As a newbie the first thing you need to do is try to learn the controls of your leveling system. I am not being a smart ass, but I am trying to get you to be able to define how your system is set up. As you may surmise by reading this thread the system controls are different depending not only on who the converter was, but how the cocah was equipped. What is reasonably constant is the underlying valve operation although some converters varied that as well.

To answer your question first tell us about your leveling system, or better yet attach photos of the leveling system controls.

Then it is probable that someone on this forum can walk you through the operation of the system, and from that you can report back and tell us what happens or does not happen, compared to what was expected to happen.

Condensation in the system is not unreasonable especially if the air system on the coach was poorly maintained, but apart from hydraulic lock it should not prevent the system from functioning.

Help us help you by posting pictures of your controls, or at the very least describing them.

You may find that on occasion we sometimes actually answer questions correctly.
