Octy with split CC.

Do the air vents in the centre of the dash produce warm air, mine will only give cold when conrols are set LO and no air at all when set above LO?

Result LH is cold when driving and right hand warm.

Lastly when temp set to HI the air vents at the side of the dash and footwells only produce warm air, nowhere near as hot as I would normally expect.

I think the vents in the centre are used to balance the heat in the cabin by introducing cool external air. The LH cold RH warm thing shouldn't really happen unless you have changed the temperature setting suddenly by a few degrees so the climatronic has to work really hard to alter the cabin temperature.

The lack of hot air on the HI setting seems strange though. Maybe a sensor or something.
