BA xr6, ICC lights up (not the screen) but dosen't work, pulled apart the panels to get to it and unplugged the ICC from underneath and it turned on then turned itself back off after a day

Does this sound like the ICC is stuffed?

does anything work - heater fan -vent controls -radio etc. or nothing
connection for ICC is at rear when ICC is removed from dash- connections underneath are for BEM module-
is it working but in night mode -to change push and hold power button
if you remove ICC make sure you reset connector plug at rear by pulling toward you "slightly" until it locks
do reverse lights work -
try removing and refitting reverse fuse
check all fuses with a test light
have you had it scanned for codes
