Dorman 645-707 HVAC Blower Motor Resistor Connector

HVAC Blower Motor Resistor Connector

Dorman 645-707 is an HVAC blower motor resistor connector built to replace an original connector damaged by heat or corrosion. It uses corrosion-resistant terminals to help restore a dependable electrical connection for the blower motor circuit.

Compatible With Volkswagen Beetle, Jetta, Golf, Van, Derby, and Clasico models with manual temperature control, as well as Audi TT and TT Quattro applications with manual temperature control. This Dorman 645-707 connector is a direct-fit electrical repair solution for common HVAC blower motor resistor connector failures.

Key Features

• Replacement HVAC blower motor resistor connector for damaged OE plugs
• 12-gauge wire construction for blower motor circuit repair
• 4-wire female blade terminal design
• Tin brass terminals with tin plating for corrosion resistance
• 13-inch overall length for repair flexibility
• Includes pigtail and butt connectors for wiring repair

Detailed Description

This Dorman HVAC blower motor resistor connector is designed for vehicles that use manual temperature control and need a replacement for a heat-affected or corroded connector. The female blade terminals and tin-plated brass terminal material are selected to maintain a stable electrical connection in the blower motor resistor circuit. If your fan motor is no longer operating correctly, Dorman 645-707 provides a practical repair path for restoring HVAC blower function.

This part cross-references OE part number 1J0972754 for the same application. It is a strong fitment match for Volkswagen Jetta, Volkswagen Beetle, and Audi TT blower motor resistor connector repairs where the original connector has overheated or deteriorated.

What It Helps Fix

• Blower motor not working due to a damaged resistor connector
• Intermittent HVAC fan operation caused by corrosion at the connector
• Heat damage at the original blower motor resistor plug
• Loose or unreliable electrical contact in the HVAC circuit
• Connector failure on manual temperature control systems

Installation Notes and Tips

Verify the vehicle uses manual temperature control before ordering. Match the original connector style, wire gauge, and terminal layout to the existing harness before splicing. Use proper wiring repair practices when joining the pigtail to the vehicle harness, and inspect the blower motor resistor and surrounding wiring for heat damage before completing the repair.
