Standard Ignition S-719 HVAC Blower Motor Resistor Harness

HVAC Blower Motor Resistor Harness for Ford and Mercury

Standard Ignition S-719 is an HVAC blower motor resistor harness built for repair work on select Ford and Mercury vehicles. It uses a 1 male connector with 4 female blade terminals and 4-wire construction to restore a secure electrical connection where the original pigtail has failed.

Standard Ignition S-719 is a practical replacement for damaged, heat-affected, or corroded blower motor resistor connectors on applications such as the Ford Focus, Ford Contour, Mercury Mystique, and Mercury Cougar.

Key Features

• HVAC blower motor resistor harness for electrical repair
• 1 male connector with 4 female 4-blade terminals
• 4-wire pigtail assembly for direct connector replacement
• Built with high-grade materials for conductivity and connection integrity
• Standard Ignition S-719 for select Ford and Mercury HVAC systems

Application Details

This harness is used to replace a damaged blower motor resistor connector in HVAC systems where heat, vibration, or age has weakened the original plug. It is a direct-fit style repair part for vehicles including 1995-2000 Ford Contour, 1995-2000 Mercury Mystique, 1999-2002 Mercury Cougar, 2000-2007 Ford Focus, 2011 Ford Focus, and 2010-2013 Ford Transit Connect.

This part cross-references Dorman - TECHoice 973-303 and Four Seasons 37270 for the same application.

Common Problems It Can Help Solve

• Melted or heat-damaged blower resistor connector
• Intermittent HVAC blower motor operation
• Loose or corroded electrical connection at the resistor
• Loss of blower speed control caused by poor terminal contact
• Failed pigtail wiring at the HVAC resistor circuit

Installation Notes and Tips

Verify connector style, terminal count, and wire layout against the original harness before installation. Match the vehicle application carefully, especially on Ford Focus, Ford Contour, Mercury Mystique, and Mercury Cougar models where HVAC connector details can vary by year and configuration. Proper terminal seating and secure splicing are important for a stable repair.
