AC won't run without the engine running.

The engine runs the AC

The A/C compressor itself is powered by a belt on a loop with the engine. The blower will work, but the A/C will not be cold. When the engine is running, the belt and pulle are moving, and thus the compressor is on, and youre getting cold A/C.
It's not dangerous to run it with the engine off, just pointless.

Only the Blower motor works with the car off, The AC Compressor WILL NOT work with the Engine off.
It's not dangerous, it just won't work.

It isn't dangerous, but it is ineffective. With the engine off, the compressor that circulates the refrigerant is not turning, so what little cool that was contained in the evaporator when the engine was turned off will dissipate very quickly.

we built a v dub with a 110 window unit intregrated into the back it would get to 50degree in about ten min,without the car running
as far as a traditional ac system it will only work if the compressor is spinning

The compressor clutch is protected by a low pressure sensor in the system, therefore no damage will occur if the A/C is left on while the key is on & engine not running.

No. The engine drives the AC compressor. ~

it wont run with the engine off ,the blower fan will run and cool it for maybe a minute or two,but that's about all you,ll get from it,good luck with it.

you can turn the fan on, but the compressor has to be running, before you can get any cold air.
