I have got a problem with both engine and radiator fans. The normal way of operating is when the coolant temperature reaches a certain level the two fans starts and become off after some time. This procedure continues like this. My problem is these fans are running continuously even when the engine is off and can continue up to an hour until I remove the connector to the fans. The time when the fans become off temporally is when I put the key on on position and when I put it back to off position again the fans start working.
Can anyone advise how to sort out this problem?
