Here's the situation:
1. All three instruments (Speedometer, Odometer, and Trip Meter) go out at the same time
2. They work (or fail) together; this is sporadic and intermittent, without an obvious reason or pattern to the failure.
3. Cruise control works fine (and has been in use at times when these instruments fail).
4. The failure can last any length of time, from split seconds (as the speedometer needle "flutters") to minutes (the longest was about 28 minutes on a freeway).
5. The VSS has already been replaced, with no change in the erratic behavior.
How should I proceed for troubleshooting?
