...electric~slide anyone?

Greetings Gents, Have any of you car pros ever heard or experienced this strange occurence: All too often, I have have starting issues with my 92’ Buick LeSabre custom- so I’ve learned by temporarily loosening the positive battery-cable, then re-tightening it back on to the battery, this will usually enable it to start-- however after doing this I’ve noticed the ‘defrost’ button on the console is illuminated and has somehow managed to turn itself on… weird… Any ideas or suggestions would be much appreciated !! Thanks, -TONY

Rather than worry about that, I would clean that cable or replace it. Do both ends of the cable while you are at it.
