- Buff the repair area with fine steel wool. This will remove the
oxide coating formed during window manufacture.
- Apply paste-type rosin flux in small quantities to the rear defogger
bus bar lead wire antenna and/or defogger terminal repair area using a brush.
- Coat the solder iron tip with solder. Use only enough heat to
melt the solder and only enough solder to ensure a complete repair.
- Apply solder to the feed bus bar or to the ground bus bar.
Draw the soldering iron tip across the fluxed area, thinly coating bus
bar with solder.
- Apply a small amount of flux to the underside of the rear defogger
bus bar lead wire antenna and/or defogger terminal.
| • | Align the spots with flux to the underside of the rear defogger
bus bar lead wire, antenna and/or defogger terminal. |
| • | Coat the tip of the soldering iron with solder. |
- Apply solder to the underside
of the rear defogger bus bar lead wire antenna and/or defogger terminal.
Draw the soldering iron tip across the fluxed area, thinly coating bus
bar with solder.
Draw the soldering iron across the fluxed spot, thinly coat the spot
with solder.
- Solder the spot on the braid against the spot on the feed bus
bar or ground bus bar.
| | Important: Do not overheat the terminal when resoldering the terminal to the bus
bar. The temperature of the soldering iron tip should be just enough to melt
the solder and allow the solder to run freely. The iron should be in contact
with the bus bar for as short a time as possible.
|
| • | Apply heat to the top of the rear defogger bus bar lead wire antenna
and/or defogger terminal, causing the solder spot to melt and fuse together. |
| • | Use pliers in order to hold the rear defogger bus bar lead wire,
the antenna and/or the defogger terminal. |
| • | Apply a constant force until the solder has solidified. |
- Wipe off the excess flux with solvent.
- Connect the electrical connector.
