Trailblazer help

How to fix the speedometer on a 2002 trailblazer 4.2. I've already replaced the speedometer and the speed sensor and it still doesn't work. Any clues on how to fix?

Stepper motor

The stepper motors go bad in must of the Trailblazers. Swapping them out usually works. Disassemble the cluster and there are 4 spots on the backside of the stepper motor. Unsolder and replace. Should be fine after
