A good place to start would be the compressor relay. The computer in your CR-V may disengage the compressor while passing for more power and it sounds like the relay may have stuck "off"
There are 3 black relays in the underhood fuse box that are all the same. You can swap them around and see if the compressor comes back on. The other 2 are for the cooling fans so I would not suggest driving around with a bad realy in the cooling fan spot.
