heater giving wrong temperature ? matrix? controls?

hello, took the centre of my dash off today ass the bulbs behind had all blown and the temp nob on driver side wouldnt go all the way down to cold, and when you moved centre nob the driver side temp nob would move slightly aswell, now the nob will go all the way to cold, the air comes out ice cold on pas sidebut on drivers side isnt cold just room temp :s any body got any ideas

the cables between lever and box may have moved in the clip were cable outer is held or fitted poorly one cable runs close too the other lever on heater box

yeah one of the cables was loose will have another look at it tomorow and wd40 the whole lot !
