Look at the connector that plugs into the airport card under the display clutch cover. If you can see two sideways "U" shapes you have the cable plugged in backwards and have most likely damaged your motherboard. In my experience plugging it in the wrong way once and powering on the unit will damage the motherboard causing the airport to stop working. The only fix I know is to replace the board. Sorry.
