Faulty relay

Question : I BOUGHT a Proton Gen2 four years ago.

It is an automatic transmission and I like the car very much but one thing that bothers me is that sometimes, the radiator fan is still running even when the switch is off and the engine at a stop.

To stop the fan, I have to restart the engine and off it again.

What puzzles me is why the fan is still running although the switch is off ?

I do not dare to let the fan run as I'm not sure when it will stop or affect the battery.

Answer : I am not too sure of the configuration of the fan for this model but often, the second electric fan for the air-cond is thermostatically controlled and can run on even when the ignition is turned off.

However, when the temperature drops sufficiently, the thermostat switch will turn off the fan.

In your case, it sounds like the relay is faulty and sometimes does not release, so keeping the fan running.

Try to locate the relay and replace it if found to be working inconsistently.
