Well I clicked that “picture” link and I don’t understand a word of it. LOL. All I can say is that the switch is not electrical. There are no wires going to it. There are just 4 tiny airlines going to it. It’s probably more of a valve than a switch. And it hisses when turned on. I’m wondering about the hissing. I can’t find anyone else who has one who can tell me if their switch hisses. If it’s not supposed to hiss then maybe I just have to change the switch to fix everything. It seems as though the switch/valve is not routing air to the step cover but just releasing air instead. Neither Google or YouTube have any info that I can find. But I’ll keep searching.
I have an air operated step cover in my American Coach and it DOES NOT leak air out. One time, several years ago, it did, but I tightened the air line connections on the "switch"/"valve" and it has been fine since. I don't think yours should be hissing either so I would tighten the connections on your.
Just as an aside, two things: You need a certain air pressure to do the position change. You should run your engine long enough to build air pressure. Should be at least 120PSI. Second would be that if you have hissing, you probably don't have sufficient pressure to do the position change, so tighten the fittings.
