Good morning. I recall you stating you were somewhat of an expert on the slides. I have 1 2014 Voltage 3950. For four seasons, no issues with slides except for a motor short light on the living room slide, but it has always worked flawlessly. Late this season, the galley slide starting acting up. On trying to slide out, the rear of the slide would stop moving under it's own power. I have to push it out manually while holding the button and it will finally "catch" and go out. Retracting is exactly the opposite. The front will not come in on it's own unless I push the slide while holding the button until it "catches" and retracts all the way. Any suggestions? It is the Schwintek system
