Rear window defrost/repair question

[Chris Pomares]

I had the rear window on a 69 going to media blast removed. The defrost wires weren't connected and we found the prongs missing. Does someone sell replacements and can they be soldered back on?

Does anyone sell the prongs that are missing on the rear glass? Has anyone had success soldering them back on?
I looked at a 70/71 rear window and it had 3 connections per side. This car is a 69 and has one continuous piece on each side.

Hi Chris

You might check the heating elements for continuity before you have the tabs soldered back on. I found that almost all of the elements on most of the early single windows I checked were damaged and did not conduct. No easy fix for that as best I know.

Good idea thanks.

Also when checking for continuity use a piece of tin foil as the sharp points on the meter tester will damage the fragile horizontal lines . They can be easily broken and damaged .
There is a company that sells repair liquid with high silver content.
Lines can be masked and painted with their material.
I bought some but have not tried it yet.
You might need to buy another cheap window to get the tabs.
Obviously the 3 contacts is for a 2 stage defroster and the 2 contacts is for the single stage.
This will also need to pair up with the relay ...either single or 2 stage.

Also took a good look at your horizontal defrost lines, they look pretty broken and deteriorated .
Don’t think you will get good conductivity.
Let us know and hope for the best.

Don't bother. All you will do is waste a bunch of time and possibly a small amount of money. I've got 50 of those things and I'll bet not one of them works. The only good thing about that glass it that it is not a later "2 stage" heated glass that would be twice the PITA to try and repair.

If you really want to repair with new tabs check out Planned Products in Boulder CO.
They show a defroster repairs . There is a photo showing the tabs .
Also other defrost repair items .

I had a connector tab fall off the rear window of my Boxster (2003 was the first year with a glass rear window) and I believe I fixed it with Permatex® Rear Window Defogger Electrically Conductive Tab Adhesive from a Friendly Local Auto Parts Store.

It wasn't all that difficult and the rear defrost works (although a couple strips may not be heating up). If your windows are out of the car it should be easy (compared to working under a Porsche rear window).

interesting.

i will be installing my 1969 rear window next month.
i should see what condition my rear window defrost is.
