There is no speedometer cable on that vehicle. The speedometer is driven electronically.
rpm and speedometer gauges not working 1995 Chevy silverado 2wd
If the speedometer is not working but the odometer is, I would suspect the dash cluster is at fault. If both speedometer and odometer are not working I would suspect the speed sensor on the transmission is at fault.
I have the same problem replaced speedometer clurstor got one out of wrecking took awhile to find one that worked ps you chang the sensor on the transimission . hopes this hepls
If the speedometer is not working it probably needs a new speedometer cable. If the speedometer is actually broken either take it to as speedometer repair shop or replace it.
See your local GM dealer for a reman swap.
i have a 91s10 4.3 auto and mine is not working either im going to change the vehicle speed sensor on trans and see if that works
It died of Chevy Envy
If both the speedometer and odometer stopped working it is probably the speed sensor in the transmission gone bad. If only the speedometer quit you may have to replace the dash cluster with a reconditioned unit.
Check the fuses.
There are several possibilities why the speedometer is not working. The VSS, vehicle speed sensor may have failed or become unplugged. The speedometer may have failed, or the ECM, engine control module, may have failed or there could also be wiring issues.
