Steppers are fairly simple motors. It's 2 windings and they are energized one in one direction then the other then the first in the opposite direction then the other and so on. Check out the windings with an ohmmeter for continuity. This assumes the armature isn't stuck or the geartrain is working freely.
The speedo end at the trans is a simple pulse generator and the circuit generates the proper switchings for the stepper to run. The other part converts the pulses into current i.e. more pulses to more current.

Just an update guys. Changed my speed sensor and the interests circuit on the board in the cluster and no luck. Still only have my speedo... Does anyone know if they sell the stepper motors that are in this unit?

try getting it past 50mph and snap the trip reset a few times, one of mine was failing from trip sticking, and would recover doing that, had to be at speed to work, I don't touch the trip reset and I continues to work.

ill give it a shot. I spun everything by hand and it seemed ok. Is it possible to over tighten the screws on the stepper motor and have it bind that way? I cant find a stepper motor anywhere and whole clusters are $200+!
