Toyota Repair: 97 Celica water on passenger side floor, drain hoses, sunroof drain

Question
Hi,

I have a 97 Toyota Celica w/trunk and sunroof. Every time it rains I have a puddle of water on the front passenger side floor. I have seen water coming in at the front passenger side, where the door hinge is, at the bottom. I pulled up the carpet and the water is in the center and to the rear, under the passenger seat. The front (up near the glove box) is dry. The door seal is intact, but loose from door. Could it also be the sunroof drain hoses? I have had water drip out of my interior light too. Are there schematics somewhere that show the location of the hoses, etc? Any suggestions would be great!

Answer
Yes it's most likely a sunroof drain hose that has become disconnected or is clogged allowing water to collect and drain inside, there is a drain hose on each front corner, the headliner can be dropped down enough to check for disconnected hoses by removing the sun visors and the front dome light and the "A" pillar covers on each side of the windshield inside as well as any grab handles.
