Soldering Defroster Contact Tabs
In many cases the terminal tab will still be in the connector when you examine thevehicle. For Chevrolet Tahoe, Suburban, GMC Yukon, and Cadillac Escalade vehicles(with moveable glass), always replace the defroster tab (GM-P/N-25916031) and thedefroster electrical power connector (P/N-12034110). For all other vehicles, reconnectthe original defroster tab.
In most applications it is preferable to create a new solder connection to reattacha separated rear defroster tab. If you take note of the steps below, it is possibleto create a new solder joint that is equal to, or stronger than, the original. Thegeneric procedure below is not very time intensive, but does include minor preparationwork to create a good bonding surface. Be sure to follow each of the steps, as combinedthey will producethe strongest bond possible. Please consider the following before attempting the repair:Soldering introduces significant heat to the glass window of the vehicle. When performingthe re-connection of the tab, use only the heat required to do the job. Pre-heat thesoldering iron and have the solder in your other hand, ready to go, the moment youhave enough heat to melt the solder.If it is winter, bring the vehicle into the service garage and remove any snow fromthe back window area. Allow time for the glass to warm to the temperature inside thebuilding. 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 glassbreakage. ALWAYS wear safety glasses when performingthis repair!You MUST use a silver-bearing solder to make the connection. DO NOT attempt this repair with conventional tin/lead alloy solders. Silver bearing solder will adhere to the electrical buss bar, makinga strong and lasting repair.Protect surfaces under the area to be soldered. It is very easy to drip solder whenperforming this repair. Placing a shop towel under the soldering area is sufficientprotection.Soldering ProcedureIt is imperative to remove and replace the rear defroster electrical power connectorby crimping a new connector to the feed wire. The proper connector P/N 12034110 canbe found in the Packard Electrical Assortment, Tray 18, Position 5.Insert Delphi pick 12094430 to depress the locking tab on the terminal.Insert Delphi pick 12094429 to release the secondary lock tab.
Important:DO NOT re-use the existing defroster tab on new-style full-size utility vehicles with moveableglass.Connect the electrical connector to the defroster tab. Fully engage the connector.An improperly seated connector may cause excessive resistance and impede the properoperation of the defroster.
