118 M Sport Lost Power To Aircon Unit And Lower Button Panel

Hi all

Was driving along today as usual and noticed that the buttons, screens and functions of my aircon , fan, heater was completely dead, also I have lost illumination of the lights on the panel below (parking sensor, asm etc),

I remember this happening very briefly when I first got the car but it fixed itself after a couple of minutes so I just put it down to being a glitch.

I hae checked all fuses to do with the aircon etc and all seem to be fine,

its almost as if the loom has come loose at the back of the aircon, is it easy to access behind ther?, and has anybody had a similar issue?

Many thanks in advance

Stephen
