There it is!
Here's why I couldn't find it. Until you push on it all you can see is a little arrow / triangle thing. Doesn't look like a trunk latch switch to me.
I was there a whole week and I was never able to hit the right switch when I wanted to turn something on or off. I invariably hit the wrong switch two or three times before I hit the right one. You can't tell just by looking whether any of these switches are ON or OFF. In this case the Night Light switch is on and all the others are off. Or is the heat switch on, and all the others off? Do you see the problem?
