Have a friend with a 2000 DP and one LR slide. We were camping together and he had no problems with his slide.
When he got home he decided to do some lubing of his slide because at times it made noise when moving in or out.
He called me and said he could not move his slide not even a grown out of it.
Sound like a dead fuse possible to me.
Asked where his control for slide was????
The key operation over door was there, but where was the control.
Went into bedroom where fusing and controls for AC's and load center, 12V fusing but no obvious slide control.
Dropped the panel with everything mounted and on back of door a tag saying the slide control was behind the wiring, which is a mess.
Started to dig behind wiring and on floor of cabinet still no control.
Started to pull slack wiring and found a hole down into the outside wall and pulled up the lost control.
POWER GEAR SLIDE CONTROL
The fuse you see missing is a 25 amp slow blow and was blown because down in the hole along with this control is a bare #8 ground wire for inverter-converter.
The fuse blew on the fused side of fuse if it was grounded on battery side of fuse it may have caused some bigger problem with all the wiring in that hole and direct battery feed with ground wire fused to fuse holder on board.
The holder was pitted.
Why the control was never screwed to back board who new might have been coffee break time or Friday quiting time.
SO anyone with a slide 99 through 2001 I'd check and see if you have your control board mounted and not down the hole because eventually it may find that bare ground wire while traveling down the road.
You can see four holes to place at least two screws to mount the control and while your at it check the common ground buss with many wires and add another screw in that also.
