Air Grabber Fixing

Anyone have a dummies guide on how to fix an Air Grabber system?

what year make model , style ? and whats it doing or not doing

1970 Plymouth GTX. 440 with Six Pack added.

Air Grabber not working at all. Everything is there and would like to take it apart and put it back together without screwing it up. If it needs lubrication or servicing would like to do it according to specs. I am not a mechanic and need step by step instructions like a two year old.

90 percent of the time its a vacuum leak and mostly the switch , starts with the switch see if its holding vaccumm and go from there
there is also a little electric solenoid actuator but im pretty sure that just holds and keeps the door up once it works .

The electric solenoid bleeds off vacuum after the engine is shut down to close the air grabber.

I would suggest you start at the air grabber itself. Use a vacuum pump (or temporarily plum a vacuum line directly from the engine) and bypass everything under the dash. Hook the vacuum up to the actuator and see if it pulls the air grabber open. If it does, then start working your way backwards to find the problem. I agree that most likely you have a vacuum leak somewhere, but you could also have it hooked up wrong.

Not a great diagram, but this should help:
