AC temperature selection works fine, just only blows into the footwell. Read that disconnecting the battery for 5 mins, then turning the ignition on should re-calibrate the system. I can hear the blends doors moving when I try this, but still no ability to select footwell / dash vents / screen.

Has anyone any suggestions before I go on the hunt for a used module ?
