How It Works

This actuator receives commands from the HVAC control system and positions the blend door to regulate cabin air temperature. In systems using the same HVAC architecture, related doors manage vent direction and recirculation, helping the climate controls respond correctly. Global Parts 1712366 is listed for Buick Rendezvous models from 2002 through 2007, including vehicles with RPO CJ3 and C60.

Common Problems It Can Address

• Incorrect cabin temperature output
• Temperature stuck on hot or cold
• Clicking or ticking from behind the dash
• HVAC controls that do not respond as expected
• Airflow that does not match the selected climate setting

Installation Notes

Verify the vehicle’s RPO codes and HVAC configuration before ordering. On Buick Rendezvous applications, access is typically behind the dash near the HVAC case, so confirm the actuator location and connector style against the original unit. After installation, cycle the ignition and test temperature changes through the full range to confirm proper operation.

Quality Assurance

Global Parts 1712366 is built as an OE-style replacement for the listed Buick Rendezvous applications. It cross-references Standard Ignition ADR135 and Dorman OE Solutions 604-900 for the same application.
