van loses speedometer after driving. volt meter also quits. new alternator and vss. problem persists.

If you were here in Bakersfield, California, I would have you bring your vehicle in for a diagnostic. As it is, you are more than likely not. Try and find a reputable Auto Repair shop and take your vehicle to them. There are many different things that can cause these problems, and without a proper diagnosis there is no one solution. The next easiest thing to do would be to install a known functioning instrument cluster and see if the problem persists at that point. A used unit should do the trick, but can lead to false negatives due to the nature of junkyard parts. Thank you for your time, and best of luck.
