General What is this hole in the dash?

What is this hole for?

Cars with aircon have the cabin temperature sensor fitted behind here

Otherwise nothing

 

[DaveMcT]

When the aircon switch goes AWOL, it's a handy place to fit a pushbutton switch.

 

[Mickit]

Could be a good place to put a USB socket for charging, or a switch for DIY heated seats

Cars with climate control rather than just aircon.

aircon doesn’t need a cabin temp sensor, climate control uses the cabin temperature in conjunction with the sun load sensor to work out what temp the air coming out of the vents needs to be to keep the cabin at a set temp.

Correct

I realised soon after I wrote it but after the 15 mins window for editing

Full expected someone to point this out. But after a couple of months I had forgotten about it.
