: 40% – works if corrosion is mild. Fix #2: Reflow Solder Joints on the Cluster PCB (2 hours, $10 in materials) If cleaning fails, the solder joints are cracked. Open the instrument cluster casing (small clips or screws). Locate the large rectangular microcontroller (often an STMicroelectronics or Renesas chip). Use a magnifying glass to inspect the pins – you’ll see tiny dark rings around some pins. With a fine-tip soldering iron (350°C) and flux, reflow each pin of the microcontroller and the CAN transceiver (usually an MCP2551 or TJA1050). Add a small amount of fresh solder.
