Fits 2005-2009 Chevrolet Uplander, front; fits 2005-2009 Pontiac Montana, front; and fits 2005-2007 Buick Terraza, front.

Key Features

• HVAC blower motor resistor for front-position applications
• Supports blower speed control in manual air conditioning systems
• Direct replacement part number 1711728 for select GM vehicles
• Cross-references Dorman - OE Solutions 973-536 for the same application
• Also cross-references UAC SW11290C

Detailed Description

This Global Parts blower motor resistor is used in HVAC systems where the blower motor needs stepped speed control through the resistor circuit. On modern vehicles, the A/C system is managed through the engine control system; on earlier designs, related electrical switching functions were used to help protect the compressor from failure. This part number 1711728 serves select Buick, Chevrolet, Pontiac, Saturn, and Oldsmobile applications listed in the fitment data, including Buick Rendezvous with manual A/C and the specified pigtail note.

Additional vehicle coverage includes 2005-2007 Saturn Relay, 2004-2005 Pontiac Aztek, 2003-2004 Oldsmobile Silhouette, and 2001-2002 Pontiac Montana. Verify the HVAC configuration and connector requirements before ordering, especially where the fitment notes specify manual A/C or pigtail use.

What It Helps Fix

• Blower motor stuck on one speed
• Intermittent cabin fan operation
• No low, medium, or high fan settings
• HVAC airflow that changes unpredictably
• Resistor-related fan control faults in manual A/C systems

Installation Notes and Tips

Install in the front HVAC location shown in the fitment data and confirm the connector style matches the vehicle harness. For 2002-2007 Buick Rendezvous, the notes specify manual A/C and pigtail use 1711755. Inspect the blower motor connector, wiring, and surrounding HVAC components for heat damage before installation.
