I have a 91 Geo Storm, The headlights go on by themself in the middle of the night or when it gets cold. The tail lights don't go on, just the headlights. I replaced the headlight switch and the computer and the relays but thay still go on. Anybody run across this before? I would think it's a problem Goe owners or mechanics have figured out before. CAN YOU HELP?    THANKS       Tom
