Hi Howard!

Sounds to me like there is a ground issue with the cluster. If you have changed the cluster already, and still have the same problems, it ain't the cluster itself, obviously. I would be looking at the ground circuits for the digital section of the cluster. Don't have a wiring diagram for that year here at home, but I can dig it up Monday once I'm back at the shop...if ya need/want. Once you determine the locations of the grounds, you can check to see if all are in good condition. Also, make sure the cluster connections are clean, and snug fitting. A little bit of corrosion on the terminals can cause intermittent issues like that.

Here's an abbreviated diagram of the ground distribution. The G200 ground should be on the driver side, end of the instrument panel, but might be down lower behind the kick panel. I'm still looking for a definitive location. I would most likely just run a redundant ground to the two terminals there at the IP connector. There's a LOT of other things grounded at that same spot....some might be affected by it, some may not. Best to clean it really well once you find it. Take the screw/bolt out, use some sandpaper/emory cloth on both the metal on the birdcage, and the eyelet.

Otay....I loaded the two instrument cluster diagrams onto my website...it'll be easier to see them. Here's the quick links to them. Just click on either of them to enlarge. Hope this helps.
