95 Accord EX. Fan comes on when engine is cool, several hours after driving. Next morning, battery is dead. What could be the cause?

 

Cooling fan timer. It's right behind your glovebox (mounted to the brace just about right in the middle). Pull the glovebox down and you will see the black box. If the fans are running at that moment unplug it and if the fans quit then the timer is bad. (you can't miss the box it says "radiator fan timer" right on it).

 

Thanks, I'll give that try.

 

could also be a shorted switch , the one at the end of the top radiator hose toward the block,..also make sure you got planty of coolant in radiator
