The fan defaults to an always ON condition anytime a code is set or the SES light comes on. Pull the codes and find out which one is setting. You must start there.

Like Danno has said, pull the codes and post them so we will have a better idea of what is wrong with your car.

The fan shouldn't be coming on when the SES light comes on unless the ECM is entering limp home mode
