since these components are on different circuits , I would be inclined to think that you may have a loose ground in the dash...unfortuneately I dont have a schematic handy for this older model so you may need to obtain one ... Try the public library to copy...and if thats no good you should certainly be able to find one online....Judging from your description I dont think you have a failed component because as I stated they are on 2 different circuits according to my sources...jeffrey590

It's the instrument guage cluster. I had to have the original rebuilt, everything now works.
