Hi People,
The RPM verticle display on the instrument cluster is not working , but the digital (ie number display is ) Does anyone out there have an idea how to fix it or who can fix it?

From the sounds of this it is just a burned out light bulb. In your 88 I believe there is 4 bulbs. To get to these bulbs to change them you need to remove the cluster. Not to hard really. Also the bulbs you need are a little hard to find. In stead of me trying to explain this I will give you a link to a web site that has some very good information on the subject, including how to remove your cluster.
As a side note: I did change out the bulbs in my 88 last year. And I did it with out removing the cluster. I Used a small piece of rubber hose to go over the bulb and pulled it straight out of it's socket. Then did the same to replace it. This is not the recommended procedure, just saying.
If the fix is not simple and it seldom is. 'cause these digital electronical dashs are a huge POS.
