Will the slides retract or is there no movement one way or the other now?? If they will not extend and will not retract, the problem will probably lie with the electric motor and/or the hydraulic pump that controls the slides. If the slides will retract, then I would use Art's suggestion of turning the other slides off (older models have the adjustment knobs in the battery compartment that can be used to isolate the main slide, newer models have control knobs located on the side of the rig). If it then extends fully, it would lend one to believe that it is a hydraulic fluid level problem. If it stops in the same place, there has to be a mechanical issue under the slide or I would think at floor level on the inside of the slide. I did kill the hydraulic/electric motor system and pump with an unbeknownst flip flop impeding the slide in the past (hazards of teenagers!!)
