Global Parts 1711312 HVAC Blower Motor Relay

HVAC Blower Motor Relay for A/C Control

Global Parts 1711312 is a 12-volt, 5-pin HVAC blower motor relay with bracket mounting. It is used in vehicle A/C control circuits where the engine management system or compressor control logic needs a reliable electrical switching signal.

For Ford Escort, Cadillac Allante, and related applications, this relay supports the control path used to switch the A/C compressor off when required and to provide feedback to the ECM on modern systems.

Key Features

• 12-volt relay for HVAC and A/C control circuits
• 5-pin design with bracket
• Used as an HVAC blower motor relay / A/C compressor control relay
• Direct electrical switching for system control logic
• Global Parts part number 1711312

Detailed Description

Global Parts 1711312 is an HVAC blower motor relay built for vehicles that use relay-based A/C compressor control. The relay helps manage compressor operation through the ECM on newer systems and serves as a direct compressor shutoff switch on earlier vehicles to reduce the risk of compressor damage. This makes it a practical replacement for diagnosing or restoring HVAC electrical control on Ford Escort and Cadillac applications.

This part cross-references Four Seasons 36134 for the same application.
