I was on a trip and at a campground when mine went out. I was able to get a mobil RV tech to come to me and he diagnosed the problem as the motor/gear box. I got in touch with Randy at Forrest River and they sent me a replacement. Had the mobil tech return and install the unit.
As Phil mentioned, I would look around your coach and make sure that they are not hidden in a closet somewhere. If they are not there, contact your dealer and tell him that you don't have the slide locks and that he should get them to you.
