Chrysler Voyager Engine Cooling Fan Relay Kits

Chrysler Voyager Engine cooling fan relay kits

Starting at $59.95, AutoBuffy stocks 6 engine cooling fan relay kits from Mopar, Four Seasons, and Dorman. The cooling fan relay is an electrical switch that tells your radiator or condenser fan to run when the engine reaches operating temperature. When it fails, the fan stops receiving the signal to turn on, leading to overheating and potential engine damage.

Signs your Chrysler Voyager needs a new engine cooling fan relay kit

  • Engine temperature gauge climbs into the red at idle or in slow traffic, but returns to normal at highway speed where airflow cools the radiator without the fan
  • Cooling fan never turns on — you can verify this by letting the engine idle until warm and listening or visually checking the fan blade
  • Cooling fan runs at full speed constantly from startup, even when the engine is cold, indicating the relay is stuck closed
  • Air conditioning performance drops noticeably at idle because the condenser fan, controlled by the same relay circuit, is not pulling air through the A/C condenser
  • A burned smell or visible scorch marks on the relay housing or surrounding fuse box cavity, caused by excessive current passing through a failing contact
  • Scanner shows a coolant temperature sensor reading within normal range yet the fan never activates, pointing to the relay rather than the sensor or fan motor itself

Which engine cooling fan relay kit should you buy for your Chrysler Voyager?

Cooling fan relay kits vary by whether they include just the relay, or a complete kit with the relay, pigtail wiring connector, and mounting hardware. Matching the relay's amperage rating and connector style to the original is the most important factor — an undersized relay will overheat and fail quickly, while a mismatched connector means the kit won't plug in without modification.

OEM-Equivalent Relay Only
Best for
Straightforward swap when the existing wiring harness and connector are in good condition
What you get
Single relay matched to factory amperage rating and connector footprint; most affordable entry point
Complete Kit with Pigtail Connector
Best for
Vehicles where heat or corrosion has damaged the connector housing or wiring near the relay
What you get
Relay plus pre-wired pigtail so you splice into known-good wire rather than risk a bad connection at the old terminal
Heavy-Duty / Upgraded Relay
Best for
Vehicles used for towing, in hot climates, or with a history of repeated relay failures
What you get
Higher-rated relay contacts that handle thermal cycling better; reduces likelihood of the same failure recurring
Multi-Relay Kit (Fan + A/C Relays)
Best for
Situations where both the cooling fan relay and the A/C condenser fan relay are suspect or have the same part number
What you get
Two or more matched relays servicing the entire cooling and A/C fan circuit in one purchase, preventing a repeat repair visit

Replacing an engine cooling fan relay kit on a Chrysler Voyager

Easy⏱ 15–45 minutesFuse puller or needle-nose pliersMultimeterWire stripper and crimping tool (if installing a pigtail kit)Screwdriver setFlashlight or work light

Start by locating the correct relay in the fuse and relay box — the owner's manual or lid diagram will identify it by position. Pull the old relay straight out, confirm the replacement matches the terminal layout and amperage rating, and press the new relay firmly into the socket until it seats. If installing a pigtail kit, disconnect the battery before cutting into the wiring harness, match wire colors or use a wiring diagram, and use soldered or crimp connections rated for automotive use rather than simple twist-and-tape joints.

Frequently asked questions

How much does it cost to replace engine cooling fan relay kits on a Chrysler Voyager?
Parts start at $59.95 at AutoBuffy. The relay itself is inexpensive, and most of the cost in a shop repair is labor — typically under an hour of work. Doing it yourself keeps total cost close to the part price alone, making this one of the better DIY cooling system repairs.
Can I drive my Chrysler Voyager with a bad cooling fan relay?
You should not drive with a failed cooling fan relay beyond what is necessary to reach a repair location. At idle or in traffic the engine relies on the electric fan to prevent overheating. Continued driving risks warping the cylinder head or causing head gasket failure, both of which are far more expensive than replacing the relay.
How do I test the cooling fan relay on my Chrysler Voyager before replacing it?
The fastest test is the swap test: locate an identical relay elsewhere in your fuse box, swap it with the cooling fan relay, and see if the fault moves with it. You can also use a multimeter to check coil resistance across the relay's control terminals and verify continuity across the load terminals when 12V is applied to the coil.
Will a bad cooling fan relay affect the air conditioning on my Chrysler Voyager?
Yes, in many cases it will. On most vehicles the same relay — or a closely related one in the same circuit — controls the condenser fan that cools the A/C system. If that fan stops running, refrigerant pressure climbs and the A/C system either blows warm air or the pressure switch shuts the compressor off as a protective measure.
How long does a cooling fan relay last on a Chrysler Voyager?
Cooling fan relays are solid-state switches with no serviceable interval, but they typically last many years under normal conditions. Heat, vibration, and high current draw accelerate wear on the internal contacts. Relays mounted close to the engine or in poorly ventilated fuse boxes tend to fail sooner than those in cooler locations.
Is the cooling fan relay the same part as the cooling fan resistor or fan motor on my Chrysler Voyager?
No, they are separate components. The relay is an electrically operated switch that completes the high-current circuit to the fan. The resistor (where used) controls fan speed by adding resistance to the circuit. The motor is the mechanical component that spins the blade. A relay kit only addresses the switching function, not motor or speed-control faults.
