Terminal Repair

Tools Required:

• Rotunda Heat Gun 107-00300

1. Allow the rear window to warm up to room temperature for one half hour to an hour.

2. Clean the bus bar in the area to be repaired using fine steel wool (3/0 to 4/0 grade).

3. Restore the area where the bus bar terminal was originally attached by applying three coats of Rear Window Defroster Repair D8AZ-19562-AA (ESB-M4J58-A) or equivalent. Allow approximately 10 minutes drying time between coats.

4. Working as quickly as possible to avoid overheating the glass, tin the bus bar with solder in the area where the terminal will be reattached.

5. Using Rotunda Heat Gun 107-00300 or equivalent, preheat the glass in the solder area to 67°-83°C (120°-150°F) just prior to soldering the terminal on.

6. Position the terminal on the bus bar in the area that was tinned and hold it in place with an ice pick or screwdriver.

8. Start the vehicle. Turn the heated rear window on and leave it on for five minutes. Inspect the terminal and apply Rear Window Defroster Repair D8AZ-19562-AA (ESB-M4J58-A) or equivalent to the required area.
