1989 buick reatta problems

Hello I have a 1990 Buick reatta my dash only reads
00 error electrical problem and service engine soon
sometimes my speedometer and other gauges will
turn on for maybe 1 or 2 min but then stops working
again all lights on dash work with the test button
I’ve already replaced the ecm anyone know what
this might be?

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.

They were known for this and the best solution is to get a rebuild digital dash that may have a warranty, which should correct the problem. The issue was in the factory power supply to the digital dash. I had a 1990 Riviera that did the same thing, and I scrapped a 1992 Riv and resold a 1990 Reatta.
