What is wrong with your 1995 Chevy 4x4 silverado when the tachometer and speedometer quit working as well as the shift indicator light?

There is a problem in the cluster. I would obtain a good used gauge cluster from a salvage yard , they are easy to replace. The only tools you need are a Phillips screwdriver, and a 7mm socket and ratchet. Once the dash plastic is off the unit just plugs in.

But of course, check your fuses first right?
