Has the wires on the back become loose.

bang your fist on top of it. failing that its time for a scrapyard instrument cluster.

A friend of mine had a 55sx (which is pretty much the same car as yours), we tried numerous instrument clusters which failed. It turnt out to be a broken peice of metal near the gearbox.

Ill ask my dad what the part acctually was later and report back.
