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.
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.
Turning my ignition on and wont turn off because it is faulty.
IT COULD BE ONE OF THE COOLING FANS RUNNING, BAD RELAY.
It is probably your cooling fans. These are electric and may run with the engine turned off. It is probably your cooling fans. These are electric and may run with the engine turned off.
