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

    Check your solenoid under the chassis probably burned out that's y it's not dumping volvo runs electrical solenoids with switches to dump suspension and lock diffs also for fans and air horns usually located right behind transmission depends on the year of the the truck

    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.
