HVAC Blower Motor Resistor Kit for Nissan and INFINITI

Dorman 973-581 is an HVAC blower motor resistor kit that replaces an overheated or corroded original resistor on select Nissan and INFINITI vehicles. It includes the resistor and a replacement harness pigtail to restore blower motor speed control in manual climate control systems.

Key Features

• Direct replacement HVAC blower motor resistor kit for select Nissan and INFINITI applications
• Includes a replacement wire harness pigtail for damaged or heat-affected factory connectors
• Blade terminal design with a male connector and male terminals
• 4-wire harness with 3 terminals and a 30 cm wiring harness length
• 2 mounting holes for OE-style installation points
• Package contents: blower motor resistor and wire harness
• Cross-references Dorman 973-581 for applications that use OE-style resistor kit replacements

Detailed Description

This Dorman HVAC blower motor resistor kit is built for vehicles that use manual climate control and need a replacement for a failed resistor or connector damage at the blower circuit. It is a practical repair for Nissan Rogue, Nissan Pathfinder, Nissan Sentra, INFINITI QX60, and other listed applications where blower speeds stop working correctly because the original resistor has overheated or the connector has corroded. Dorman 973-581 is intended to restore proper blower motor operation by replacing the electrical components at the source of the fault.

Compatible With 2017-2023 Nissan Qashqai, w/Manual Climate Control; 2018-2022 Nissan Rogue Sport, w/Manual Climate Control; 2018-2020 Nissan Rogue, w/Manual Climate Control; 2014-2017 INFINITI QX60; 2012-2017 Nissan NV3500; 2013-2017 Nissan Pathfinder; 2008-2017 Nissan Rogue; 2017 Nissan Rogue Sport; 2017 Nissan TITAN; 2017 Nissan TITAN XD; 2014-2015 Nissan Rogue Select; 2012-2014 Nissan NV1500; 2012-2014 Nissan NV2500; 2007-2012 Nissan Sentra; 1996-2004 Nissan Pathfinder, Automatic Air Conditioning (w/AC); 1997-2003 INFINITI QX4, Automatic Air Conditioning (w/AC); 1999-2002 INFINITI G20, Automatic Air Conditioning (w/AC); 1997-2001 INFINITI Q45, Automatic Air Conditioning (w/AC); 1998-1999 INFINITI I30, Automatic Air Conditioning (w/AC); 1997-1999 Nissan Maxima, Automatic Air Conditioning (w/AC).

What It Helps Fix

• Blower motor speeds that no longer work on one or more settings
• Intermittent HVAC fan operation caused by heat-damaged resistor circuits
• Corroded, melted, or loose blower resistor connector terminals
• Loss of cabin airflow from a failed resistor assembly
• Electrical resistance issues in the blower motor control circuit

Installation Notes and Tips

Verify the vehicle uses the listed climate control configuration before ordering, especially on Nissan Rogue, Nissan Pathfinder, and INFINITI QX60 applications. Inspect the blower connector and surrounding wiring for heat damage before installation, and replace any damaged terminals or harness sections as needed. The kit uses a 4-wire harness and blade terminals, so confirm connector style and mounting hole alignment against the original part before service.

Quality Assurance

Dorman designs replacement electrical components to address common OE failure points such as overheating and connector corrosion. This kit is built as a service replacement for the original blower motor resistor assembly on the listed vehicles.
