Hi,
My rear window defogger is not working the connector is broken off. I thought a simple resin could be used to connect it back while maintaining the current to keep defogger working, but guy at windshield centre told me, I need a new rear window cost €200. Car is '99 Almera.
If you can physically stick the connector to the glass with adhesive then you should be able to extend the electrical connection using a heated rear window repair kit, which you can buy in car accessory shops or on eBay such as [broken link removed].
