• Includes a blower motor resistor and wire harness pigtail
• Uses a 4-wire, 4-terminal layout with blade terminals
• Female connector with male terminals for direct electrical replacement
• 6-inch wiring harness length
• Mounts with 2 holes; mounting hardware is not included
• Package contents: 1 blower motor resistor and 1 wire harness

Detailed Description

This HVAC blower motor resistor kit is built for vehicles that use manual air conditioning controls and need replacement of a damaged resistor circuit. Dorman 973-545 addresses common failure points caused by heat damage or corrosion at the original connector, helping restore proper blower motor speed operation. It is a direct-fit electrical repair for 2003-2008 Pontiac Vibe models with manual A/C controls, and it cross-references Monroe Shocks & Struts 172286 and 182286 for the same application. The Dorman 973-545 part number is also useful when searching for an HVAC blower motor resistor kit for Pontiac Vibe manual climate control repair.

What It Helps Fix

• Blower motor works on only one speed
• Intermittent cabin fan operation
• No airflow from the HVAC vents at certain settings
• Heat-damaged resistor connector or pigtail
• Corrosion at the original electrical connection

Installation Notes and Tips

Fits 2003-2008 Pontiac Vibe, N/A, with manual air conditioning controls. Confirm the vehicle uses manual HVAC controls before ordering. Inspect the connector, terminals, and surrounding wiring for heat damage before installation. Replace any damaged wiring sections as needed so the new resistor and harness can make a secure electrical connection. The Dorman 973-545 kit uses a 1 connector, 4-wire configuration with 2 mounting holes and no gasket or seal.

Quality Assurance

Dorman supplies replacement electrical components for common OE failure points, including overheated resistor circuits and corroded connectors. This kit is built to replace the original blower motor resistor assembly on the listed Pontiac Vibe applications.
