Product Details and Specifications

The RU-370 blower motor resistor from Standard Ignition is built to meet OEM specifications for Mitsubishi Lancer and Outlander HVAC systems. It features a screw attachment method for a firm and reliable fit. The resistor includes a female rectangular connector with one cavity, designed to interface with the vehicle’s wiring harness. It supports 3 to 5 blower motor speeds, allowing precise control of the HVAC fan. The four male blade terminals provide secure electrical connections, operating at a standard 12-volt system voltage. This resistor does not come with a wiring harness or mounting brackets, so it is intended for direct replacement using existing vehicle components.

Common Applications and Problem Resolution

• Restores blower motor speed control in Mitsubishi Lancer and Outlander HVAC systems
• Resolves issues with blower fan stuck on one speed or not working at all
• Fixes intermittent blower motor operation or inconsistent fan speeds
• Addresses electrical resistance failures causing HVAC blower malfunction

Installation Notes and Tips

Installation of the Standard Ignition RU-370 blower motor resistor requires removal of the old resistor from the HVAC housing, typically secured by screws. Ensure the vehicle’s ignition is off and the battery is disconnected before beginning installation. The female rectangular connector should be carefully plugged into the vehicle’s wiring harness, verifying a snug fit. Since no wiring harness or mounting brackets are included, reuse the existing hardware and connectors. Confirm proper blower motor operation after installation by cycling through all fan speeds.
