Cooling fans may not turn off due to several reasons, such as a malfunctioning temperature sensor that incorrectly signals the need for cooling, or a problem with the fan control module that fails to respond to the system's requirements. Additionally, continuous operation can occur if the system is still overheating or if there is an issue with the thermostat. It's also possible that the fans are operating as designed, especially in high-load conditions. Checking for error codes and inspecting the relevant components can help diagnose the issue.
You are correct, they do turn on and off in alliance with engine temp
Some cooling fans will stay running even if the car is shut off to cool down the motor. Once the fans thermostat gets tripped to shut off, the fan will continue to run.
No, the electric cooling fans turn on and off by a signal from the coolant temp sensor. The coolant level sensor only illuminates the low coolant light when you are low on coolant.
The most common fault are that the fuse has blown or the thermostat is faulty.
check your relay for the cooling fan and fuelpump
Do they work when you turn the A/C or Defroster on? If so it could be temperature sensor If not it could be fuse
I too am having the exact same problem!
2001 VW jetta the radiator cooling fans run all the time they run soon you turn the ignition switch on with cold engine. if the engine is hot and you turn the ignition switch off the stay on till battery goes dead.
Turning my ignition on and wont turn off because it is faulty.
If it is the heater fan, there is a short in the wiring. If you mean the cooling fan on the radiator, it is normal with some vehicles.
My 1965 MGB will not turn off when turn the key to off .
IT COULD BE ONE OF THE COOLING FANS RUNNING, BAD RELAY.
