Air Step problem - will not completely extend without 'help'

[Terry Neal]

Roger,
Those are adjustable pressure valves to regulate the air flow in & out.
You can take them out & clean them & reinstall. Sounds like you have
some obstruction in one that is preventing the correct volume of air
flow and shut off or it has moved out of position.
