Get some electrically conductive epoxy, glue it yourself. I fixed mine that way, and it’s been good for about four years or so.

It's been a week since the new glass is in. I am trying to keep it from falloing off again.
BTW, tech in Jeep dealership said this time when it fell off, he would not be able to glue it.

I also found this. Obviously at the dealerships they do not read these.
It is a Stellantis document, I found it at NHTSA.GOV. I guess it is important enough they kee it. The doc is from 2023.
It covers 2018-2022 JL Wranglers.



PS. If I ever am to glue it myself, I will change the connector to a QC (Quick Disconnect) type. They can conduct currents upward of 20A with temp rise 10-30C.

I fixed mine after reading all the treads on here.

I ordered this button here:
https://www.amazon.com/dp/B075LP561G

Removed the old button and put this one on the wire.
Then with a solder pen i heated the button and put solder on it.
Then sanded the window contact with course paper.
then heated that connector put solder on that window connection
Then this part was a little tricky - I heated the solder on the window connection & then quickly heated the button & then the window connection solder so they were both liquid
Then pressed the connection button on the window connection using a needle nose plyers (because it was really hot).

First tried came loose, 2nd try held good and has held since.

There was also another post one here to used some clear cocking to hold the wire to the window.

That quick connector 68499001AA lets you extend the wire - good idea for next time for sure.

I soldered one of those 20+ years back in my Cherokee Laredo. I used a butane-fired portable soldering iron and wire solder. It was in the winter outside. So the soldering wasn't the best, but it held for a few years.

I suspect, it needs to be done

1) during the warmer period
2) it could be done with heatgun
3) It is better to use eutectic PbSn solder as pure tin is susceptible to the Tin Plague due to low temps and vibration (I nevert quantified it so do not know if the Jersey Winter temps are bad enough, even coupled with the vibration and intermittent heat/cold).
4) I also think that solder paste with some additional flux could be used under that connector

I guess, when in 3-1/2 years (or 55K miles) my extended warranty expires, and this contact falls off again, I might just try it.
