During the Rainy Season - I found out my '71 Duster had sprung a leak!

1 gallon of water through the wiper seals is a lot of water. Wonder how much was still left in the carpet. Wiper seals do leak but 1 gallon is a lot of water. What I have found over the years is the largest leaks are caused by the cowl drains clogged. Rust holes in the cowl behind the vent or heater box dams are very hard to see.

Fixing them is a job in itself . Removing the cowl is not necessary. This cowl was removed due to a leak and so much debri from mice it had to be cleaned.
