Bad cluster/speedo?

My grandmothers 93 speedo don't work so replaced the sensor on the trans, still no worky. Is there a part on the cluster that can be repaired?

Does the odometer still work? The speedo and odometer work off the same signal from the VSS. If the odometer works, then the signal is getting to the gauge cluster and yes, the speedometer can be replaced. There might be issues with corrosion on the printed circuit board in the gauge cluster.

You need to check if the VSS is actually generating a signal and if it is getting to the gauge cluster. As the ring gear in the differential rotates, the VSS generates an alternating 5 volt signal that operates the speedometer and odometer. When I had problems with my wagon, I pulled the dash bezel (the black part), jacked up the left front wheel, then accessed the pins in the electrical connector for the cluster to verify the signal (ignition "on").

If just trying to verify the VSS, there might be an easier place to break into the wiring harness under the hood - I don't have my manual handy while typing this.

Do you have a wiring diagram?

I don't have a wiring diagram, have a Haynes on order. I'll start testing for the VSS signal
