I've been struggling with problem since I had my 18 JL. I've had a bunch of snowstorme so far where I literally had to pull over and scrape the ice off the corners of my windshield becuase I couldent see. I'm glad to see this but sadly they are out of stock right now.Saw this on the JL forum, ordered the plugs from Amazon.
These would probably work... best way would be to measure and get the appropriate size to be sure though. They're just universal square tube end caps so I'm sure even Home Depot or Lowes would have them.looks like they are now unavailable.
before you do that, put all of the plugs in the middle of the defrost "bar". What i found is enough air still escapes past the plugs to defrost the center, and pushes extra air to the left and right.I bought and installed these a few days ago. So far, I can’t find the right amount of plugs in the center area to even out the airflow to the edges. Also, I’ve had a few plugs come loose and pop free.
I think I might try drilling 1/8” holes in about 20 plugs and cover the whole center section.
couple things, the flash makes my dash look super dirty.before you do that, put all of the plugs in the middle of the defrost "bar". What i found is enough air still escapes past the plugs to defrost the center, and pushes extra air to the left and right.
i first tried spacing every 5 or so holes, found EVERY HOLE was the best solution.
yeah i think it blasts it on defrost, open the passenger door, it'll keep blasting, then when you open the drivers door it'll change to whatever you last had it on, (i think that's what happens anyways).And this...windshield cracked from defroster heating in the middle only. I installed the plugs afterwards. Have another crack from a rock, so may wait till warmer weather to replace. It was not all that cold that morning and the JT was garaged. When auto starting, I think the heat comes out the defrost and changes once you open the door. This is what I see anyway.
