Keep your electric engine cooling fan properly controlled with the Four Seasons Engine Cooling Fan Controller / Relay 36143, a pulse width modulated fan controller designed to vary fan speed by rapidly pulsing power to the fan motor. It fits many vehicles, among them the 2003-2004 Jeep Wrangler, 2001-2009 Dodge Grand Caravan and 2001-2009 Chrysler Town & Country, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list. This part is listed under both names, engine cooling fan controller and relay.
- Precision engineered: built for vehicle-specific applications.
- OE-style molded connectors: connect to the vehicle's wiring harness.
- Quality contacts: help maintain proper conductivity.
- Four Seasons experience: engineered and tested with the aim of years of trouble-free operation, drawing on more than 50 years of mobile A/C experience.
Signs this part may need replacing include a cooling fan that won't come on, won't change speed or won't shut off, engine temperature climbing at idle or in traffic, and weak A/C cooling at idle. If a failed fan controller is the cause, the 36143 replaces it. The fan motor, fuses, wiring and sensors can cause similar symptoms, so diagnose the cooling fan circuit before replacing parts.

Frequently Asked Questions
What does a pulse width modulated fan controller do?
It controls the electric engine cooling fan by rapidly pulsing power to the fan motor. This lets the fan run at varying speeds rather than only on or off.
Can I use this as a 2003-2004 Jeep Wrangler cooling fan relay?
Yes. The 36143 is a direct-fit replacement for the 2003-2004 Jeep Wrangler and also fits the 2001-2009 Dodge Grand Caravan and 2001-2009 Chrysler Town & Country. See the "Vehicles it fits" section for the full list.
Is this the same part as a 2003-2004 Jeep Wrangler starter relay?
No. Four Seasons 36143 is an engine cooling fan controller listed under the relay part type. It controls the cooling fan, not the starter.
What features does the Four Seasons 36143 have?
It is precision engineered for vehicle-specific applications. It has OE-style molded connectors and quality contacts that help maintain proper conductivity.
What are signs the cooling fan controller may need replacing?
Signs may include a cooling fan that won't run, won't change speed or won't shut off, or engine temperature rising at idle. The fan motor, fuses and wiring can cause similar symptoms, so diagnose first.
