Rear defrost tab/connector

So my rear defroster seemed to have not been working the past couple days; finally took a look last night and looks like my passenger side tab/connector has detached from the glass. There seems to be a good amount of threads on this, and it seems RAMPANT on the JLs, but just wanted to start a new thread to get peoples' latest info/opinions.

How should I go about reattaching it? I am a terrible solderer, so I think first off I will try some of the "conductive epoxy" kits. The Frost Fighter one seems to have good results among various threads:

https://www.frostfighter.com/defrost...g-kit-2000.htm

The others (Permatex, Loctite, etc) seem to be not nearly as effective.

Thoughts/opinions/info anyone? If I end up soldering I'll definitely look to call in any of my buddies that are much better at it than me; don't want to end up with shattered glass LOL

Thanks all.

Dont solder. Safelite nor the dealer will repair these just for that reason. Permatex has good reviews and since we can have days in the mid 100's and lows in the single digits (I'm at 3,500' elevation) I went with this.

Used this a few weeks ago from Amazon. Used a C clamp to hold it in place a for a few hours. Works like a charm.

I’ve tried Permatex, but it didn’t work for me. I’ve followed instruction to the letter, but no bonding. Later on I’ve realized that the rubber “boot” surrounding the metal tab is not flushed with the tab, but extending slightly above tab's surface. That was enough to prevent proper binding. I guess I need either “thicker” glue or sanding down rubber boot to be flushed with tab surface and try Permatex again.

Mine just broke free a couple days ago. I'll be buying some permatex from O'Reilly's today.

Pry the tab out of the rubber boot with a pick tool or tiny screwdriver. That's how I did mine. Reattached last week and worked the 1 time I have needed to use it so far

Same thing happened to me a few days ago when I made the repair. Quite annoying.

Mine broke off a few years ago. Made several attempts at fixing it. No luck. Have gone without since. No big deal.

I noticed that mine was broken a few weeks ago. Wasn't really an issue until the other day when the temps got so cold that I have frost on my windows. Winter is closing in here in New England.

I will try to re-solder mine but want to wait until I get a warmer day. I am concerned about applying heat to the glass if it is too cold. If the weather doesn't cooperate, I may go over to a buddies house and use his heated garage. I don't have a garage.

If you use a pencil type soldering iron it should not get that hot and should keep the heat concentrated on the tab.

If that doesn't work then I may try one of the epoxy methods. Don't think that I want to go through the winter without a rear window defogger especially since I park outside.

I will update with photos after my attempt.

I don't know if soldering is a good idea. All of the research I've done has included strong cautions against soldering.

Problem with the epoxy methods is they generally need to be minimum about 10C/50F to have a chance to cure properly.

Hi I had this problem with this a few weeks ago while putting my hard top back on I popped the pass side defrost tab off the window. In the past I have tried to use regular electrical solder and the permatex epoxy. Never had luck with any of them. This time I used Solder-It silver bearing solder paste from home depot



https://www.homedepot.com/p/SOLDER-I...SP-7/300916097



This stuff worked amazing with low heat just make sure you don't over heat the glass when soldering the tab back on to the window. I took the tab out of the electrical connector sanded the old solder off the tab applied about the size of a pea to the tab and put it in a place on the side grid that the wire would reach to but was still silver in color (when my tab pulled off the silver part of the grid was pulled off with the tab). I held the tab to the window with a pick tool and held the hot soldering iron to the tab until I saw the solder flow around the tab, then I pulled the heat keeping the pick on the tab for a few seconds so the solder would cool enough so it would stick. The back side of the glass will be warm but shouldn't be extremely hot to the touch. Too much heat and you risk breaking the window. Let the whole thing cool for a few min and clip the wire back to the window. If you did it right the defroster is just as strong as the factory connection. I have had the defroster running a lot over the past few days and it is working perfectly. I would recommend doing this in a warm garage or on a warmer day so the glass isn't cold when you start the job, quick temp. changes can blow out a back window.



I have told my manager at Safelite about this stuff and now this is what we use at my shop to re-connect broken tabs that have broken off while the window was in transit to our shop.

I am thinking the problem with the epoxy stuff is when a clamp is applied the epoxy gets pushed out and does not leave enough for proper adhesion. I am thinking about removing the connector and placing a small thin Teflon washer around it as a mold for the epoxy. Then pop the Teflon washer off (I do not think the epoxy will stick to it). Then reconnect the wire.

Nice find. I think this is what I am going to try. With the jeep in my garage on a warmer day I might take a heat gun on low or a hair dryer on low and JUST WARM the glass a little prior to trying the repair. I could also let the jeep run with the heater on hi for a while to warm the glass, then drive it inot the garage to do the repair.

I tried that myself -- first thing actually -- and it was suboptimal in result. That said I don't think I did a very good job so I may try it again.

My Permatex fix is holding except there's one problem: the rear window defrost isn't actually working. Other than that, aces.

Thanks for all the comments everyone. Unfortunately the past week and a half has been pretty hectic and I haven't had the time to take a look at it yet.

I do think I'll start out with one of the epoxies, either the Permatex or maybe give the Frost Fighter a try. My neighbor also just finished building his new heated garage, so he'll probably let me use it. Either that or I can go to the hobby shop on base.

Went on a week long overlanding trip... and nwo the dogs popped off the other side. I'll go the same route as before. I did mine on a day that was in the 60's, maybe 70 in the direct sunlight. Used a clamp to hold it in place a few hours.
