- Obtain a solder containing 3 percent silver and a rosin flux paste.
- Remove the rear window defogger fuse.
- Protect the interior of the vehicle from the repair material.
- Buff the repair area with a fine steel wool in order to remove
any oxide coating formed during window manufacturing.
- 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.
- Tin the bus bar and the braided wire:
| 6.1. | Coat the soldering iron with the solder. |
| 6.2. | Draw the soldering iron tip across the fluxed area. |
| 6.3. | Thinly coat the bus bar and the braided wire with solder. |
- 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. |
- Replace the rear window defogger fuse.
