When you pull the cluster, clean the contacts and spray with cleaner (WD40 also will be ok) plug it back in and see if it makes any difference......just cleaning the contact will fix maybe 15%......You can also look for a used cluster...1990-1993 Riviers is the same and they made a lot more Riviera than Reatta making them easier to find.
