Product Details and Specifications

The Dorman 973-256 blower motor resistor is built with a rectangular female connector housing four terminals—two male blade and two aspa types—ensuring compatibility with the Nissan Quest's HVAC wiring system. It mounts securely using three bolt holes, providing a stable connection to the blower motor assembly. This resistor does not include a wiring harness or mounting hardware, so ensure your existing components are intact before installation. The package includes the resistor and detailed instructions to assist with replacement.

Compatible Vehicles and Applications

This blower motor resistor is specifically designed for use in Nissan Quest vehicles. It regulates the blower motor speed by controlling electrical current, which is essential for maintaining proper airflow through the HVAC system. Common issues addressed by replacing this resistor include:

• Blower motor only working on certain speeds
• Intermittent or no airflow from vents
• HVAC blower motor stuck on high speed
• Inconsistent heating or cooling performance
• Electrical resistance failure causing blower motor malfunction

Installation Notes and Tips

Before installation, verify that the part number 973-256 matches your vehicle’s requirements. Disconnect the battery to prevent electrical shorts. Remove the old blower motor resistor by unscrewing the three mounting bolts and disconnecting the rectangular female connector. Install the new resistor by securing it with the three bolts and reconnecting the connector firmly. Since no wiring harness or mounting hardware is included, reuse existing components if they are in good condition. Test the blower motor operation across all speed settings after installation.
