MVS Forums member VFLXC90 had a wet carpet disaster in his XC90. This is how he tracked it down and fixed it.
The XC 90 had wet carpet this summer. I youtubed the sunroof drain fix. The drains were clear?
The carpet was soaked. When I ran the A/C the condensation wasn’t dripping out under the XC. The drain line was plugged. That was the easy fix. Drying out the carper was the hard part.
If you look in the area of the gas pedal to the right of it. You can see a small black flex able hose behind the center console trim pane. That’s the hose you want to pull out and stick a close hanger through to clean out the clog. The trim panel on the side of the console will pull off. Just grab it in a corner and give it a hard pull. Then work it from left to right pulling. It will come off. Just pull it.
