms that use accumulator-mounted clutch cycling control. In the 1996-1998 Chevrolet Express and GMC Savana applications, the switch monitors system conditions and sends the signal needed for proper compressor cycling. Global Parts 1711234 is also referenced by service part number 1711234 for easy identification during HVAC repair.

This part cross-references Gates 20910 for the same application.
