Take charge of your cabin fan speeds with this Four Seasons switch, part number 20185, cataloged as an HVAC Blower Motor Resistor / Switch for the front blower circuit. It installs as a direct-fit replacement for the 1997-2004 Mitsubishi Montero Sport. See the "Vehicles it fits" section for engine-specific details.
The blower motor resistor works with your fan-speed control. It helps set the front blower motor's speed by controlling the current supplied to the motor at the lower fan settings. The part is listed under both names, HVAC Blower Motor Resistor and Switch.
- OE-style connectors: Mate with the vehicle's wiring harness connection.
- Quality contacts: Help maintain proper electrical conductivity through the circuit.
- Vehicle-specific application: Built for the listed applications rather than as a universal unit.
- Precision engineered and tested: Four Seasons engineers and tests the part, drawing on more than 50 years of mobile A/C experience.
Signs the resistor may need replacing include a blower that runs only on its highest setting, or one or more fan speeds that no longer work. A faulty switch, wiring or blower motor can cause similar symptoms, so diagnose the cause first. If the resistor is at fault, Four Seasons 20185 replaces it.

Frequently Asked Questions
What does the Four Seasons 20185 do?
It helps set the front blower motor's speed by controlling the current supplied to the motor at the lower fan settings of the HVAC system.
Does it fit the 1997-2004 Mitsubishi Montero Sport?
Yes, it is a direct-fit replacement for the 1997-2004 Mitsubishi Montero Sport. Check the "Vehicles it fits" section for engine-specific details.
What are signs a blower motor resistor may need replacing?
Common signs include a blower that runs only on high, or fan speeds that stop working. A bad switch, wiring or blower motor can cause similar symptoms, so diagnose the cause first.
Why is it listed as both a switch and a blower motor resistor?
The catalog classifies part 20185 as a switch, while Four Seasons describes it as an HVAC Blower Motor Resistor, so it is listed under both names.
What kind of connectors and contacts does it have?
It uses OE-style connectors. Four Seasons pairs them with quality contacts intended to maintain proper electrical conductivity.
