Digitsl dash help
Anyone know the fix for an 84-89 instrument cluster that intermitedly blanks out? When you slap the dash it comes back on. I know it's like dirty contacts, or a bad ground. I read what needs to be done a long time ago, but have forgotten it since I never had to do it.

Your plug for the cluster has come lose.
Remove the bezzel center of the car.
Behind it yoiu will find a plug and 3 or 4 of the connections in the printed circuet have come uncliped.
Just streighten the printed curcet and plug the connector back in.

Home repairs are easier than you'd think. I did mine inside two hours. Used a magnifying glas to inspect all the solder joints. Found a bunch of joints on the interconnect junction had gone bad and it only took ten minutes of soldering to get it right. I started to hit every joint on the power board until the magnifying glass appeared... Just goto the sites that everyone has mentioned here, read 'em through, and get to work.
I used the The 84-89 Digital Cluster Repair Guide Project by Bryan A. Thompson. It has some good illustrations and easy to understand text.
