Help Interior leak???

ok was on the beach all day today and i was driving home with no shoes on and i feel this drip on my right foot "gas pedal" so them in like w.t.f. then a drip every like 20 secs the whole way home....not hot not cold but chilled water...
any ideas on what this my be????
i didn not have a chance to go under and see whats up
and yes the ac was on as it was humid out....
if it is not one thing it is another.....

 

ac drain hose may be clogged

 

seems like a common problem as of late-- maybe someone could take the time and initiative to create a DIY sticky on this??

 

i would have never have know about it if i did not have any shoes on...so who knows how long it has be going on for......

 

well i went under there yesterday and it seems to be the ac lines are not insulated and it was condensation dripping off the lines as it was very humid out
hope this helps
