Driving along, hear swishing sound coming from the backseat-put my hand behind the passenger seat and holy hell, there was gallons of water on my floor. Shop vac'ed it all up, and it happened again and again and again. I think it happens when my A/C is on and running-any ideas what it could be-car goes into Acura on Friday for a check

 

I think this might be it:

Check NiteRaven's posts, particularly post no. 10 in that thread.

 

thats exactly what my dad thought was going on-the A/C wasnt draining properly. The car goes in on Friday, which is the earliest I can do it. They already arranged for a loaner car, saying it might take awhile to fix, just like the other kid.
