I have a water leak that fills up the passenger side floor board pretty quickly. So i automatically assumed it was the windshield gasket and I installed a new gasket. Replacing the gasket did not stop the water leak. After further inspection i found that the leak is coming from the antenna. I drips onto the A/C fan motor then runs down into the passenger side floor board.

The gasket between the body and the antenna looks ok. Could the water be coming through the antenna shaft? Have any of you all seen this before?

Thanks!
John
