Important: Do not overheat the terminal when resoldering.

    • Reattach the rear defogger bus bar lead terminals by soldering. Use a solder containing 3 percent silver and a rosin flux paste.
    • Before soldering the bus bar lead terminal, buff the repair area using fine steel wool.
    • Apply the paste-type rosin flux in small quantities to the bus bar lead terminal repair area using a brush.

       Notice: Use only enough heat to melt the solder. Using excessive heat can damage the rear window defogger components or the rear window.

    • Coat the soldering iron tip using solder prior to the repair procedure. Use only enough solder in order to ensure a complete repair.
