Gamecube C-Stick up and down doesn't work.

[ChiroTheSkunk]

Recently bought a T1 Gamecube spice orange controller, over time the C-stick right and left directions started to drift, so i opened it and took out and reinserted the Potentiometers for cleaning.

After this, Left and Right works perfectly fine, however up and down doesn't even work now.


I think its because the upper part of the potentiometer case snapped in half a bit when i tried to re-insert it to the Stick box, but i didn't give it importance since it still was held together well, until i realized that maybe the crack reached the brown part in the case and i then considered that could be the issue.

is there a way i can fix this?

stuff i tried:
-Swap potentiometers
-Clean the potentiometers and stick box with contact cleaner and a brush
-Re-insert and apply pressure on the potentiometer case
-Hold X, Y and Start to reset the controller

Also, as an additional issue, the rumble motor doesn't work either. When the controller arrived the rumble was already dead so i re-soldered it (black wire on minus, white wire on plus) but that didn't help.

any methods are welcome below, but avoid putting expensive methods first
