I have two switches in the car that I don't know what they do. One to the left of the center console where the radio is, it has a little LED on it but doesn't light up either direction I flip it.


The other is hidden by the driver's side kick panel and is just a push-type button.

The weird part is the wires just connect to the box, then to a ground, they don't go anywhere inside the cabin IIRC.

My driver's side fan works just fine, I hear it running sometimes.
