Dorman 973-220 HVAC Blower Motor Resistor

Dorman 973-220 Blower Motor Resistor

Restore HVAC fan control with this direct replacement blower motor resistor from Dorman. It is built to match the operation and performance of the original equipment on select vehicles, including the 2000-2006 Nissan Sentra.

• Direct replacement for the original blower motor resistor
• Blade terminal type for OE-style electrical connection
• Package contents include the blower motor resistor and instructions
• Designed for heating and cooling fan speed control restoration
• Dorman part number 973-220 for easy identification

OE-Style HVAC Fan Speed Control

The Dorman 973-220 is an HVAC blower motor resistor used to restore proper blower motor speed operation when the original resistor has failed. In vehicles such as the Nissan Sentra, a worn or burnt resistor can prevent the cabin fan from working at all speeds or can leave only certain speeds available. This replacement is made to follow the function of the factory part so the heating and cooling system can return to normal operation. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Blower motor only working on one speed
• Fan speeds that stop responding
• No cabin airflow from the HVAC system
• Intermittent heating or cooling fan operation
• Burnt or failed blower motor resistor diagnosis

Installation Notes

Fits 2000-2006 Nissan Sentra, N/A. Verify the blade terminal layout and connector condition before installation. Mounting hardware is not included. Follow the included instructions and inspect the blower motor connector and wiring for heat damage, since a failed resistor can sometimes leave related terminals discolored or weakened.

Quality Assurance

Dorman designs this replacement resistor to match original equipment operation and performance on the listed applications. Part number 973-220 is intended for direct-fit service on the confirmed Nissan Sentra fitment shown above.
