2003 Toyota Tundra Sun Roof Water Leak

Neighbor owns a 2003 toyota tundra sr5 with the extended cab.
2003 toyota tundra sun roof water leak. Water was leaking to the bottom of slider rubber track. Take a look for yourself. Nothing was obscuring the flow just the seal was failing to keep out the excess which flowed to the corners and down to the carpet. Can t find the cause.
Won t know for sure until the do a smoke test which is 175 and not. There is no evidence of any water seepage from the cab rear sliding window. The windshield itself and the seal around it doesn t leak. Waterproof sealant has been applied on the roof 2 rubber strips.
How to check sunroof drains in a car is a quick easy check anyone can do in their driveway. After a rain there is watering pooling in the rear corners of the cab. However there is water entering the cab from the passenger side behind the dash board.
