Air Step: won't stay in with sw turned "off"

[ED GARDELS]

Can someone explain how I can keep my steps retracted. I'm up on the
jacks and want to retract the steps so I can let the rig down off the
jacks.I have used aux comp to build up to 90 psi. The steps work with
opening and closing the door, at 90 psi, but with step sw at door "off"
the steps still work like in automatic. I dont want to let let rig down
on steps.
Last thing I did was at 90 psi, I turned sw "off" with steps retracted
closed door and steps still retracted.. I pulled the tank drain cables
on side of rig. When pressure got to a certain point while dumping, the
steps came out. Is this normal? All I want to do is put the rig down
off of the jacks.Any ideas??
thanks
