My 25DS is going in for the Bed Slide Problem...
We were 91 miles from home and got the bed slide halfway out. Would not move either way. Located the motor assembly after removing the panel in the cabinet over the bed. Make sure you have a stubby screwdriver with a square drive #2 bit. Had wife push button and motor turned, flexible shaft (looks like a speedometer cable, but about 3 inches), but no motion on the output shaft. That shaft has a pair of gears that "Bicycle Chains" connect to. They are very tight and have an adjustment on them. IF I followed the service manual and used the flexible shaft and a drill motor , it would not have worked because the gear box is "broken". The factory said to have the wife push the IN button and I should push on the slide to help the gearbox over a bad spot. Could be broken tooth in the gearbox. I did get it all the way back in and will have to go to the shop to change out the gearbox. Part is on order and should be able to fix this. Bed slides appear to be more of a problem than the front slide, from what I have read on the forum.
