minor question here: i put some of that copper paint/paste that causes cancer in california on the rear deimist in the 86 wagon - all the breaks seem to be mended but it still only works on a few upper lines and then only from the middle out and pretty weakly at that - anybody else done this repair had success and why does the defrost work like that? if it works at all on one line why would it not go all the way across?

not in big rush for help but curious...

thanks
andrew
