Product Details and Specifications

The Standard Ignition RU-234 blower motor resistor is built to meet OEM specifications for Mazda B-series trucks. It features a rectangular female connector with two cavities and five male blade terminals, ensuring a reliable electrical connection. The resistor supports multiple blower speeds, ranging from 3 to 5, allowing for precise control of the HVAC blower motor. Designed for a 12-volt system, this resistor uses a screw attachment method for mounting, providing a secure and stable fit without the need for additional hardware or wiring harnesses.

Common Applications and Problem Resolution

This HVAC blower motor resistor is used to regulate the speed of the blower motor in Mazda B2000, B2200, and B2600 trucks. It addresses several common HVAC issues, including:

• Blower motor stuck on a single speed or not working at certain speeds
• Intermittent blower motor operation or inconsistent airflow
• Complete failure of the blower motor to operate
• Overheating or electrical resistance problems within the blower motor circuit

Installation Notes and Tips

Installation of the RU-234 resistor requires removal of the old resistor from the HVAC housing, typically secured by screws. Ensure the vehicle’s battery is disconnected before installation to prevent electrical shorts. The rectangular female connector should be carefully aligned with the male blade terminals to avoid damage. Since no wiring harness or mounting brackets are included, reuse existing hardware and connectors from the original resistor. Verify proper blower motor operation after installation by testing all speed settings.
