I have a 1990 honda accord ex that dies every night... but when I take out the relay in the fuse pannel that goes to the cooling fan it stops killing my batter so I know its something to do with the fan... now my problem is that I have replace both the relay in the fuse panel and the relay that is on also attached to the rdiator... I am completely lost and can not figure out why it is doing this... any help would be greatly apprieciated...

Replace the Engine Coolant Temperature (ECT) Switch, located on the thermostat cover:

Relays were likely fine.
