Do the diagnostics work, is it just the speedo/tach/gauge module or everything ? 1990s are known to have issues.

Usually it's just the panel with the gauges on it. Radio and AC are separate modules.

Sounds to me like a bad connection either in the dash or in the module. With engine running if you shine a flashlight on the dash, can you see the gauges ?
