Four Seasons 70057 HVAC Blower Motor Resistor Harness - Front or Rear

Four Seasons 70057 Harness Connector

The Four Seasons 70057 harness connector is a direct-fit HVAC electrical connector for blower motor resistor circuits that use a 6-terminal male interface. Built with a square connector shape, blade terminals, and 10 & 12 gauge wire, it supports clean replacement of damaged or heat-affected blower resistor wiring on a wide range of Chrysler, Dodge, Jeep, Ford, GM, BMW, and Lincoln applications.

Four Seasons Harness Connector line parts are built for HVAC wiring repairs where the original connector has melted, loosened, or lost terminal integrity. This connector uses a 6.000-inch lead length and female terminals to restore a secure electrical connection at the blower motor resistor harness.

• Part number 70057 for HVAC blower motor resistor harness repair
• Square connector shape with blade-style terminals
• 6-terminal design with female terminal gender
• 10 & 12 gauge wire sizing for common HVAC harness repair needs
• 6.000-inch wire length for connector-side replacement work
• Cross-references Four Seasons 70057 for the same application

Detailed Product Overview

This HVAC blower motor resistor harness connector is used in vehicles where the factory connector at the resistor or related HVAC circuit has been damaged by heat, corrosion, or terminal wear. It is listed across many fitments including Chrysler 300, Dodge Charger, Jeep Grand Cherokee, Ford Edge, Chevrolet Traverse, GMC Acadia, and Buick Enclave applications, along with additional BMW, Cadillac, and Lincoln models. For buyers searching by vehicle, Four Seasons 70057 is a relevant replacement for common HVAC electrical connector repairs on Chrysler 300, Dodge Charger, and Jeep Grand Cherokee platforms.

Use this connector when the original harness end no longer maintains a stable electrical path to the blower motor resistor. The 6-terminal layout and blade terminal style support a direct connector repair rather than a full harness replacement in many cases.

Common Problems This Part Can Address

• Blower motor resistor connector melting or heat damage
• Intermittent HVAC blower operation caused by poor terminal contact
• Corroded or loose connector terminals at the resistor harness
• Damaged wiring at the HVAC blower motor resistor plug
• Electrical connection loss in front or rear HVAC blower circuits on listed vehicles

Installation Notes and Tips

Verify the connector shape, terminal count, and wire gauge before installation. Match the vehicle-side connector to the 6-terminal male configuration shown in the fitment data, and confirm whether the application is front, rear, or N/A as listed for your vehicle. Inspect the resistor, terminals, and surrounding wiring for heat damage before completing the repair. Proper terminal seating and secure wire splicing are important for reliable HVAC blower operation.

Quality Assurance

Four Seasons 70057 is part of the Four Seasons Harness Connector line and is cataloged for direct replacement use across confirmed fitments. The part is specified with defined connector geometry, terminal type, and wire sizing to support accurate HVAC electrical repair selection.
