rear window defogger

does anyone have any knowledge with regard to the soldering procedures on the rear window? the pigtails have become corroded and
disconnected. i,ve tried the normal procedures but cannot get the contacts hot enough to tin. does it require removing the contacts first?

Parts stores might have what you want too.

thank you for the info. this appears to be the solution i need but would also say that a good silver solder is more consistant with the oem design.
again thank you ted
