I've managed to loosen the wires from the terminal and place them in a correct way using a flat screwdriver that came with the other Ender 3 tools. After switching wires to correct position the z axis started to autohome correctly and z stop switch started working correctly. In the case of only the Z-axis of your Ender 3 failing to home, we can immediately tell that the Z-axis endstop is the culprit, meaning that either there are problems with its wiring (especially likely if you have been working on your Ender 3 lately) or the endstop switch is not functional anymore.

My new stock Ender 3 V2 is having extreme deviations in Z-axis homing. When I auto-home, The nozzle will end up anywhere between perfect print height to a full millimeter off the bed, seemingly randomly. Specifically, the Z-Axis no longer moves down (the X and Y axis seems to be fine). Not only will it not Auto-home, but going to "Move axis" in the Prepare menu will also not move the Z-Axis down. I have attached a video I found on YouTube that showcases basically the exact same problem I am having. q5ClMt.
