Got a truck in the shop right now where the rear suspension wont air up. Mechanic b4 me replaced the switch pack solenoid on the frame rail re pinned the plug on the body control module. I've cleaned the grounds on the firewall found a ground that wasnt connected on the starter, connected it still have the same issue. Air horn is not working and all the codes I'm getting is off the one plug on the body control module. I've ran a line straight from the air tank to the leveling valve which is new and it aired up fine. After I did that I reconnected it right and it aired up completely then dumped and wont air up agian

You would need a leveling valve that has a dump input port.

And the park brack has to be set -

At key on, in the run position, the body controller will energize the "A" solenoid which should be the one on the left when you are looking directly at it. Now, the blinking light doesn't not automatically mean the solenoid is bad. It just means the body controller is detecting a circuit problem of either and open or short circuit. If you do replace the solenoid, make sure you replace it with the right part number. Suspension dump solenoids have a slightly different resistance value of the other ones.
