Work has been killing me lately (oncall last 3 weeks). I finally pulled the Instrument cluster out. I found arepair tag indicating Jimmy's Radio in Phoenix made the repair onAugust 15th, 1994. I guess this instrument cluster was a problem back then too. I should have it in the mail in a couple days, so maybe I'll have it back for 4th of July[&:]

Pulling the instrument cluster was pretty easy.

Here are a few pictures of the Instrument Cluster. Easy to remove, take off the bezel, four screws attach the instrument cluster to the dash. 3 screws attaching the dash top, ease it out, pull back the metal connector clips, and pry the connectors out of the socket.

Take your time.You'll have it out, and on the bench, in 20 minutes. Remember to use a grounding strap when working around electronics, to reduce risk ofstatic shock damage.

Top board loosen (careful, connector on one corner need special tool to release pins. At this point, I'm sending it in for repair. [&:][:@]

This is the Vehicle Speed Sensor found on the rear portion of the 4+3 Doug Nash manualtransmission.

and this is the ECM Computer module. The chip is in side. release the two side clips outwards, the the chip pops up. Use static strap when handling chips and ECM.

I got news on the cluster today. No problems with the Cluster. He did replace all the blubs, and is sending it back. I'm buying a new VSS today[:@]. hopefully its not the harness[X(]

I'm still chasing ghost myself, replaced all the wiring in the steering column to get rid of a "blown fuse" problem in my tail light circuit..............didn't help, though my turn signal switch operates like new now and doesn't just dangle their anymore like it was.....so all wasn't lost. I have'nt even attemped chasing the "0" speedo, I was kinda waiting for you. Mine hasn't done that in a while (I haven't went for a real long ride though to test it lately)

Default resolution?

did the problem end up being the VSS? or did you find a different cause and fix it? came across this old thread while trying to figure out why my speedometer is having the same problem.

Welcome to the forum. You're posting in a 13-year-old thread. I doubt any of these people are still around. You should start a new thread of your own.
