Standard Motor Products RU588 HVAC Blower Motor Resistor

The Standard Motor Products RU588 HVAC Blower Motor Resistor is a precision-engineered replacement component designed to restore variable speed control to your vehicle's heating and air conditioning system. This resistor controls the electrical current flowing from the fan switch to the blower motor, allowing you to adjust fan speeds for optimal climate comfort.

Key Features:

• Premium copper electrical connectors ensure precise resistance values and longer service life
• 12-volt operation with 4-terminal blade-type connector configuration
• Controls 3 to 5 blower motor speeds for optimal HVAC performance
• Female rectangular connector with male terminal gender and screw-in mounting
• Engineered for seamless integration with OEM HVAC systems
• Manufactured in TS16949 and ISO9001 certified facilities for quality assurance
• Extensively tested to ensure reliable performance in all operating conditions

This resistor is specifically designed for Ford and Mercury applications. When your blower motor only works on high speed or stops functioning at certain settings, a failed resistor is often the cause. The RU588 restores proper fan operation, helping optimize passenger comfort and HVAC system efficiency. Hardware and wiring harness not included; uses screw-in attachment method.
