08 Rear air suspension won't inflate

I was driving on Sunday and with a matter of minutes the rear air suspension wen't from totally fine to flat, sitting on the bump stops on both sides. I can hear the compressor running but it will not inflate at all. I know it's common for the airbags to develop slow leaks and leak down over extended periods of time, but I haven't heard of this particular kind of quick failure where it won't pump up at all. I also usually hear of one side or the other falling, but will a leak on one side allow the other to deflate? I guess there's a major leak somewhere in the system. Airbag (or bags) is still my first guess, just curious if anyone has had similar experience. Any thoughts?

Rear driver airbag had a one inch split. By letting the pump run for a minute I could see the passenger side trying to inflate so I started with driver side when looking for the problem. Changed both bags in less than an hour and it’s fine again.
