when i turn the engine off and pull out the keys on the ignition, the radiator fan apparently ran on different times on its own, rendering my battery without power.

the next morning when i tried to start the engine, there was only the clicking sound. so we had to push the tsikot to jumpstart it (kadyot) and have the battery charging again on high revving.

i found a relay that became too hot and had it replaced. all else seems to function normally except for the fan.

i've also noticed that in some occasions, when i press the keys to the ignition and see the handbrake light on, the radiator fan turns on as well.

what could seem to cause this issue? this happened to me on two straight mornings now.
