Im hoping its just the motor thing that runs the needle on the speedo, but i was just wondering if anyone else had an idea what could cause it?

i don't think it is cable driven, it should be electronic and controlled thru the VSS. probably the cluster itself...

could also be a broken connection. Check the wires that run to the cluster I believe the VSS is dark green.

well the only extra cluster that i have is from a 88 with a digital dash, should i try it out?

 

the VSS should be good as the hud works 100% perfect.

Try soldering its circuit board.

GM electronics often comes to life after some soldering.

the digital dash mostly likely wouldn't be a direct swap, I don't even know if it would work at all.....plus the GP digital dashes are more unreliable then the analog ones...
