Most likely cause is a bad sensor, most fans use a temp sensor to tell it to turn on when it reaches a certain temp. Is your car overheating?

Why does my fan keep running in my 2003 Volvo S 60 after the car is off?


It can be faulty fan relay.The relay is not turning the system off.Or its wire short issue.Even with ignition off ,the fan relay is getting power so its not letting the fan to turn off.Bypass the fan control relay and see if still the fan works with ignition off or not.

Fan will not turn off


which fan? Interior fan, or radiator cooling fan? Is it the radiator cooling fan, or the fan controlled by the air-conditioning?

Run the vehicle, turn on and off the air-conditioning to identify which of the fans in the engine bay is the one triggered by the air-con and which is the primary cooling fan.
If the primary cooling fan is permanently engaged, then first try replacing it's relay as it may have fused closed.

Cooling fan burned up


Get a new fan motor and blade from GM or from an aftermarket supplier.

GM parts are usually better than the aftermarket ones, though for fit and functioin.

May also look into checking the relays and harness. If the terminals of the fan show they are getting current, then the motor will have to be replaced if not turning or obviously burnt.

Good luck on this repair.

Inspect/Replace

CAUTION
The fan that draws cool air across the radiator can be driven by either a belt or electricity. Rotating fans can be dangerous. Some are controlled by an automatic switch and can start unexpectedly. When working on electric fans, keep in mind that electric cooling fans should be disconnected when working around them.
When replacing a radiator fan motor, always refer to the vehicle's service manual. The following is a general guide for cooling fan replacement.

  • Disconnect the negative battery terminal at the battery. This is necessary on vehicles using electric fans, but some vehicles may require the relocation of the charging system components.
  • Drain the cooling system.
  • Loosen or remove the hose clamps, then remove the upper and lower hoses from the radiator.
  • Disconnect the transmission cooling lines and plug them off, if equipped.
  • Disconnect the electric fan motor connector, if equipped.
  • Remove the fasteners attaching the fan module to the radiator.
  • On some vehicles equipped with air conditioning systems, it may be necessary to discharge the system. This is the case if the radiator and condenser can not be separated in the vehicle.
  • Remove the upper radiator cross member or mounts.
  • Disconnect and plug the air conditioning lines at the condenser, if needed.
  • Remove the radiator and fan module as one unit if possible.
  • Separate the fan module from the radiator.
  • If required, separate the radiator from the condenser.
  • Remove the old fan module.
  • Install the new fan module onto the radiator.
  • Reattach the fasteners attaching the fan module to the radiator.
  • If equipped, connect the electric fan motor connector.
  • Reinstall the radiator.
  • Refill the cooling system.

Dodge Caravan is notorious for failure of the electronic cooling fan control module (AKA cooling fan relay). This is not a "relay", it is a solid-state control unit, but many people call it a relay anyway.
It is mounted on the inside of the left frame rail just behind the radiator. You have to look up from UNDER the vehicle to see it. It looks like the picture below. The picture shown is very close to actual size.
