front air bags

[Peggy & Ed McStay]

started the bird today and the front air bags will not come all the way
up.will rise about 1 inch and stop. rear bags come up just fine. iam
thinking it the leveling valve on the front axel. anyone have any ideas
as to what it might be. will look at the valve and see if needs to be
rebuilt and or cleaned. chime in with your ideas. thanks for any help
you can offer.
