Just a question but when does the air conditioning on my C36 actuallt turn on? As far as i can tell, if you set the climate lower then the outside tempeture reading outside, the air con turns on. How exactly does the air con turn on and when?

The a/c compressor should run any time the control unit is on, except when the EC button depressed & light is on.

so the AC should run even at HIFG temperature settings?

as far as i can tell..i started to keep notice fron day 1 when i got my car about how the AC works.
