im helping my grand pa fix a 1997 monte carlo. the mph gauge dont work. so we bought all new vss and even tried a new gauge cluster with no change.but oddly we found that if you unplug the after market radio the cluster will work but as soon as you plug it back up its dead again. im clueless on this one.

its either the short or you may have to check the spedo sensor. or even a fuse can do that i had that happen before

Did you fix this yet? I have seen this before on the exact same car. There is a green with white stripe at the radio harness. It is probably grounded. The one I saw is that the dumdum (the owner) hooked it to a speaker wire so when the volume was turned up so did the MPH's on the dash. So find that wire and make sure it aint grounded somewhere on the radio or in the dash. Hope this helps.
