the brake light switch will work without the key in the ignition if you push on the brake pedal, its just the way its designed. if you were to test the switch with a test light one wire is always powered up and the second wire is only powered when the brake pedal is pushes to activate the switch. if you test both wires without pushing the pedal I think you will find you have power on both wires indicating the brake switch has shorted and is working all the time. replace the brake switch.
Push and hold the brake pedal in the applied position.
Push the switch forward until fully seated against the bracket.
Release the brake pedal.
Lightly pull the brake pedal rearward until the master cylinder pushrod bottoms against its internal stop. The switch plunger is now set at its proper clearance.
Loosen the switch-to-pedal bracket screw and slide the switch away from the pedal arm.
Push the pedal down by hand and allow it to return on its own to the free-hanging position. Do not pull it back!

Slide the switch towards the pedal until there is a gap of 0.140 in. (3.5mm) between the plunger and pedal arm.
NOTE: The pedal must not move when measuring the gap.
Tighten the switch screw to 82 inch lbs. (9 Nm). Recheck the gap.
Push the switch through the clip in the mounting bracket until it is seated against the bracket. The pedal will move forward slightly.
Gently pull back on the pedal as far as it will go. The switch will ratchet backwards to the correct position.

This procedure calls for setting the switch prior to installation. Installation directions are included in this one procedure.
Preset the switch in the following manner:
Pull the switch plunger all the way out until it is fully extended.
Push the switch plunger inward 4 detent positions (clicks). This will provide the preset position for the switch installation. The plunger will extend approximately 0.55 in. (14mm) out of the housing at this setting.
Connect the harness wires to the switch.
Press and hold down the brake pedal.
Install the switch. Align the tab with the notch, then insert the switch and turn clockwise about 30°to lock it in place.
WARNING Do not use excessive force when setting the brake pedal switch or damage to the switch could result.
Release the brake pedal, then LIGHTLY pull the pedal fully rearward. The pedal will set the switch to the correct depth.
not positive on this model, but most cars have the same style set up for the brake lights, as you depress the brake pedal, it moves away from the switch causing the circuit to close and light the brake lights. hope this helps
your brake light is always on because the stopper at the brake switch is destroyed that's why it doesn't turn off. just put something hard to fill the hole at the brake pedal.
Change the brake light switch on the brake pedal arm. Go down to the
parts store and ask for a new brake liight switch for your Pathfinder
and look up under the dash where the brake pedal arm goes and you will
see the switch. You will need to unplug the wires to your old one and
disconnect it and install the new one the same way. It is pretty much
self adjusting once the brake pedal is released. If the brake light
does not go out adjust the switch pin to be longer so it will depress
when the pedal is released
