take the service line off the chambers first to make sure, or just listen to them to hear air coming through
the valve could be bad
I agree that the valve(dash knob) could be the source. Depending on how much it's leaking by. If it is a small amount I've had same issue when my trucks sit idle for a few months the seals in the valves can get dry and they will leak like OP. I spray WD 40 on them and cycle them several times and it stops leaking. Worth a shot- literally;)
