Actros Fridge / Coolbox

I’m using another blokes truck this week and it has the factory fitted fridge. I have put the dial on max setting but it don’t appear to be working…as in not getting cold. There is no manual in the truck so do any of you lads know if there is another switch somewhere to turn the thing on?

There is a switch looks like the air con button but has a square around the snow flake on the dash has a red light to tell you if it’s working

Thanks a lot mate. Now working :smiley:
