    I reasontly purchased a 2015 389 Peterbilt I noticed the airbag dump switch was on so I switched it back to auto leveling. But then I felt the airbags start deflating instead of airing up. I got out and went to the back of truck to see what was going on I noticed the dump air line was off and pinched off. So I tried putting it back on to see if it would work right but didn't. Airbags didn't air up even when I switched the switch back so I put it back the way it was crimped off with switch on dump . The airbags came up. What do I need to do?

    It sounds like your air lines are crossed, you need to find out which line is the supply line and make sure it is routed to the correct part on the leveling valve.
