Global Parts 1711333 A/C Compressor Cut-Out Switch

A/C Compressor Cut-Off Switch for GM Applications

Global Parts 1711333 is an A/C compressor cut-off switch built for vehicles that rely on an electrical signal to manage compressor operation. It provides feedback to the engine management system and helps control compressor shutdown on older systems to reduce the risk of compressor damage.

Compatible With Chevrolet Tracker, GMC Tracker, Chevrolet S10, GMC Sonoma, Pontiac Trans Sport, and other listed GM applications, this switch is identified by part number 1711333 and a brown 2-terminal design.

Key Features

• Type: switch
• Brown housing with 2-terminal configuration
• Designed for A/C compressor cut-off control
• Supports ECM-based A/C system feedback on modern vehicles
• Used in earlier systems to directly interrupt compressor operation
• Global Parts part number 1711333

How It Works

This A/C compressor cut-off switch monitors system conditions and sends the needed signal to the engine management system. On newer vehicle platforms, the ECM uses that feedback to manage A/C operation. On earlier vehicles, the switch can directly turn the compressor off when conditions call for protection, helping reduce compressor failure risk. This part cross-references UAC SW10011C for the same application.

Common Problems It Can Help Address

• A/C compressor cycling issues
• Compressor shutdown caused by faulty pressure or control signaling
• Loss of feedback to the ECM in electronically managed A/C systems
• Compressor protection faults on older HVAC setups
• Intermittent A/C operation on listed Chevrolet, GMC, Pontiac, Buick, Cadillac, and Oldsmobile vehicles

Installation Notes and Tips

Verify the connector style, terminal count, and switch color before installation. Confirm the vehicle’s A/C control strategy and match the part to the exact application listed for your year, make, and model. For fitment examples, this part fits 1999-2001 Chevrolet Tracker, 1987-1995 Chevrolet S10, and 1991-1995 GMC Sonoma. It also fits 1990-1995 Pontiac Trans Sport and 1986-1990 Chevrolet Celebrity, among many other GM applications.

Quality Assurance

Global Parts 1711333 is built as an OE-style replacement switch for listed GM HVAC applications. The design follows the functional requirements of compressor cut-off control and ECM feedback used across the supported vehicles.
