My step quit working. It was in the extended position.
I reseated the relays in the R2 basement cabinet but that didn't resolve the problem.
I did some troubleshooting according to a manual available on the Lippert/Kwikee site.
I determined the motor was NFG and started looking at replacements via info from a thread here.
A 1996 or 1998 Ford Taurus driver side window motor was said to be a replacement.
I found these on Amazon and decided to replace all items instead of piece by piece. The motor had a different style plug compared to the current Controller and the motor had a different gear. However, the Gear Box had a removable gear which could have been reused from the original.

NOTE: The step did not extend or retract completely by just bolting everything up. I had to add 2 washers and a lock washer to get one of the bolts out of the way of the internal gears. I found this out by reading the reviews for the parts. Only one bolt needed the spacing. 

We shall see how long the motor lasts.
