2001 Z 24 Cavalier Turns off when i turn off a/c in park

That’s pretty much it. I’m in park with a/c on. I reach over to turn a/c off then car turns off.



Very strange.



And sometimes I turn car on and turn on a/c only for car to turn off.



The car turns off everytime i’m in park and turn the a/c off.



Please someone help.
