Pull the cluster out enough to probe the LB/R wire in the big connector WHILE the dash lights are on full bright, and see exactly what the voltage is. If it's below 11V, your "electrical" is NOT fine. If it's ~12V, then the 19-year-old blue filters over the bulbs are just getting foggy like most others. You can disassemble the cluster and remove them, but your cluster will look red/orange compared to what you're used to seeing. (That's what I did.) If you want to keep the blue look, just get some blue 194 bulbs from Wal-Mart or any parts store.

This site shows how to pull the cluster.
