The AC was NOT turned on, but the compressor turns. But I went the "hard" route, and disconnected the plug and it stopped!
There is also a switch behind the heat/ac actuator lever, designed to kick the a/c on when you move the lever to Defrost.
That switch can get stuck. The fix (at least in my case) was to clean and re-lube the switch. It's not the easiest thing to get to.
Regarding vac lines blowing off, I've also seen that happen on a vehicle with a malfunctioning PCV valve.
