Electricial Problem - Please Read :)

[Icey1174]

I know electrical problems are almost always unique.

My interior light worked fine for the past 4 years with the door switches. When I open the door and close it the light would stay on. I cleaned ALL the switches and I can find no reasonably, easily visible problems. Today I just noticed that the light will come on when the door is open. The light now goes off when the door is closed. As soon as I touch the key to the ignition cylinder the light comes back on. It is a little dimmer than when the door is open.

I assume there is some kind of short somewhere. Anyone have any ideas for what I should look at next?

Thanks for any help!
