one of the wires on my rear defroster unconnected itself. i was wondering if i could solder it back to the window and will it work?

three of my defrost wires become scratched and didn't do their job anymore. I grabbed a special pen from a local electronics shop that does the same thing as sodering, without the heat. Ran about $10 and made my job easier. Luckily that was before the window was tinted. Good luck

Most auto parts stores sell a repair kit for the defrosters wires. They are actually painted wires and it would not be easy to solder them and make it stick. The kit allows you to repaint them with the conductive material and repair the gap. It comes with instructions...

Are you talking about the tab on the window, not just one of the wires? Yes they can be resoldered, but you have to be very careful. The metal on the window is very thin and it easily burns, while the tab is fairly heavy and takes a lot of heat to get the solder on it. I tinned up the tab and then held it against the window with a blunt tip on a soldering iron. I burned the metal on the window a little, but it worked to reattach the connector. It has been working for over two years now with no problems. Be sure to clean everything before you try to do it. I went over the metal on the window and the tab with emery cloth to remove any oxidation so the solder would more easily bond.

yeah it is one of the tabs that came off. I'll try this weekend to reconnect the tab
