I guess that I would start by disconnecting the linkage with the steps blocked so they can't extend. If the step motor works then you have a maintenance problem. The steps need to be lubed regularly.
If the motor does not operate, refer to the section of Kwikee Manual #888 for trouble shooting procedure.
If I remember correctly, your step motor will have the phenolic gear housing and I would bet it ain't a window lift motor but one that is proprietary to Kwikee. I forget the name of the mfg but they are in Oregon and are mentioned time and again in the Tech Issues. Check back more than 12 months.
Sorry tp answer so late, we are on the road and the WiFi has been sketchy at best and usually non existent. If you have fixed your problem or at least identified it, would you let us know along with the solution.
The previous post has the name for the motor supplier. Cheaper to deal direct than with Lippert if, they are still the owners.
