Centre vent always cold, side vents always hot

[MikkiJayne]

Hi guys,

I'm sure I've seen something on the centre vent temperature control not working, but I can't find it anywhere It always blows cold.

Also, my side vents and rear centre vents are almost always hot, regardless of the temperature setting.

The windscreen vents are the only ones which appear to respond properly.

I can't see anything in Elsawin or the tech dump about fault finding so I'm going to try basic settings and all the output tests to see what happens, but in the meantime does anyone have any suggestions please? There are no codes stored.

Thanks
