• Direct replacement HVAC blower motor resistor for select Saturn applications
• Matches original equipment operation and performance
• Blade terminal design with 4 terminals and 1 rectangular female connector
• 2 bolt-hole mounting layout for OE-style installation
• Package includes the blower motor resistor and instructions
• Part number: 973-225

Detailed Description

Dorman 973-225 is an HVAC blower motor resistor designed for vehicles that have lost one or more blower speeds due to resistor failure. By restoring the resistor circuit, it helps return normal heating and cooling control in the cabin. This part is a direct replacement for select Saturn SC, SC1, SC2, SL, SL1, SL2, SW1, and SW2 models across the 1991-2002 range, including Fits 1991-2002 Saturn SL, Fits 1991-2002 Saturn SL1, Fits 1991-2002 Saturn SL2, and Fits 1993-2002 Saturn SC1 applications.

This part cross-references Four Seasons 20420 for the same application.

What It Helps Fix

• Blower motor only working on certain fan speeds
• No cabin airflow from the HVAC system
• Intermittent heater or A/C blower operation
• Loss of low, medium, or high fan settings
• Electrical failure caused by a burnt resistor element

Installation Notes and Tips

Verify connector style, terminal count, and mounting points before installation. This resistor uses a rectangular female connector, blade terminals, and a 2-bolt mounting pattern. Mounting hardware and wiring harness are not included, so reuse the existing vehicle hardware and connector where applicable. Confirm fitment against the vehicle’s year, make, and model before service.

Quality Assurance

Dorman manufactures this replacement resistor to match OE-style function and performance for the listed Saturn applications. Part number 973-225 is intended for direct replacement use on the confirmed fitment range.
