2004 Providence Windshield Leak

[jmusser15]

I have read multiple threads on here about windshield leaks. I currently have a windshield leak on the passenger side top of the windshield. From what I understand there is a gasket that holds the windshield to the frame and there is also a sealant applied, then there is also a trim molding that covers the windshield joint to the side of the motorhome. I have not been able to get a detail cross section to confirm the construction of this. If anyone can confirm or has a detail showing the assembly construction I would appreciate if you could share it. I am wondering if I can remove the trim and try to apply sealant in the area that I can see clearly leaking from inside the motorhome when it rains. I have already resealed the marker lights, cap to TPO seam, as well as applied fresh sealant to the TPO to side wall seams. I would like to attempt to correct the leak at the windshield as that is where I have narrowed down the leak to be. Any insight would be helpful. Thanks.

Buy a $20 tube of black windshield installation polyurthane. Clean the area where you suspect the leak, on mine it was the corners. Get some good masking tape to protect the parts where you don't want polyurethane. I used a large phillips screwdriver to hold the gasket open as I followed with the tube tip of polyurethane. When done applying the black goo, I carefully removed the masking tape. No more leaks. On an 18 yr old MH chances are the gaskets are dried, stretched, shrunk and generally in poor shape. The black polyurethane , when nicely applied solves it all. Yes it could be a problem for the next windshield installer, but that is his problem.
