We had a GB years ago that Niko set up. I don't know the vendor he used but they are nice quality floor mats and they had both auto and manual options.
That threaded hole on the bottom of the hood latch support and the stud in the center of the lower bumper spoiler are attachment points for the plastic underbody splash shield.
The switch is in the latch I think the passenger side. Look in there and you will see a white plastic piece the moves up and down when you close the hatch. Your switch is probably froze from the lack of lube or it broke.
