you have an airbag that is cracked more than likely. If you do a search here you'll find quite a few of us have had issues with the comprssors and air bags.

I think your best is to switch out both airbags/ it's an easy job if you are somewhat mechanically enclined. You should be able to do both in under an hour easily.

or you can swap out to coil springs and will never have that issue again. you will need 2 coil springs and coil seats. will have to reflash teh computer when done and/or remove all wire/relay, etc for the compressor also.

...not sure on your vapor leak though.
