I have a Chausson Suite Maxi 2011. The drop down bed is only coming down on one side, there doesn't seem to be anything snagging it i.e the spiral elect cable. The bed is now parked with a 30 degree angle on it and when operating the the buttons it all seems to be out of sync. when pushing the "up" button it comes down and vice versa and the only way to stop it going either way is the roof (up) and the seat base down or turning the power off. Can anyone advise please.?
