This week my 94 SS instrument cluster has started having problems. The speedometer has been intermittent for a while now but this seem unrelated. Yesterday my speedometer, odometer, and turn signal indicators stopped working. The turn signals still work but not the indicators. All the fuses look good so I'm at a loss. Anyone experienced a similar problem?

So if I'm ready this right and the outside signals (bulbs) are working but your not seeing that on the cluster as well as other Cluster Issues, then it seems obvious the problem you are having is solely with the Cluster. At least based on what I'm reading in your description.

Could be a could of issues including the cluster itself. But I believe the Cluster is grounded at the Lower kick panel area and this area is known to cause problems. With all that is not working, it may be worth a shot to check the grounds there, remove them all clean the area and reattach.

It is also you have an issue with the Cluster itself. Loose or Cold Solder joints or maybe just something broken in the circuitry of the Cluster. There are repair services for this type of thing but they can be pricey. Some in that situation may just opt to replace the cluster with another. If interested and you find this to be the case, I do have a Used "Certified" cluster from a 96 9C1 car that I'm parting and the Odometer was at 151K. But maybe you'll find it was something as simple as a bad ground or solder joint.

Correct, the turn signals are working properly, just not displaying on the cluster. Everything on the cluster is working (seat belt warning light, air bag light, etc.) except for the middle blue display for the speedo, odo, and turn signal indicators. Would the others be working if the cluster isn't grounded properly? The speedometer and odometer have been intermittent for a while now.

OK, so it sounds like the LCD Portion of your cluster is what is completely out. I suspect this will give you a good idea of what to try to fix the issue as I suspect 1 or more of the pins aren't making good contact....

On this same site, he also has wiring schematics and depending on your skillset, you could use those to try and track down where the signal lose is.
