Having problems with your 1991 Lincoln Mark VII ?
Interior lighting when I insert the key into the ignition all of the dash lights work but as soon as I turn the key on, all of the lights turn off. All gauges work with the exception of the gas gauge which is stuck on full and the information system that has not worked since I bought the car. At night time I cannot see the mph or anything. Can you please help!
Sounds like your ignition switch going bad
