I believe that you have a "MCD' shade and have the control switch located on the dash. We have the same shade and had a problem with the memory not holding. Fussed with it for months and finally gave up and, after calling MCD, bought a new motor/memory unit and had it installed at the dealer while the rig was there for another problem. Have not had any problems at all since the change. If your rig is still under warranty it should be covered.
