The a/c evaporator is on the passenger side, did it rain before this happened or go through a car wash?
Thanks for the reply, if the water was clear and no rain or other water got on the car then the only thing that makes sense to me is that it came from the a/c evaporator housing meaning the drain tube to the outside may be clogged, however I have never seen a drain tube exit on the driver's side, it's always on the passenger side.
Under normal circumstances there is no reason for the floor to be wet after the repairs you mentioned and I don't see any correlation there.
Try to dry it out and keep an eye on it, maybe it happened while in the shop, we don't know what, they could have spilled water in it and didn't realize and didn't clean it out.
Sorry for delay, was out of town.
Possibly yes, from what I know so far there is no way water can get there unless it leaked in from the sunroof or windshield and the a/c evaporator core.
The evaporator itself actually doesn't leak, it's the water that accumulates due to the refrigeration process, there is a drain pipe at the bottom of the housing that exits through the firewall, during normal operation you should see some water exit out of the pipe, you can see the housing and the pipe where it goes through the firewall on the passenger side after you pull the carpet out.
My fault, I should have re read your earlier post, if there is water collected inside the housing it should exit when the hose is pulled off but sometimes there can be debris inside clogging the drain hole, if you suspect this poke something (coathanger) jus5t inside and see if it can be dislodged.
If there's anything clogging the drain it would be right there at the drain hole, it sounds like there is no problem with that. maybe it's best to dry everything out and keep checking or even better dry the floor and drive it without the carpet a couple of days, if any water should collect it would be very easy to locate.
You're welcome and good luck.
