Door ajar light
 

I'm new to this forum and enjoy my "new" '03 Dakota Quad sport, 3.9. My problem is hte other day, it was pretty cold out and had rained the night before. I was driving to work and about 10 minutes into the trip, I got a chime and my door ajar light come on. I reclosed the door and the light went out for about 1 minute. It kept on happening until I got to work and as the day warmed up it went away. I couldn't even see the switch on the door jamb or anywhere that I would expect the switch to be. Sooo... where is the switch and has anyone else experienced this problem.
