Slide out troubles

I have a GD Solitude model 320X, and the front slide will not retract or extend, it is about half way. It seems to pivot on the lower front slide, which does not move on it's own, but the rear moves a couple of inches in or out. is not a "lippert " slide, it has four r tracks on the sides of the slide. I checked the top and bottom to see if there were anyone obstruct ions, nothing! And while down there I pushed and t he slide moved I guess about 4 inches. I found the "two motor sychronous slide control and did the reset as instructed, (joke push the switch 6 times, then on the 7th time hold until light flashes, then at panel push retract butto). I have unplugged the batteriesm and then reconnected them. Thought it may be low battery, plugged into shore power. Still the front s not move, while the rear moves I am guessing until it goes to far and stops so that the slide does not get out of alignment. The fuse is good, which makes me wonder if there is another reset button, as the 5er has two rear slides that are massive, so that 15 amp DC fuse is not controling all three slides.

Question, has nanyone experianced this problem, and if so what was the fix?
