Water dripping on front passengerfloor just in last few wks when using A/C.

I hope this is an easy fix for you, because it was for me. The condensate drain line coming from under the box in the floorboard is usually stopped up with dirt and algae etc. It may be hard to see at first look but you know the little line has to exit under this area to the outside. You may be able to use a wire, and then if you have more access try to get clorox mixture into the drain line. This should work!

If you didn't get out whatever is clogging the condensate drain line, then you might use a shop vac with a damp rag to seal the space around the drain line and suck out whatever is in the drain line. (I had to do this with my home AC drain line when insects got into the drain line to build a home out of dirt. I used a small shop vac which has a 1 1/4 inch diameter hose.)
