Thanks for you request
There is a evaporator drain tube attached to the rear unit housing, you should be able to see it inside the grille cover that you removed before, the evaporator housing is very close to the floor of the vehicle about an inch or so, the drain is at the left front corner of the housing, there is a rubber hose attached that exits through the floor so water can drain outside, it's possible that the hose just came off, if not then there is a chance that it is just plugged up with debris allowing water to collect and pool inside, in that case you can look underneath and you'll see the exit hole, carefully poke inside the opening with a thin piece of wood to dislodge the clog, if water drains out you're done. If the hose is still sticking out the bottom but disconnected just try to push it up to re connect to the evaporator drain connector. It may be necessary to remove that entire trim panel to get access to re connect the hose.
Not really, it's mostly held on with clips and a couple of screws, I'll give more details later if you have to remove it
Have a good evening.
Yes, there is supposed to be a grommet in the floor around the hose but I don't think that much water can come from outside through there. The condensation is normal, from what you're describing it's quite a bit of water that's entering. One other possibility is a drain tube for the sunroof, it has one drain tube on each corner, the sunroof seal is not watertight and some rain water will get in but it is supposed to drain out through the drains out the bottom, rthis problem would be related to either rain or through the car wash, considering your location I would lean towards a sun roof drain tube issue. You can check for this by opening the sunreoof then pour a little water into the right side of the opening drain channel making sure the water runs toward the rear then check to see if the water drains out the bottom or the inside of the car, if it's clogged it will usually cause the leak to be up higher at the headlinder.
Not a problem, try running some water from a hose over the back area, maybe have someone do this while you observe on the inside.
I will still respond to your replies even after you give me a rating, it's up to you.
