Global Parts 1711503 A/C Compressor Cut-Out Switch

A/C Compressor Cut-Off Switch for HVAC Control

Global Parts 1711503 is an A/C compressor cut-off switch used in HVAC control systems to send feedback to the engine management system. On modern vehicles, the ECM uses this signal to manage compressor operation; on earlier systems, the switch can directly shut the compressor off to help prevent failure.

Compatible With 1998-2003 Dodge Dakota and 1998-2003 Dodge Durango applications that use a low pressure cut off switch. This part number 1711503 is built for direct replacement service in the vehicle’s air conditioning control circuit.

Key Features

• Normally open switch design
• Open 15, close 25 operating range
• Provides compressor cut-off feedback to the ECM
• Used in A/C low pressure cut-off applications
• Direct-fit service part for select Dodge HVAC systems

Detailed Description
