Well nuts, my fuse 48 keeps blowing randomly when I press the MAX A/C or windscreen defrost button... Interesting.
EDIT: SOLVED - for me, the problem I was experiencing was the climate control panel was fine after #48, 7.5A, fuse replacement with usual operation, just as long as I didn't press the MAX A/C OR the front windscreen defrost button. If I did, instant fuse blown.
I replaced my Final Stage Unit/Resistor (no its not fun but its hot that bad either, just got to move a lot of things to access) and after replacing, it works perfect again. I tested heavily before putting vehicle back together.
Then cleared faults in DIS 5.7 and away we went
