91 Legend cooling fan turns on by itself
The cooling fan will turn on randomly with the engine off. Sometimes in the middle of the night it will start and run until the battery is dead.
Any ideas what might cause this?

Replace the cooling fan engine temp sensor switch, this may be the cause.
Good place to start is the temp. sending unit that turns the fan on and off, usually located in or near the bottom of the radiator. On many cars, the is is how the system works, but only until the engine cools down, and it should never run the battery down. I suspect the temperature sending unit is shorting out.
