Heated Glass Element: Service and Repair

Rear Window Defogger Braided Lead Wire

Installation Procedure

1. Obtain a solder containing 3 percent silver and a rosin flux paste.
2. Remove the rear window defogger fuse.
3. Protect the interior of the vehicle from the repair material.
4. Buff the repair area with a fine steel wool in order to remove any oxide coating formed during window manufacturing.




5. Apply a paste-type rosin flux in small quantities to the wire lead and bus bar repair area using a brush.

Important: Use only enough heat to melt the solder. Use only enough solder to ensure a complete repair. Hold the iron tip in contact with the bus bar as short a time as possible.

6. Tin the bus bar and the braided wire:

1. Coat the soldering iron with the solder.
2. Draw the soldering iron tip across the fluxed area.
3. Thinly coat the bus bar and the braided wire with solder.

7. Solder the braided wire to the bus bar:

* Do not overheat the wire.
* Apply heat to the top of the lead wire braid.
* Hold the wire lead and the bus bar until the solder has solidified.
* Wipe away excess flux with a solvent.

8. Replace the rear window defogger fuse.
