***SEE POST # 14 FOR PICS OF THE FIX*******

Just got back from a road trip to Houston (from Dallas) and when unloading the car last night I noticed the carpet behind the driver's seat (where the rear floor mat lays) was saturated. Real wet. Pulled back the carpet and put a fan in the car overnight (still damp this morning). Not rusty - had to be recent.

Hmmmm. I opened the sunroof and poured water into the rails on both sides (poured in the middle). Car took a pee onto the pavement from the rear wheel wells. Drains were not clogged. That seemed right.

I got nailed in a rain storm in Houston driving in on Friday, and overnight sitting in a parking lot. Maybe a door ajar? Window cracked? Water forced in somehow?

Initial look at the trunk - looked dry. I can't recall anything (like a water bottle) that could have leaked back there.

If water came in on the back edge of the sunroof - where does it go?

Can condensation from the A/C get back there? the front floors / floor mats are dry.

Any thoughts? Something to look for? I guess if it only does it once I'll rack it up to a door/window ajar?
