Dial in the right cabin airflow with the Standard Ignition HVAC Blower Motor Resistor RU-890. This resistor drops into the blower motor circuit as a direct-fit replacement for the 2018-2019 Mitsubishi Eclipse Cross, the 2014-2019 Mitsubishi Outlander, and the 2014-2019 Mitsubishi Outlander Sport, restoring the control your HVAC fan speeds depend on.
Mounted in the heater/blower circuit, the resistor sets the different fan-speed steps by adding resistance ahead of the blower motor, so each position moves the intended amount of air.
- Fan-speed control: Provides the calibrated resistance that establishes the lower blower speeds.
- Direct-fit replacement: A direct-fit replacement for the listed Mitsubishi applications.
- Signs it may need replacing: Blower works on high only, one or more speeds are dead, or the fan won't run at all — if a failed resistor is the cause, this replaces it.
Diagnose the cause of an inoperative or single-speed blower before replacing, since a switch, connector, or the blower motor itself can produce similar symptoms.
Interchange: Manufacturer part number RU-890 (also RU890).
Frequently Asked Questions
What does the RU-890 do?
It adds calibrated resistance in the blower motor circuit to set the lower fan-speed steps, so each speed position delivers the intended amount of airflow.
Which vehicles does it fit?
It is a direct-fit replacement for the 2018-2019 Mitsubishi Eclipse Cross, 2014-2019 Mitsubishi Outlander, and 2014-2019 Mitsubishi Outlander Sport. See the Buyer's Guide tab to confirm your vehicle.
Why does my blower only work on high speed?
A failed blower motor resistor is a common cause, since it controls the lower speeds. If the resistor is the cause, this part replaces it; verify the fan switch and wiring too.
What is the manufacturer part number?
The manufacturer part number is RU-890 from Standard Ignition.
Should I diagnose before replacing?
Yes. An inoperative or single-speed blower can also come from the fan switch, connector, or the blower motor itself, so confirm the cause before installing this resistor.
