Fog Light Switch problems of the 2003 Mercury Marauder

On the above date while leaving a place of business at approximately 10:15 pm I had no head lights. The headlight autolamp position nor the headlight manual position would turn the headlights on. I spent about 00:20 minutes trying to get the headlights to come on. I had to drive about 3 miles along a very dark secondary road in south carolina with only the fog lights working before the head lights eventually came on. The next evening more time was spent trying to get the headlights to come on, but nothing has worked. The headlights have not worked since. I have been trying to get the headlight autolamp position to turn on the headlights and I have been trying the headlight manual position to work but neither of the headlight positions is working on the car. I have a car that I can only drive during the day light hours. My research has lead me to believe that it is the 'lighting control module' that is malfunctioning.
