Right, and I have done some of the defroster plugs. Good point, I’ll have to go look to see if I have too much openness at the origin of the crack.When these JLs first came out this was common and seemed to often relate to defrost heat being focused there, then people came up with defroster vents or using scrabble tiles etc to even out defroster flow more evenly.
Not sure if that could be a factor here.
