The bus bar/antenna lead terminals can be reattached by soldering, using a solder containing 3 percent silver and a rosin flux paste.

  1. Before soldering the bus bar/antenna lead terminal, repair area should be buffed with fine steel wool.
  2. Apply the past-type rosin flux in small quantities to the bus bar/antenna lead terminal repair area using a brush.
  3. Notice: Use only enough heat to melt the solder. Using excessive heat can damage the rear window defogger components or the rear window.

  4. The soldering iron tip should be coated with solder beforehand. Use only enough heat to melt the solder and only enough solder to ensure a complete repair.
