I Have Almost Same Problem With My 88. My Odometer Started To Work But My Speedometer Now Goes And Comes When It Wants To. Good Luck!!! Let Me Know If You Find Someone Who Can Help.

look on ebay, type in DIGITAL DASH, if any come up for s-10s click on them, then e-mail one of those guys, they work on digital dashs and know all about them.
