Hello!
While doing this process I accidentally broke the locking flap of the fan (step 46), and after turning on, the fan is not working. Apple diagnostics gives ppf004, ppf001, ppf003.
Is there a way to replace the locking flap?
Hi there.
There is a way to replace the locking flap, but it's rather hard. Here's a guide on how to do the procedure, and here's some extra info and possible alternatives. Let us know how it goes! Good luck!
Do you need to put the screw covers back on after replacing the fan or is it ok if you forgot to put them on ? Sorry for the basic question I just want to make sure .
Hello! While attempting to screw a 2mm T3 screw back after completing my repair, it snapped in half. The tip is stick inside the thread and the head fell out, which means the cable cover is loose (see steps 37 and 38). Is there any way I can remove this screw? The hole is so small I can't even get a thin-tipped tweezer in there. Also, once removed, where can I get a replacement screw from? Thank you.
