Hi! I did this as the bluetooth was not working on my macbook air (after water damage). Once I replaced it, instead of a "bluetooth not available" dialogue, Bluetooth options now do not appear in the System Preferences window, and in the system report, it just says "no information available".

Is this a connection issue, did I get the wrong card, or did the water damage actually destroy the antennae? Wifi works fine both before and after replacing the card.
