On my 2000 Magna, the drive mechanism in the bay under the drivers seat needed lubrication. It took some work by the tech to finally get the slide to operate properly. He first sprayed lubricant into the drive mechanism, operated the slide, came around to the entry door and pulled on the slide. Went back, sprayed again, then pulled again, etc. After several times of doing this, the slide would come out completely but have to be pushed back in. Again, the spray, pull, push and finally the slide began to work.
I'm single and never close the slide. I don't really know why I paid for the labor to get the slide to work except it is supposed to work and bothered me that it didn't.
