Automatic climate control issue

[Torvalds]

Hi lads , i own a Clio 2 with automat climate control unit and i have a tiny problem with it . I have the modes : chest and feet selected and the air blows only at chest area and nothing at feet if i deselect chest i get air at feet , same stuff happens with windscreen and feet , full air at windscreen and nothing at feet , deselect windscreen got air at feet , i went Reno dealer and they told me from construction reno didn t put something in it but the normal 3 button units with aircon have this missing bit and on those it s working fine , hope it makes sense english is not my first language. Thank you
