Digital dashes are stupid, unreliable, and look outdated IMO. The later style dashes are fine. Guess GM learned that the early style was to unreliable and expensive.

Since you have a 90, the best bet is to pull the dash display. If the search works, there is a very good write up on how to do it, plus it shows the connections that are a problem.
