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.

Buick Reatta Dash Problems Solving
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. Had a 1988 reatta in early 90s and really liked the car in spite of many problems with touch screen and dash and console lights. I have discovered a 1988 reatta for sale 30 miles from me that the owner says is immaculate with 100,000 miles. He claims it is loaded with a sun roof and only problem is inoperable radio ant. Reatta owners fell in love with Buick’s luxury two seater and they weren’t likely to want to abandon them any time soon. But, with the release of the overall production numbers (21,751), there were more questions than answers. Forrette contacted Buick Motor Division for assistance and was provided with a list of the original owners.
