I've got a possible battery drainage issue, which might have narrowed it down to my motor blower (heater)40A fuse. The fuse it self is really hot with a slight burn mark on the face for the fuse. Is this normal or is it sucking power from the battery. It's been 6 hours since I last drove and didn't use the aircon. Alternator is good and battery is less then a year. Any suggestions would be great.
