Perhaps an over ride for the electric fan? I have a pull switch which lights to indicate it is on for my fan manual switch.
Mostly it is off and I rely on the thermo switch but if
I'm say getting ready for some serious driving I just pull
the switch and the electric fan just runs till I push the switch closed. Kind of a security blanket for when I'm stressing the car.
I also had a "spare" hole in my dash. I just installed a
simple on/off switch to match the turn signal switch as a dummy switch.
It's there if I ever decide I need another switch for something.
My electric fan has a three way toggle; sensor/on (over ride the sensor)/all off. I rigged a light so if it turns on, either by the sensor or manual, I know it. I also rarely need the fan.
That was my thought on the extra hole too; mount a switch for future use, some day I can reinstall the cheap electric windshield washer pump if ever get "bored" and am looking for something non critical to do on the car.....fat chance!
