Soldering Defroster Contact Tabs
In most applications it is preferable to create a new solder connection to reattach a separated rear defroster tab. If you take note of the steps below it is
possible to create a new solder joint that is equal too -- or stronger than the original. The generic procedure below is not very time intensive but does
include minor preparation work to create a good bonding surface. Be sure to follow each of the steps as combined they will produce the strongest bond
possible. Please consider the following before attempting the repair:
^
Soldering introduces significant heat to the glass window of the vehicle. When performing the re-connection of the tab use only the heat required to
do the job. Pre-Heat the soldering iron have the solder in your other hand ready to go the moment you have enough heat to melt the solder.
^
If it is winter; bring the vehicle into the service garage and remove any snow from the back window area. Allow time for the glass to warm to the
temperature inside the building. Soldering creates a "hot spot" in the glass. DO NOT solder on cold glass.
CAUTION:
Heating the glass excessively or repeatedly without time to cool, may result in glass breakage. ALWAYS wear safety glasses when performing this
repair!
^
You must use a Silver-Bearing Solder to make the connection. DO NOT attempt this repair with conventional Lead / Tin solders. Silver Bearing
Solder will adhere to the electrical buss bar making a strong and lasting repair.
^
Protect surfaces under the area to be soldered. It is very easy to drip solder when performing this repair. Just placing a shop towel under the soldering
area is sufficient protection.
Soldering Procedure

In many cases the terminal tab will still be in the connector when you examine the vehicle. Please reconnect the original defroster tab as
replacement tabs are not in stock as of today This bulletin will be reissued when replacement tabs are available.
