Product Details and Specifications

The RU-874 blower motor resistor from Standard Ignition is specifically designed for Dodge Dart models, providing a direct replacement for the original part. It features a screw attachment method that ensures a firm and stable mounting within the HVAC system. The resistor includes a female rectangular connector with two cavities, accommodating five male blade terminals to maintain consistent electrical contact. This part supports multiple blower speeds, ranging from three to five, allowing for precise climate control adjustments. Note that this resistor does not come with a wiring harness or mounting brackets, so existing hardware will be reused during installation.

Common Applications and Problem Resolution

This HVAC blower motor resistor is used to regulate the speed of the blower motor in the heating and air conditioning system of the Dodge Dart. It addresses several common issues, including:

• Blower motor stuck on a single speed or not changing speeds
• Intermittent blower operation or failure to turn on
• Overheating or electrical resistance failure in the blower circuit
• Loss of HVAC system airflow control
• Unusual blower motor noise related to resistor malfunction

Installation Notes and Tips

Installation of the RU-874 blower motor resistor requires removal of the old resistor from the HVAC housing, typically secured by screws. Ensure the connector is properly aligned with the female rectangular port and that all five blade terminals make solid contact. Since no wiring harness or mounting brackets are included, retain and reuse the original hardware. Verify blower motor operation across all speeds after installation to confirm proper function.
