Leaking windows! 1968 Overlander

[birdie24]

How can you detect where a window is leaking? We have put new seals on all the windows, cleaned all the old sealants off and they still leak. Need help.

It's possible that the leak is coming from the seam around or above the window. Water will travel.

Something to consider. I had a window leak, was sure it was around the upper window frame, could'nt find or stop it. When I removed the inside skins I found it. A seam leak well above the window running down the inside of the outer skin and coming in through a upper corner in the window frame.

66-67 and 68 window hinges can leak.

Theat can be corrected by cleaning the exposed part of the hinges where the movement takes place, and injecting silicone sealer.

The window must then be opened and then closed every 10 minutes or so, until the excess silicone is force out.

That opening and closing process should be repeated until the silicone cures out.

That silicone process fills the gap between the 2 hinge halfs, which stops the water leak.

Thank you for the information. I really don't see a hinge? The windows seem to be leaking only in the very corners of every window which drips onto the floor. Would eyebrows help?

The eyebrows will make the trailer look tacky.

The hinge is at the very top of the glass, from one side of the glass, to the other side, and must be there or the window would not open.

Here is a picture of the hinge. On the second page(87)To install new glass #7 is a little like what Andy is talking about in post #4. Click on pics for larger image. Hope this helps.

We fought mystery leaks for quite a while, we then cleaned and sealed all seams with parbond sealant and it did the trick. Parbond will also flow inside the seam to create a good seal. Good luck I know how frustrating it can be.

Parbond does not remain flexible enough to use for sealing the windows. (glass to glass bar) Use good RTV silicone. This is the ONLY place you should use silicone on an Airstream trailer.

To find where the leak is, have someone outside with a hose and move from the bottom up slowly till you see water inside. Just use a flow not a wide spray. Mt 67 had water coming past the glass even with new seals. My simple fix is to leave the window just slightly open and the water passes right through.
