I too have the older style Schwintek system in my 2012 Daybreak. To access the motors the outside column needs to be unfastened (in my case rivets) and pulled away from the outside wall. This is no trivial procedure. I've had four motor failures so I'm quite familiar with your problem. The newer models have a notch cut into the column on the inside which allows easy access to the motors. I therefore took an oscillating multi-tool with a carbide blade and cut my own notch in the column. The column is made of aluminum so it's not that tough to cut. The notch is 1 inch wide and 5.25 inches long.
