Not if there's no belt......

Agreed.

From what the OP posted, sounded like the owner got caught in a panic, deer in the headlights moment.

Does hitting the button on the dash turning the air on automatically kick it into a high idle?

I don't think it will because it requires a pressure sensor to engage.
