Sounds like you need to replace the tractor air ride leveling valve with a new one not rebuilt before the next time you dump the air out and it will not air up ever again!

Replace the leveling valve or unbolt it and move it manually

What kind of truck is it?
My 379 has a leveling valve and a pilot valve. I replaced both, the leveling valve was pretty trashed and I replaced it, The pilot valve was the real problem in the air bags not inflating. When you dump your air bags this is part of that system. One days it worked great, next day no air.
Leveling valve cost about $70-80
Pilot valve is $30-$40
Easy replacement yourself, just make sure new leveling valve is adjusted the same as old one.
Peterbilt wanted almost $400 for leveling valve... truck pro $79... really hard to find stuff not made In China now. Peterbilt parts
had no idea what the pilot valve was...
Pilot valve in red, Leveling valve blue circle. Your truck may not have a pilot valve.

He PM me, here is my response for everyone else;
If the suspension dump switch is flashing, there is an error detected in the system. If not, then check the valve and leveling rod to make sure it is attached properly, not broken off or detached at the spring mount. After that, it is basic air checks to see if the valve is getting pressure from the truck and passing it on to the air bags.black_dog106 and 062 Thank this.
