Driver Side Floor Board is Constantly Wet

My driver side floor board has been wet in my 2004 Mitsubishi Eclipse 2.4L. It started when i recharged my ac. I tried looking around the pedals since l've felt some water drip on my toes before but nothing seemed to be wet. I do have a sunroof but I don't know how to check if it's clogged or not. The cushion behind the pedals is wet if that helps. I don't know much about cars so I don't know how to test anything. Can anyone help?
