Four Seasons 70058 HVAC Blower Motor Resistor Connector

HVAC Blower Motor Resistor Connector

Four Seasons 70058 is a rectangular HVAC blower motor resistor connector built for repair work on vehicle climate control wiring. It uses a male connector body with 4 female terminals, 12-gauge wire, and a 6-inch wire length for direct service on damaged or heat-affected harness ends.

Compatible With Ford, Nissan, Lincoln, and related applications that use a rectangular blower motor resistor connector, including Explorer, F-150, Frontier, and Taurus platforms. Four Seasons 70058 is a practical replacement when the original connector shows melting, corrosion, or terminal damage.

Detailed Description

This connector is used in blower motor resistor circuit repairs where the factory plug has overheated, loosened, or lost terminal contact. The rectangular housing and blade-style terminal design support a secure electrical connection at the HVAC resistor interface. Four Seasons 70058 is listed across many popular truck, SUV, and car platforms, including Ford Explorer, Ford F-150, Nissan Frontier, and Ford Taurus applications. This part cross-references AP Exhaust 645403 for the same application.

Common Repair Uses

• Restores blower motor resistor electrical connection after connector heat damage
• Replaces cracked, brittle, or broken HVAC harness plugs
• Addresses intermittent blower speed operation caused by poor terminal contact
• Corrects corrosion-related resistance in the HVAC control circuit
• Supports repair of melted wiring at the resistor connector

Installation Notes and Tips

Verify connector shape, terminal count, and wire gauge against the original part before installation. Match the vehicle harness and resistor plug style carefully, especially on Ford Expedition, Lincoln Navigator, and Nissan Frontier applications where connector notes vary by model year. Inspect the surrounding wiring for heat damage and replace any compromised terminals or wire sections before final connection.

Quality Assurance

Four Seasons 70058 is built as a service replacement connector for HVAC electrical repairs and is cataloged with confirmed interchange references for application matching. Use the vehicle fitment details to confirm the correct connector style for your specific model year.
