Another Schwintec slide question! We just returned from a trip and slides had been working fine. Tried to run the bedroom slide out to unload trailer and one side is binding! It is not throwing a code of any kind like it did last issue I had but the left side is like it is in a bind and will only move about an inch and stops! I have kept moving it in and out and I have it out about 6 inches but can't get it all the way back in either! It was not out of sync because I had never failed to run the slide to full cycle since had trailer. It seems the motors are starting at the same time but the left one seems to bind up! I can't see anything that looks out of the ordinary, even tried to help it a little on that side but seems to not make a difference! Hope this is an easy fix, my patience is running thin on these Schwintec slides!
