L322 heater cold vent hot feet

Hi, I've searched the forum but cant seem to find anyone with the same issue as this. We have a 'project' 2004 l322 td6. Thought I'd fixed everything until this morning. Footwell, windscreen and rear vents blowing nice hot air - centre dash and front window vents ice cold. Middle knob thingy set to three red dots. I've checked the Bowden cable is attached and seems to be doing something. It doesnt matter what setting that is on - blue dots or red! Any clues on where to look next? Thanks, Ben.

Stuck blend motors on the heater box would be my next port of call....

(Yes, the L322 suffers from those too!!)

Many thanks for the quick reply. Unfortunately a lot can happen in a day of Range Rover ownership. Currently waiting for the AA as my 170000 mile gearbox has just gone bang!

Might still try to fix the heater so I'm warm while sitting in it crying....
