I’ll give this a shot Tom, I’m just struggling to accept that all trace wires are open.

This was my adventure with soldering them back on. https://www.early911sregistry.org/fo...is-cable/page3
You should have an easier time. That said, its unlikely the horizontal wires will be functional after so many decades of oxidation.

when the 1st line opens all of the current goes through the balance of operating lines. as each line opens, more & more current is flowing through the rest.
Ravi,
Oh wow, identical to what i went through. Started at the switch and worked my way back to find these two wires. I have everything working accept the heat. Lol. Thanks for sharing. So what’s the end result, leave it alone? Buy a new back window? Any idea what they sell for? I might just button it up and revisit this “later”
So it’s a domino effect to burn them all?
They do sell repair window grid products that work well on other models of cars, https://www.ebay.com/itm/EASTUP-Rear...kAAOSwYwZcRZZk
I was able to buy a NOS wiring harness here not too long ago, so my car is complete, even though the defroster is the one item that doesn't function after all those contortions. Sierra Madre does sell a properly tinted repro replacement window with defrost wires for my S. It's not crazy expensive, but my rear glass is original, so right now I'm in the "leave it as is" camp. Switch, relays everything work and I'll think about it some other time. So far have had no need for it and I drove well into the fall, but almost never in the rain. I invariably just leave the rear quarter windows open.
So after doing a deep dive on the this-here’s why most of them done work.
1) not laminated between panes
2) oxidation, Brittle, chipped = open contacts
Here’s a close up of the trace wires.
Going with an after market might be the way to go, specially if they’re laminated between panes.
P.S. just realized, removing the tint with soap and a razor wasn’t helping either. Lol
I fixed mine by buying a new rear window, don’t think I have ever used it, but it looks good.
