I spilled water on my MacBook and though the keyboard was okay, the Airport card was no longer detected. I found your article on how to replace the airport card and disassembled my computer. I took out my card and tried drying it but to no avail.
I then ordered a card from your store and two days later repeated the experience and successfully repaired my computer with another Airport card.
You'd be surprised how much they pay Mac experts to do so little. Do it yourself.
