My engine, brake etc warning lights glow when I turn the key off and the new battery is run down in AM. Obviously looks like I need a new ignition switch but long ago read a page that said if a certain fuse was blown it would allow the current to bypass the swithch with the same effect. Can't find that article and don't want to waste a lot of time and money on a new switch if this is true. Have owned cars for 50 years and this is the only time this has happened....course never kept a car for 300,000 miles before. ('93 LC) thanx
