I had the first hard frost on my windshield today and I am hoping someone can confirm your mod and then make it available. Outsides of the windshield took forever to melt. Last winter in a storm we had to keep the defrost on like a sauna and still had terrible buildup on the sides.
Well, I would have said it was all good on my 2019 JLUR but in the past weeks it has vanished. I don't really want to go through a tech support call to get it back, but I miss it.
