QPV AirCon blowing hot on passenger side

[Zep]

To be clear, ModelT's issue is the sensor. The original post before this was about it being too hot, and that seems like the actuator.

And yes, the sensor will be in the controls. Clean the grille first as lack of airflow will cause this.

Now if I could just find the temp sensor(s). I have a horrible feeling they are part of the AC control panel. Cannot find anything on Eurospares other than sensors which look like they are for measuring treated air. There seems to be two small grills each side of the display on the AC panel so I think that may be them.

Part 6 isn't it?
