Global Parts 1711820 HVAC Pressure Transducer

HVAC Pressure Transducer for Cadillac Catera

Global Parts 1711820 is an HVAC pressure transducer that sends pressure feedback to the engine management system. In modern A/C systems, the ECM uses this signal to manage compressor operation; in earlier systems, it can directly shut the compressor off to help prevent failure. This part is a direct-fit style replacement for select Cadillac Catera applications.

Key Features

• HVAC pressure transducer for A/C system pressure feedback
• Supports ECM-controlled compressor operation on modern vehicles
• Used in earlier systems to help prevent compressor damage from unsafe pressure conditions
• Fits 1997-2001 Cadillac Catera, N/A
• Global Parts part number 1711820

Detailed Description

Global Parts 1711820 is built for vehicles that rely on an electrical pressure switch to communicate HVAC system pressure to the control module. For 1997-2001 Cadillac Catera models, this component helps the A/C system respond correctly to pressure changes so the compressor can be managed as intended. If you are searching for a Cadillac Catera HVAC pressure transducer or a 1711820 replacement, this part matches the listed application.

This part cross-references Monroe Shocks & Struts (e.g., SW-704) for the same application.

Common Issues It May Solve

• A/C compressor not engaging
• Compressor cycling on and off incorrectly
• Faulty pressure signal to the ECM
• HVAC system shutting down due to pressure-related faults
• Loss of compressor protection logic in the A/C circuit

Installation Notes and Tips

Verify the connector style and system diagnosis before replacement. Confirm the vehicle is a 1997-2001 Cadillac Catera and compare the original sensor location and electrical connection to the existing unit. After installation, clear any stored HVAC or engine management codes and recheck A/C operation under normal system conditions.

Quality Assurance

Global Parts supplies replacement HVAC components for service applications that require accurate pressure feedback to the control system. Part number 1711820 is listed for the specified Cadillac Catera fitment and is intended to restore proper pressure-signal operation in the A/C system.
