I’ll let you know in a month or so when winter arrives in Buffalo. I did watch the video and if you notice they had the auto climate on set at only 68 degrees. That doesn’t seem nearly hot enough when it’s 9 degrees out.

Those two are either Drama Lamas, or they have the worst luck in every vehicle they seem to drive.

I have no issue nor do I think what they are experiencing is common.

Do a search. little plugs in the square vent holes. adjust to your taste

It was an issue for me on my JT as well as my JKU. But only during heavy wet snow storms. I love in NE Ohio

What I find that helps (not cures) is to turn on max window defroster and put your sun visors all the way down and far forward. It acts to push the warm air back down across windshield. Also I use RainX windshield fluid.

Regardless, in heavy snow storms I still get the build up.

Don't use Rain-X original water repellent (or equivalent type of product) before winter, it will cause moisture to bead up and freeze in beads on the edges of windshield that will not defrost and continually keep building up in time until you have to manually scrape off. Similar to the above video, but worse.

F winter!!!!!!!!!!!!!!!!!!!!!!!!!!

Took the Gladiator to the dealership to have them check out the defroster and they said it was a fault of Jeep in designing that way in all of their Wranglers. So consequently it's normal.

A lot of people seem to be using 1" plastic square tubing plugs and blocking off the 12-16 plugs in the middle of the dash. Posts say enough air gets around the plugs to still defrost the center of the windshield properly but forces enough air to the sides to get the full windshield.

In some of the posts they show the ventilation diagram from jeep and the defrost basically has two tubes that come up right in the middle of the defrost vent with no deflection to the sides so almost all of it just comes out the center.

@steffen707 looks to have participated in that thread and used plugs successfully on his Gladiator in Wisconsin winters.

You can buy the plugs on eBay.

Right you are! I bought these october 10th of last year, https://www.ebay.com/itm/24-Square-...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649

they work pretty well, occaisionally a few pop off and fly onto the floor. Like 2-4 of them per year.

At first I put 4 in a row then 1 empty spot. I've settled on all of them in the middle blocked, because even when all of them are plugged, some air gets passed and still defrosts the middle of the windshield.
