Can anyone point me in the right direction here? My EL Ghia climate control is working all as normal, with no fault codes, however it will NOT go to demist, everything else seems to work fine. What do people think is wrong and what can I test?

Cheers, Gab

possibly vacuum solenoid control unit or hose fault or wiring refer to tech docs - try applying vacuum to different hoses (demist = yellow I think) with fan running and check for demist also possible faulty actuator(dash out)

Normally it should default to demist with no vacuum.
Check out the demist/floor flap with a torch, while cycling it from the CC panel. You'll have to get your head in near the drivers footrest, though.
They do break over time - normally though I'd expect it to stay at demist.
