The rear defroster on my 77' 300D doesn't work because the wires on the side of the glass were cut. They were because the window needed a new seal. What is the best way to reconnect these wires so it will work again. It gets very cold in the morning and the window gets iced over and makes it hard to see. I tried to solder the two wires together but it still doesn't work. The light on the switch works so I believe it is getting power so I don't see the problem.
