The digital speedometer in your 1994 Caprice may not be working due to a faulty Vehicle Speed Sensor (VSS), which sends speed information to the speedometer. Additionally, issues with the wiring or connections between the VSS and the speedometer can cause malfunction. A blown fuse or problems with the instrument cluster itself could also be contributing factors. It's recommended to check these components for any signs of damage or failure.
There may be several reasons whey the digital speedometer might not work. The first is that the LED light may have burned out. The second is that the fuse may have gone out. It also might have a bad speedometer cable.
There are resistors on the back of the PCB that come loose. New resistors and some solder should fix the problem. what is the PCB and its location.

When the speedometer stops working and the ABS or traction disabled light comes on in a vehicle it indicates that the vehicle's ABS system is faulty. This could be indicative of a faulty wheel sensor or the ABS tracking system itself.
Just pray for it to come back on mine always does. Also stop slamming on the dashboard.
The check engine light only comes on for something that affects emissions

Yes. It is in the warning lights below the speedometer on the cluster. If the glow system isn't working the light will not come on.
Trans output speed sensor.
the 84 caprice classic does come with both right and left side mirrors
If your speedometer has stopped working just put the key in the off position and hold down the trip odometer button until you see some codes come on the odometer. That should reset your speedometer. I could not figure out which fuse was for the speedometer and some one told me about this and it worked right away.
