Habitation Step

The automactic habititation step on my broadway comes out when the vehicle is unlocked but will not return either by the button inside or when i lock the vehicle. i can push it back manually.
Any ideas on the cause and a possible solution would be appreciated.

Yyou can push it back manually but have to lift the outer edge a little to enable this. It happened to me several years ago, luckily on the way to Willersey where it was fixed.
The problem was to do with a small button type switch that you can see when the step is out. It simply needs a clean and a bit of silicone grease. No problems since.

Thanks Ron
If the east winds not blowing at the weekend i will have go at fixng it
