Aircon cold only

The drivers side aircon is blowing cold air only regardless of the temperature setting.

Noticed because my feet were getting colder and colder this morning so switched it to the main dash vents to check. The central passenger vent blowing hot air, the drivers vent right next to it cold only. Same for all the other vents.

The temperature setting seems to have no effect at all. The switch itself seems ok as when aircon in sync mode the temperature of the passenger side air is effected by changing drivers temperature control.
