The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.
Over time serpentine belts stretch, crack, and the ribs that ride on the accessory pulleys being to wear smooth. A squealing noise that increases with engine speed or as engine driven accessories are turned on may be noted. The noise is caused by the belt slipping on the pulleys, insufficiently driving them. Ineffective air conditioning, a battery warning light, or intermittent power steering assist can result from this.
The bad thermostat can cause two different sets of problems, depending on whether it's stuck open or stuck closed.
A thermostat that is stuck open can cause the engine to run colder than normal and turn on the check engine light. It may also cause poor fuel mileage and the heater to blow cool air.
A thermostat that is stuck closed will cause the vehicle to overheat. If a new thermostat doesn't resolve engine temperature problems, the cooling system needs to be checked for other issues.

When the engine coolant temperature sensor fails, it will send inaccurate information to the vehicle’s computer, causing the computer to react to false operating conditions. This will cause the engine to consume more fuel than normal, depleting fuel mileage, and causing black, sooty smoke from the engine under moderate to heavy acceleration. The check engine light will illuminate, and on-board diagnostic trouble codes may be stored for exhaust and emission system failure, fuel delivery system failure, and engine cooling system failure. Overheating may also occur, as the coolant sensor may be leaking fluid out of the engine, creating a an air pocket in the system.
When the radiator fans stop functioning properly, the engine temperature will rise. The spike in temperature will be highest when the vehicle is idling at a stop, but should subside once the vehicle begins moving again.
Additionally, the air conditioner typically won't blow as cold. This is because the air from the radiator fans also blows across the air conditioning condenser, so when the fans fail, both systems suffer.
You'll also usually see the check engine light and notice a drop in fuel economy. It's possible the fan will start making noise if it's failing, as well.
To effectively diagnose a non-functioning radiator fan in a 2014 Dodge Grand Caravan, start with the simplest checks before moving on to more complex diagnostics. Begin by inspecting the fuses located in the main fuse box under the front hood, specifically fuses J12 and J19, which are responsible for powering the radiator fan motor and fans. If the fuses are intact, proceed to examine the Low Speed Radiator Fan Relay, located on the right side of the fuse box. Testing the relay can be done by swapping it with a known good relay or using a multimeter to check for voltage and continuity. If the relay is functioning, check the electrical connections and wiring for any signs of damage or resistance, particularly in the Fused B+ circuit and the Rad Fan Low Speed Control circuit. Next, test the cooling fan motor directly by applying power from a 12-volt source to see if it operates. Additionally, ensure that the engine coolant temperature sensor is working correctly, as a faulty sensor can prevent the fan from activating. Finally, consider using a scan tool to check for any diagnostic trouble codes that may provide further insight into the issue. By following this structured approach, you can systematically identify and resolve the problem with the radiator fan in your vehicle.
When troubleshooting the radiator fan issues in a 2014 Dodge Grand Caravan, it's essential to consider several common problems that could lead to fan failure. Start by checking the fuses, specifically Fuse J12 and Fuse J19, as a blown fuse can completely cut off power to the fan. If the fuses are intact, the next step is to inspect the Low Speed Radiator Fan Relay, which can be tested by swapping it with a known good relay. Additionally, examine the wiring and electrical connections for any signs of damage or corrosion, as these can create high resistance or open circuits that prevent the fan from operating. The Totally Integrated Power Module (TIPM) is another critical component to consider; if it has faulty connections or internal failures, it may not send the necessary signals to the fan. Furthermore, the cooling fan control module should be checked, as a malfunction here can disrupt the communication between the control module and the fan relay. Lastly, while less common, mechanical issues such as a failing radiator or thermostat can indirectly affect fan operation, so keep an eye out for any related symptoms like overheating or coolant leaks. By systematically addressing these potential issues, you can effectively diagnose and resolve the radiator fan problems in your vehicle.
Repairing the non-functioning radiator fan in a 2014 Dodge Grand Caravan is an urgent matter that should not be overlooked. A malfunctioning fan can lead to severe engine overheating, which poses a significant risk of damaging vital engine components and can result in costly repairs or even complete engine failure. Additionally, a faulty fan can disrupt the coolant system, leading to low coolant levels or air pockets that further exacerbate overheating issues. This not only increases repair costs but also creates immediate safety concerns, as an overheating engine can cause a loss of power or even stall while driving, putting you and others at risk. Addressing this issue promptly is essential to prevent further damage to critical components like the head gasket or engine block, which can be extremely expensive to repair. If you find yourself unable to make immediate repairs, consider temporary solutions, such as manually controlling the fan with a battery connection, to mitigate risks until a proper fix can be implemented. Prioritizing the repair of your radiator fan is crucial for maintaining vehicle safety and performance.
