I went to my dealer yesterday and spoke with them about this. They confirmed that the top wipe should go with the direction of the slide as ktmrfs stated. Seems it is common when a unit sits in the lot with the slide extended for display the wipe takes a set in that position. They use some self adhesive rubber molding they place lengthwise on the top of the slide that runs parallel with the wipe. As the slide goes out the wipe catches on the molding which gently starts the wipe in the right direction and friction with the slide does the rest. Closing the slide reverses the process. They gave me a piece about two foot long which I cut into three pieces which I spread out evenly to the top of the slide. It worked, but I'm going to get about three more feet. The farther the wipe was from the new molding the wipe the less it (the wipe) wanted to cooperate.
