Since my Astro is still down, waiting for me to pull the intake manifold, I've purchased an '86 Volvo 740 Turbo wagon 2.3L to get me by in the interim.
One of the many things I would like to fix on this car is the speedo. All functions (speedo, odo, trip) are not working. I pulled the instrument cluster to find that there is no mechanical spinning cable attached to the rear of this speedo. It must get an electronic signal from somewhere instead.
Anyone run into this sort of problem in a similar vehicle? Do you have any suggestions on troubleshooting, places to start perhaps?
TIA
