MGZR 160VVC 2004 Rear Demister!!

Hi guys, I must be going crazy here - PLEASE HELP!!..



I had a spare rear screen push button/switch unit that I swapped over but still no good and the light on the switch does not come on - surely that means its the fuse either from under the steering column or the bonnet?? I have researched about 20 different drawings on Google and on here to see exactly what fuse but to no avail...I have checked all of the 10amp and 15 amp spade fuses and they all seem fine - please please someone help?!...



Surely it cannot be a broken wire in the boot lid wire loom as the light on the switch unit would still come on would it not??... Could someone please put me out of my misery and at least tell me where the correct fuse/s is/are for the rear demister/switch?



Thanks so much!! :-)
