Toyota Repair: Possible sunroof leaking on 04 Sienna, sunroof drain, drain tubes

Question
We are having some sort of drainage issue on our Sienna after a rain/carwash. We have a sunroof so I believe that is the culprit. This doesn't happen immediately but within a couple of hours the drivers side floor gets wet. I saw an earlier post that said drop the headliner and I was wondering how difficult that isto door should I leave it to the experts. They want to charge $200 to fix the issue without seeing it.

Answer
There are four sunroof drain tubes, two in fornt and two in the rear, most of the time it's the front that's causing the problem, the headliner doesn't have to be removed completely, to inspect the drain tube , drop down the headliner on the side of the suspected leak, remove the sunvisor and the overhead console and any assist handles in the roof, the "A" pllar on the iside of the windshield and the trim around the door opening, you should get it down enough to check to see if the drain tube is connected to the sunroof frame.
