I recently bought a 1999 Winnebago Adventurer. I have noticed that the slide creeps out slightly when it sits. I tried to expand the slide and it will not do anything. I took it to my small local dealer and he couldn't find the motor nor the fuse box that goes to the slide. Of course I have every book but the one for the slideout. My dealer automatically thought it was the motor. Any suggestions would be greatly appreciated.
