2003 3575 slide-out problem

[FredG]

We have a 2004 3575 and have not had the problem, but I would check the hydraulic fluid level and make sure there are no leaks in the system, either at the pump or at the line connected to the hydraulic ram for the slide. Also, if you have the individual slide valve option, make sure all of the valves are fully in the correct position.

One potential thing you can try, if you have the slide valve selector, is to shut off the other two slides and see if that allows you to close the big slide.
