Standard Motor Products RU1003 HVAC Blower Motor Resistor 4-Terminal

The Standard Motor Products RU1003 is a direct-fit replacement HVAC blower motor resistor engineered specifically for Honda applications. The blower motor resistor regulates electrical current between the fan speed switch and the blower motor, enabling precise multi-speed fan control for your vehicle's heating and air conditioning system.

Key Features:

• 4-terminal connector for direct OE-style plug-in installation
• Premium copper electrical connectors deliver more precise resistance values and extended service life
• Designed to meet or exceed original equipment specifications for fit, form, and function
• All-new construction — contains no remanufactured components
• Manufactured in IATF 16949-certified North American facilities
• Every unit is sample-tested for current draw, resistance, and RPM, then validated through rigorous 48-hour load tests

A faulty blower motor resistor is a common cause of inoperative fan speeds — often resulting in the blower working only on the highest setting or not at all. The RU1003 restores full variable-speed blower motor operation, bringing back proper airflow control for both heating and air conditioning. Designed for a straightforward, no-modification installation.
