Wet Carpet

I just noticed that my passenger side front carpet is wet in my 1995 Contour and I believe that A/C condensation is backing up inside the car. I have seen this in the past on other cars and cleaning out the drain line corrected the problem. I can't find where the condensation drains on my car. Normally it's along the firewall somewhere, but I don't see it. If anyone knows where the drain is located on this model car, please respond.

Thanks,
Les
