Dorman 973-557 HVAC Blower Motor Resistor Kit

Dorman 973-557 HVAC Blower Motor Resistor Kit

Dorman 973-557 is an HVAC blower motor resistor kit that replaces a failed original resistor and includes the matching harness pigtail for a cleaner electrical repair. It is built for select Mercury Villager and Nissan Quest applications where the blower speed circuit has been damaged by heat or corrosion.

Key Features

• Includes a blower motor resistor and wire harness for the repair
• Female connector with male blade terminals for the specified application
• 4-wire harness with a 6-inch lead length
• 3 mounting holes for direct-fit installation on the supported vehicles
• Designed for HVAC blower speed control circuit repair
• Cross-references Dorman 973-557 for the same application

Detailed Description

This HVAC blower motor resistor kit is a direct replacement solution for select 1993-1998 Mercury Villager and 1993-1998 Nissan Quest models. Dorman 973-557 addresses the resistor and connector side of the repair by pairing the resistor with a replacement harness pigtail, which is important when the original connector has been overheated, brittle, or corroded. The blade-style terminals, 4-terminal layout, and 3-hole mounting pattern support a proper electrical and physical match for the listed vehicles.

For buyers searching for a 1993-1998 Mercury Villager blower motor resistor kit or a 1993-1998 Nissan Quest HVAC resistor replacement, this part provides the needed components for restoring blower speed operation. Dorman 973-557 is also a practical choice when the original resistor has failed from heat damage and the connector shows signs of terminal wear.

What It Helps Fix

• Blower motor works on only one speed
• Loss of one or more HVAC fan speeds
• Intermittent cabin airflow from the vents
• Heat-damaged or corroded resistor connector
• Electrical resistance issues in the blower control circuit

Installation Notes

Verify connector style, terminal count, and mounting-hole layout before installation. Inspect the blower motor connector and surrounding wiring for heat damage, then replace any damaged terminals or pigtail sections as needed. Confirm fitment for your exact year and model before ordering, especially on Mercury Villager and Nissan Quest HVAC repairs.

Quality Assurance

Dorman supplies replacement electrical components engineered to match the original application requirements for the listed vehicles. This part is intended for direct replacement use on the confirmed fitment shown above.
