Help with Interrior Lights Automatic Timer

[wmaclaugh]

1995 T-Bird Lx 40th Aniversary Edition with keyless door entry. What relay controls the lights timer? What would cause them to stay on all the time? Sometimes the lights will come on and then off by themselves while driving. The door locks and unlocks when the lights go on and off. Any help would be appreciated.

My dad had a similar problem with his F-150. There is a secondary computer called a GEM modual that controls things like headlights, wipers, locks, vents, etc. If the GEM gets wet or is fryed for whatever reason it will cause your acessories to malfunction. I'm not sure if Thunderbirds have such a computer, but its worth a shot. They run about $150-$200 from Ford.
