Do the fans run even with the ignition turned off?

As a temporary solution, find the fuse for the cooling fans and pull it. That will stop the fans and maybe prevent the battery from being drained.

YOU CANNOT DRIVE THE CAR WITH THE FANS DISCONNECTED. This is just to save the battery while the car is not in use.

When it’s running, take the car to a parts store or a mechanic and have the computer scanned for trouble codes. That should give you some idea why the CEL is on. Report back.

It’s probably as simple as a Temperature Sensor switch.
