Have you been through the trapdoor in the ceiling of the corridor yet?Ã,  If not, you have to go there first; disregard the rest of this until you have.

Now, there's something you can do in the room with the eye that the eye doesn't like, and that it asks you to immediately undo.Ã,  There is a way to make it non-undoable.

Or, if you want absolute explicit instructions, here we go: Use the broken wiper (which you should have gotten from the top of the plane) on the button in the upper right that controls the heater.Ã,  This will break the heater controls and make it impossible to turn the temperature back up, and the eye will be uncomfortable and leave.

I've explained this kinda as if it were something one could logically deduce, but to be honest I think when I played the game I only got this "puzzle" by trying objects on each other more or less randomly...
