I have read about all of the possible causes for water leaks in my 04 xc90 t6. I do have water somewhere in my car and I can hear it sloshing when I come to a quik stop, but I can't figure out where exactly it is and how to get it out.
It sounds like it is under the driver side floor or close by. And it sounds like a lot of water. I looked under the car and found some rubber plugs but when I pulled them out it was dry inside. also after checking the sunroof tubes and finding them ok, I don't know where else to look for leaks. My carpet is not wet but after a drive or overnight the inside of the windshield is all fogged up. I really need to get this figured ou because I'm afraid that the car will rust badly from the inside.
Thanks for any input

I would check the drain for the a/c.

 

I agree.

And get the carpets out of there so they can air dry. You may have to remove the rear carpet too.

 

My carpets aren't wet, I can just hear water sloshing in the car. How do I check the a/c drain?
Thanks, Jim

 

They are wet underneath. There is quite a bit of foam padding under the carpet you see.

The drain goes from the climate unit to the firewall near the accelerator pedal on the XC90 if I remember correctly.

 

Thanks for the reply, I'll check it out

It generally happens when the sunroof drains get clogged they back up into a spot underneath the floor mats.. Once you car hear it sloshing.. Quite a bit of water is under there. Get it fixed pdq before you start having electrical problems. Also do a search for sunroof problems/leaks on this board.
