Was having deep water in floor board every time it rained , all dry around sun roof but discovered drain tube on driver side for sun roof was stopped up below dash and draining into floor board , hope this helps with others with same problem , shortbus

First question I ask when a Bonneville owner says his car is leaking, is "do you have a sunroof". That stupid slip fit between the upper and lower front drain tubes, in an area that is absolutely not accessible, is a leak waiting to happen.

Good job and thank for sharing.
