Thats the thing. I've replaced seals and put new foam in the box all doors are working and intact. but when I drive enough air moves through the box from the cowl to blow into the cabin and make it extremely uncomfortable in 90* weather. Today I made two special plugs that go into the inlet and outlet that block the water and still allow me to have the heater hoses in place. After I did that I let the car warm up and went for a ride and it was fine.
