Remove ten Phillips screws securing the lower case to the MacBook Air:
-
Six 2.8 mm screws
-
Two 3.8 mm screws
-
Two 5.4 mm screws

-
Disconnect the port hatch ribbon cable from the logic board by pulling it straight up by its black pull tab.
-
Pull the audio out ribbon cable off the adhesive securing it to the upper case.
-
Use a spudger to pry the audio out ribbon cable connector board off the hard drive bracket.
I skipped the step (6c) of prying the audio out ribbon cable connector board off the hard drive bracket (& disconnecting it), since it doesn't come off real easily, and I didn't want to damage it. It only requires a little more care when removing the HD from it's bracket if you skip step 6c.

Disconnect the audio out cable from its socket on the port hatch ribbon cable.
Agreed, I encountered no issues when I skipped this on a Rev.B model.

Use a spudger to pry the hard drive cable connector up off the logic board.
Reversing step 8 is where I ran into trouble. The replacement fan I had was slightly thicker than the original and caused the ZIF cable to work its way out of the tenuous connection it had to the SSD, resulting in a "?" missing boot drive error upon startup. Took me three tries to get it right! The difficulty is to get the drive connector to the logic board to reach and seat without pulling the other end out of the drive.

Remove the four Phillips screws securing the hard drive assembly to the upper case:
-
Two 4.7 mm screws.
-
Two 3.9 mm screws.
-
Longer screws on top.
Two 3.9 mm Phillips screws.
Two 4.7 mm Phillips screws.
There is a cable glued to the diskframe that must be loosened with a spudger before you can remove the frame.

Use the tip of a spudger to pull the fan cable connector straight away from its connector on the logic board.

I have replaced several Logic boards at this point on the A1304 model, and realized that I did not need to remove the heatsink (Steps 14 through 17). You need to remove the screws around the fan, and disconnect the microphone cable (step 19). Of course if your replacement logic board doesn't include a heatsink, you need to take it off.

-
Lift the heat sink up off the logic board.
I removed the fan at this point as well. Disconnect the small connector from the fan to the logic board and lift out the fan. Good time to blow off the dust!

Remove the four 2.5 mm Phillips screws securing the fan to the heat sink assembly.
