There are a few reasons why the radiator fan on your 2010 Jeep Liberty might be running with the ignition off. Here are some of the most common causes:
Faulty cooling fan relay: The cooling fan relay is responsible for sending power to the fan when the engine is running. If the relay is faulty, it can keep the fan running even after the engine has been turned off.
Faulty cooling fan switch: The cooling fan switch is responsible for sending a signal to the relay when the engine temperature reaches a certain level. If the switch is faulty, it can keep the fan running even when the engine is cold.
Low coolant level: If the coolant level in your Jeep Liberty is low, the radiator fan may run to help cool the engine.
Dirty radiator: If the radiator is dirty, it can restrict airflow and cause the engine to overheat. The radiator fan may run to help cool the engine.
Faulty thermostat: If the thermostat is faulty, it can prevent the engine from reaching its normal operating temperature. This can cause the radiator fan to run more often than necessary.
If you notice that the radiator fan on your Jeep Liberty is running with the ignition off, it's important to have it checked by a qualified mechanic to determine the cause. Running the fan for extended periods of time can damage the fan motor and other components in the cooling system.
Here are some tips to help you troubleshoot the problem:
Check the coolant level. If the coolant level is low, fill it up to the correct level.
Inspect the radiator for signs of dirt or debris. If the radiator is dirty, clean it with a radiator cleaner.
Check the thermostat. If the thermostat is faulty, replace it.
Have the cooling fan relay and switch tested by a qualified mechanic.
If you've checked all of these things and the radiator fan is still running with the ignition off, then the problem may be more serious and you'll need to take your Jeep Liberty to a mechanic to have it diagnosed.
