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
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
