I’d be grateful if anybody could advise where the wiring for the electric window heating attaches to the window, please. I have a 1999 4/4 4 seater and in the rain water drips from the bottom of the centre of the dashboard. Immediately above it on the outside of the window is some blue wiring tucked into the rubber seal but which breaks the bottom of the seal with the bodywork. Logic suggests that this may be the source of the leak. I don’t know whether this is factory fitted wiring or a later edition to power something that’s no longer fitted.
