Resolder Connections: Using a fine-tip soldering iron, carefully reflow the solder on
any suspicious connections. Include a tiny dab of fresh solder if required to guarantee a solid electrical bond. Clean the Board: Wipe away any particles or old flux with isopropyl alcohol.
- Test Before Sealing: Test the card in the car before gluing the plastic real estate back together.
