ok, i have done a search but didnt come up with what i wanted
1 - my heater/aircon is stuck on demist, doesnt matter if i select head/feet etc, it stays on demist
2 - its stuck on heat, i can hold the cold button to override and it gets cold but... if i turn the unit off it starts venting hot air
3 - relating to above, i can select to recirculate the air but when the unit is tuned off it changes to the outside vent, hence it slightly blows hot air
