Since there have been a few WS threads lately I thought I'd ask you opinions on what it is I'm seeing.

As of now I have not seen any water in the cab or even any signs of old water. (That doesn't mean much though.) A few weeks ago I found this on both port and starboard side of my WS.

If I were to venture a guess I'd say it's moisture or laminate separation but I know very little about this stuff. Can any of you identify what has happened?

(Orientation is vertical on both sides.)

 

Looks like it is separating. If I remember right there is a piece of laminate in between 2 pieces of glass, so one or both pieces of glass is separating from the laminate. You will need a new windshield.

 

Its the laminating film seperating from the windshield. very common with older safety glass.

 

I Found water in the channel under the trim tonight. :0/

 

Interior trim or exterior weatherstripping? May be time for a new windshield. I would have the dealer do it as they will typically replace the seam sealer that cause the windshield leaks in the first place.
