Detailed Product Description

The RU-93 blower motor resistor from Standard Ignition is engineered to provide reliable speed control for HVAC blower motors in various Chrysler, Dodge, and Plymouth minivans and wagons. Its screw attachment method allows for a firm and stable fit within the HVAC system. The resistor features a female rectangular connector with a single cavity, designed to mate with the vehicle’s wiring harness. It includes five male blade terminals that facilitate electrical connections necessary for controlling multiple blower speeds, ranging from three to five settings depending on the vehicle’s HVAC system configuration.

This resistor does not come with a wiring harness or mounting brackets, so it is intended for direct replacement in vehicles where the original hardware is retained. The absence of a wiring harness means installation requires connecting to the existing vehicle wiring, making it suitable for professional or experienced DIY installation.
