Speedo only works sometimes. Replace it?

[neverrain]

Hey all,

I have been "accepting" of a problem with my speedometer that doesn't really bug me, but I'm to the point where I want to correct it.

My speedometer only works about 50% of the time. Sometimes it works perfectly, sometimes it sits at zero, sometimes it just does whatever it wants and bounces all over the gauge.

Is this something that can be fixed or would it be easier just to replace the cluster? I plan to swap out my dash in the near future (cracked dash ftw) and if I need to simply replace it I would like to do it then.

Anyone else have this issue before?
