Stepper Motor Repair Stepper Motor Maintenance and Repair Services TigerTek provides nationwide stepper motor repair for all brands of motors. Stepper motors operate by converting a train of electronic pulses into defined mechanical movements. These instrument clusters had defective stepper motors that cause the speedometer intermittently to act sticky and hang up at certain speeds. I have a magnaturn 6south bend that has some issues with the stepper motor on the x axis.
I sent the thing to south bend to have it repaired before they went belly up. If we have a stepper motor fail it is maybe in 1000. Most later model GM vehicles had recalls with the stepper motors in the instrument clusters.
