I've seen posts regarding steps that won't deploy; I have the opposite problem. After a long drive (more than an hour), when I come to a stop light, the motor home is still in Drive, my Kwikee auto step tries to extend but immediately retracts. If it's been a particularly long haul, it will do it multiple times.
Campingworld couldn't figure out what was wrong, though charged me $129 anyway.
My theory: Kwikee manual says that steps may operate erratically if the coach batteries are not fully charged. Note that the way my RV is wired, the coach batteries are not recharged by the engine alternator (not sure why, all my other rigs were wired differently).
I'm thinking while I'm driving, I have a draw on the coach batteries...fridge & my GPS perhaps?
Curious if anyone else has experienced this kind of thing with auto steps?
