Bad leveler valve?

If the left valve john suggested does not bear fruit, I'd look at all the valve rods and ball joint mounts and hit them with a stream of WD40. Maybe the cold,ice,road grime,etc. froze one of them. There is also a "bleeder valve" high on the road side upper C channel frame that could be dirty,etc. It is right behind the tag axle. Sometimes all it takes is for the outside temp to come above 50 degrees and air system issues magically fix themselves.

Pete,
Thanks for the suggestions. What is the purpose of that "bleeder valve" that you mentioned? I am not sure that I had heard of that one before, or understand why it would be up high on the frame channel.

Thanks!
