2001 Chrysler 300 Fog lights

I recently replaced the fog lights on my 300m. They worked for about 5 minutes and then both simply shut off. The ligt bulb are fine. I even installed the old ones again, but nothing. I looked at the fuse box and could'nt find a specific fuse for the fog lights. There is a spot for a fog light relay but it was empty, it seems like its not supposed to be used My question then is:

Where is the fog light fuse or relay on my 2001 300m? What else could cause for the lights to turn off?
