Water leak left rear passenger floor

[mtiger_dds]

We're finally getting rain in Ohio, and lots of it today.

I noticed a substantial puddle on the floor of the left rear passenger area this morning. It's a sunroof car, those drains appear to be functioning as they should. The door seals are all dry, it's dry underneath the rear seat cushion. I'm not sure where it's coming from.

Any ideas?

Rear windshield?

Rear windshield?

Possible. The rear shelf is dry. I didn't feel any moisture in the interior of C pillar or down between the seat and body. For the water that's on the floor, you'd think I'd find a stream coming from somewhere.

I'll take a second look, though.

Just had another monsoon pass through. I pulled the rear seat again, and this time there was water under the seat. The rear window gaskets/trim don't look too bad, but maybe its time to search for a new set.

have a helper run a hose on the roof/rear window/other areas while you're inside looking w/your flashlight?

Hose test results: the water is leaking from the rear of the sunroof drain channel. I know there are two drains located over the front seats, are there others towards the rear?

Yes they run to the "C" pillars if I remember correctly
