Interior light probelm - please help!

[JeffShap]

Hey guys, I just got a 1992 Thunderbird 3.8 V6 a few weeks ago as my first car.......Has quite a bit of miles on it (175K) but it runs like a dream, besides the engine mounts being shot.

But I have a few problems with it: for one, when I bought the car the interior lights weren't working. When I took her home and checked the fuses, I noticed that one of them was gone, and it was the interior lighting one. As soon as I popped that fuse in, the lights stayed on, and boy did it look nice. But I closed the door and waited for a good minute, and the lights stayed on. I tryed starting her and then turning her off, but nothing. The door switch isn't the problem because I tested that.

When I did test it, the lights would stay on for a bit while the door was closed, but would make a click noise and flash the lights off very quickly then get them back on.

So waht could it be? I scourged the internet and these forums and found no good answer. I read maybe resetting the computer would fix it, but I don't exactly know how to do that....any help would be greatly appreciated guys, thanks.
