Since the Neon was handed down to me, I've had trouble with the instrument panel not working. For the last three years I've been driving around with a ScanGauge II instead of gauges.
Today I finally got around to doing the fix described on the neons.org forum. I pulled the PC board, and found the problem right away.
Notice the cracked solder joints around most of the pins on the instrument panel power/data connectors.
The fix is easy. I re-flowed the solder on all of the pins, adding solder where necessary. All my gauges are back and should work fine for another 265,000 miles.
