Leaking door or sunroof

I have to smile when the determination is blocked drains in the sunroof. Blocked with what? Show me the blockage.
I did check my car for such a thing. Use a wire they say. I used a very supple wire. Nothing. Ended up that the wire dislocated the vinyl tubing from the metal outlets that were in the sunroof. That was the easy fix. Found that there was water in the rear quarter panel in inches. Why cause the other end of the vinyl tube is suppose to go into a rubber outlet. They were not connected. I managed to reach my hand up from the rear compartment and fit the two together. The drivers side only.
The passenger side is more complicated because the fuel pipe takes up alot of room so I can't get my hand up to match the vinyl pipe and rubber grommet together.
Taped my sunroof closed for the winter. The water stays out.
This car will be like swiss cheese for leaking points from shrunken door seals to body parts that are not completely spot welded for their entire length, to a possibility of the windshield seal not fitting correctly. That was a multiple year problem which I find they haven't figured out yet. That gets the front carpets wet. I find silicone on visible seams in the wiper motor tray will take care of that problem there. For the rear, inspect the shock towers for rust and cracks and take off the side panels and look in there for rust. You will find something amiss.
