    I have a brand new leveling valve and brand new dump switch and my suspensions won't dump. Any suggestion?

    I have a 2006 vnl770. Would that have to do anything with my fifth wheel not moving either?

    Ok thanks. By any chance do you happen to have a picture of the solenoid you told me to check. I tried calling the dealer and they telling me Volvo doesn't use one.
