Detailed Product Description

The RU-665 blower motor resistor from Standard Ignition is engineered to provide reliable control over the HVAC blower motor speeds in Subaru Legacy vehicles. Featuring a screw attachment method, it ensures a firm and stable fit within the HVAC system. The resistor includes a female rectangular connector with one cavity, designed to mate with the vehicle’s wiring harness. It supports multiple blower speeds, ranging from three to five, allowing for precise airflow adjustments inside the cabin. The four male blade terminals provide secure electrical connections, operating at 12 volts to match the vehicle’s electrical system requirements. This resistor does not come with a wiring harness or mounting brackets, so it is intended for direct replacement of the existing component.

Common Applications and Issues Resolved

• Restores proper blower motor speed control in Subaru Legacy HVAC systems
• Eliminates blower motor stuck on one speed or no speed
• Fixes inconsistent or intermittent blower operation
• Addresses overheating or failure of the blower motor resistor
• Improves overall HVAC system reliability and comfort

Installation Notes and Tips

Installation of the Standard Ignition RU-665 blower motor resistor requires removal of the old resistor from the HVAC housing, typically secured by screws. Ensure the vehicle’s ignition is off and the battery is disconnected before beginning installation. The female rectangular connector should be carefully aligned and connected to the vehicle’s wiring harness. Since no wiring harness or mounting brackets are included, reuse the existing hardware and connectors. Verify all electrical connections are secure and test the blower motor speeds after installation to confirm proper operation.
