I had a previous 2010 Crossroads 5er. I had a similar problem and the end result was the slide motor had finally twisted completely off and was just making a popping noise which was the motor flopping around and around. Not sure if this is your problem or not. I had to manually bring my slide in with the crank tool. Welcome to the forum from NC.
