Key Features

• HVAC blower motor resistor kit with resistor and wire harness pigtail
• Direct replacement for front HVAC blower motor resistor service on select vehicles
• Female connector with male blade terminals for the specified application
• 4-wire, 4-terminal design with a 6-inch wiring harness length
• Package contents include 1 blower motor resistor, 1 wire harness, and 3 butt connectors
• Cross-reference part numbers include 4P1402 and RU1135 for the same application

Detailed Description

This Dorman blower motor resistor kit is built for 1999-2002 Mercury Villager, front, and 1999-2002 Nissan Quest, front applications. It addresses common HVAC electrical failures caused by heat damage or corrosion at the resistor connector, helping restore blower speed operation in vehicles that rely on a serviceable resistor and harness assembly. The Dorman 973-555 part number is a practical OE-style replacement when the original connector shows signs of overheating, melted terminals, or poor electrical contact.

For buyers searching for a 1999-2002 Mercury Villager blower motor resistor kit or a 1999-2002 Nissan Quest front HVAC resistor connector repair, this part number 973-555 matches the listed fitment and connector style. It is also referenced by interchange numbers such as 4P1402 and RU1135.

What It Helps Fix

• Blower motor speeds that stop working or only operate on certain settings
• Heat-damaged resistor connectors
• Corroded or loose HVAC electrical terminals
• Intermittent blower operation caused by poor contact at the resistor harness
• Front HVAC resistor circuit failures on listed Mercury Villager and Nissan Quest models

Installation Notes and Tips

Verify the original connector style, terminal count, and mounting pattern before installation. This kit uses a female connector with male blade terminals, 4 mounting holes, and no mounting hardware included. Inspect the blower motor connector and surrounding wiring for heat damage before installing the new resistor and harness. Use the included butt connectors to complete the harness repair, and confirm blower operation across all speed settings after installation.

Quality Assurance

Dorman supplies replacement electrical components for vehicle repair applications, and this kit is built to replace an overheated or corroded original equipment resistor on the listed vehicles. The Dorman 973-555 blower motor resistor kit is specified for the confirmed front fitments shown above.
