Post subject:  Repairing electric rear defroster grid

My 83 Dodge van has the electric rear defroster grid on the back window. It doesn't work right now because one of the terminals has ripped away from the glass. In the past on other vehicles, I have had middling success repairing these terminals used those bottles of rust-colored "electric grid repair liquid" like you can order from JC Whitney.

Is there a better way/better product?

There is a paint on substance that you can use to: 1 - repair individual grid lines, and 2 - re-attach broken off connectors. I used some when I was in college.

I will see if I can find said magic substance.

Does it come in a dinky little bottle with the paintbrush attached tot eh cap? If so, I am pretty sure that is what I have used in the past too. I was just wondering if anyone knew of any other way.

I'm trying to remember where I saw a "band-aid" type repair for that recently. I believe it was a sticker with a small wire embedded across it (ish). NAPA doesn't show it online, but I periodically spend a bit of time at the counter there, so perhaps that's where it was?

I may be wrong, but I think it used to be a Mopar part number for that bottle, maybe it still is?

I am going to try some conductive epoxy. I'm checking the local Home Depot tomorrow to see if they stock any.

Reed, If you have a later model Factory Service manual, for any Mopar, I'm pretty sure it lists a procedure for repairing the grid. All my FSM are too old.

I have the correct 1983 FSM for the van, but I didn't think to look there. D'OH! I'll look it up and see what it says. However, at this point I don't need to repair the grid, I need to reattach the terminal on the side of the grid.

If the glass is still good (which it is in my case), you might want to try to completely remove the defrost grid and apply a brand new one. A friend of mine who worked in auto glass for many years recommended I try one of these kits for my cars. I haven't yet, so I can't say yay or nay on whether they work, but it's an option to investigate. I have to fix the lift gate on my truck anyway, so the glass will be coming out and while it's out I'll redo the defroster.

Thanks. I actually bought one of those for my brother's van, but I haven't installed it yet.

You could try a "trace pen" from an electronics store. It is a gel pen that has a conductive paint in it. I have repaired broken traces on circuit boards so it should work on glass. They are about 6 bucks.

I've used those after-market grid kits, the kind you buy to install on a window that previously never had the electric defrost grid option. I used to buy them from J.C. Whitney, but they no longer carry the kits. The last two I bought on line. I don't think I'll buy them any more. Even being VERY careful to follow instructions, the grid wires and side bars tend to pull away from the glass within a few months. Generally, the longest useful life I've gotten from them is about 3 years. They do work, but not for long. I think the adhesives that they were manufactured with are old school , or the kits are old (NOS) as is the adhesive. I'm going back to factory blowers on our cars. That's my 2 cents worth.
