My original trackpad failed so I ordered a new one from iFixit. It responds normally to touch but won’t “click” when I’m trying to select something. I’ve adjusted the T5 screw up and down where it connects to create the “click” but to no avail. No idea what else to do and it’s driving me crazy.
Make sure you got the correct trackpad and the frame is not bent from a swelled battery. There are a few adjustments one needs to make when putting a trackpad back in the first is making sure there’s a slight clearance around the case and the trackpad. The easiest way is to place a few Post-It small note sheets around the sides as a spacer. Then tighten the screws marked in Orange marked here:
The next is the click switch its self often needs adjustment. The switch is marked in Red here:
It is adjusted by a setscrew maker in Green in the first image. Becareful as you can go to far allowing the setscrew to fall out. If the plat does not go down you’ll need to rotate out 1/2 a turn and check it thats better. If the plate depresses does flex then the setscrew needs to go in. Again turn 1/2 a rotation and test.
