Detailed Product Description

The RU-63 blower motor resistor by Standard Ignition is engineered to provide reliable control over the HVAC blower motor speeds in compatible vehicles. Its screw attachment method allows for a firm and stable fit within the HVAC system. The resistor features a female rectangular connector designed to interface with the vehicle’s wiring harness, although the harness itself is not included. Equipped with four male blade terminals, this resistor supports multiple blower speeds ranging from three to five, accommodating various climate control settings.

This part is specifically compatible with Chevrolet Lumina APV, Lumina Van, Oldsmobile Silhouette, and Pontiac Trans Sport models, ensuring proper fitment and function. The absence of included hardware and mounting brackets means installation requires existing components or separately sourced parts.
