HI, I have the same problem with my pathfinder 2002 LE since today!!!!!!! The fan always stay ON. Did you find the origin of your problem?
air conditioning and heater control
It is on if you selected it by pushing the button.
You exit a surgeon simulator by right clicking the surgeon simulator, and then hitting the Control and Alt buttons before finally hitting the F5 button. This does the trick.
It is for reducing petrol when climate control is switched on
by hitting the the X button or the triangle button

If you have a remote that locks/unlocks your door when you push the button. It's the same kind of control that is used to activae/deactivate alarm systems.
Turn the ignition on. With the climate control turned on, push and hold the recirculation button in. While holding the button in, push and hold the off button in for 3 seconds or until you hear a beep.
press off and warmer buttons on climate control center. warmer is also the pass side heat button.
If the climate control on a 2003 Trailblazer will not switch from feet to head vents, try changing it to defroster then back to head. The mode button on the dual climate control model can only be switched from face/feet to feet and then to defrost. The feet and head vents worked at the same time.
you go to the control panel, by hitting the start menu button. From there go to user accounts or similar depending on what you operating system is. from here you can add a password.
The A/C reset button is located in the climate control system. It includes the Fan, Temperature and Mode knob. You can set the A/C to vent, defrost, defog, and floor.
