To reattach a detached rear defroster tab in most cases, it is advisable to make a fresh solder connection. It is feasible to make a new solder joint that is as strong as or stronger than the original if you follow the techniques outlined below. The process outlined below is not time-consuming, but it does require some modest prep work to ensure a solid bonding surface. Make sure you complete all of the steps because when they’re all done together, they’ll form the strongest relationship conceivable. Before attempting the repair, please consider the following factors: Soldering generates a lot of heat, which damages the vehicle’s glass windows. Use only the amount of heat required to re-connect the tab.
Pre-heat the soldering iron and have the solder in your other hand, ready to use once the solder has melted. If it’s winter, bring the car into the shop and clear the snow from the back window. Allow time for the glass to warm up to the internal temperature of the structure. The “hot spot” in the glass is created by soldering. Glass breakage can occur if the glass is heated too quickly or without allowing enough time for it to cool. When doing this repair, always wear safety glasses. To make the connection, you must use silver-bearing solder. Do not use standard tin/lead alloy solders to make this repair.
The electrical buss bar will be adhered to by silver containing solder, resulting in a sturdy and long-lasting repair. Use a soldering iron to protect the surfaces beneath the soldering iron. When doing this repair, it’s all too simple to drip solder. Protecting the soldering area with a shop towel is sufficient. The rear defroster electrical power connector must be removed and replaced with a new connector crimped to the feed wire. Insert the pick into the terminal to depress the locking tab. To unlock the secondary lock tab, insert the I pick. Attach the defroster tab to the electrical connector. Connector is fully engaged. Excessive resistance from a poorly seated connector can obstruct the defroster’s operation. To join the electrical connector tab and the defroster tab, use a small bead of solder.
Tape around the contact area of the glass if necessary, this is simple to perform and will allow you to prepare the contact surface securely without harming the glass or the black painted shading. To remove any remaining oil or dirt, wipe the freshly prepared contact surface with Kent Automotive.
