Detailed Product Description

The RU-58 blower motor resistor by Standard Ignition is engineered to provide reliable control over the HVAC blower motor speeds in specific GM vehicles. It features a screw attachment method for a firm and stable fit within the HVAC system. The resistor includes a female rectangular connector designed to mate with the vehicle’s wiring harness, featuring one connector cavity and four male blade terminals to ensure proper electrical connection. This part does not come with a wiring harness or mounting brackets, so it is intended for direct replacement of the existing resistor in the HVAC assembly.

Compatible Vehicles and Applications

• Compatible with 1998 Buick LeSabre models requiring a 3-5 speed blower motor resistor
• Fits 1998 Pontiac Bonneville HVAC systems
• Suitable for select Oldsmobile models from the same era

Common Issues Addressed by RU-58 Blower Motor Resistor

• HVAC blower motor stuck on a single speed
• Intermittent or no blower motor operation
• Loss of certain blower speed settings
• Overheating or failure of the blower motor resistor
• Inconsistent airflow from the vehicle’s heating and cooling system

Installation Notes and Tips

Installation requires removing the old blower motor resistor from the HVAC housing and securing the RU-58 resistor using screws. Ensure the female rectangular connector aligns properly with the vehicle’s wiring harness. Since no wiring harness or mounting brackets are included, reuse the existing hardware and connectors. It is recommended to disconnect the vehicle battery before installation to prevent electrical shorts.
