Dorman Engine Cooling Fan Motor Relay 921-300 — Direct-Fit Plug-and-Play Replacement for Chrysler & Dodge

The Dorman 921-300 Engine Cooling Fan Motor Relay is a direct-fit replacement relay designed to restore reliable electric cooling-fan operation on specified Chrysler and Dodge vehicles.

This relay replaces the factory unit that controls the engine cooling fan circuit. Built with factory-style connectors and durable materials, it is designed and tested to match the original part's function so you can return the cooling system to proper working order without modifying wiring or connectors. Before ordering, use the vehicle-fit tool to confirm compatibility with your year, make, and model.

How does this relay restore cooling-fan operation?

The relay acts as an electrical switch that lets the engine control module or thermal sensor power the cooling fan only when needed. A faulty relay can prevent the fan from turning on or cause it to run continuously; swapping in a properly tested replacement restores correct on/off control without altering the rest of the system.

• Matches original relay function for key model years of Chrysler Town & Country, Voyager, Dodge Grand Caravan, and Journey
• Factory-style terminals fit existing harnesses—no splicing required
• On-vehicle testing verifies switching performance before shipping

What makes the Dorman 921-300 different from a generic relay?

This unit is manufactured to mirror the original equipment relay's form and connectors so installation is straightforward. Components and assembly are selected to withstand automotive temperature and vibration conditions, which helps ensure longer service life than many off-the-shelf, non-vehicle-specific relays.

• Durable construction for automotive environments
• Factory-style connector layout reduces fitment risk
• Quality-tested on vehicles to confirm switching reliability

How easy is it to install in my vehicle?

Installation is simple for anyone familiar with basic under-hood or relay-box servicing. The relay uses the same mounting and connector style as the original, so it typically slides into the factory relay socket with no extra tools or wiring changes.

• Plug-and-play replacement—no cutting or splicing
• Fits into the factory relay block or bracket used in listed vehicles
• Suitable for DIY replacement or quick shop swap
