Need help with L701 mystery connector

Today was removing rear window washer tube and found a unplugged connector by the firewall, circled red on the pic

Does anyone know its function?

If I recall correctly it’s part of the A/C system.

Thank you! That explains it.

Can confirm, it’s for A/C. There are multiple redundant plugs around the car, as well as the plug(s) for the power steering pump
