Aircon

[Gabegavie]

My Mercedes C200 K 2005 model W203 M271, is blowing cold air down to the pedals even though the aircon is off. Sometimes when such happens the idling change and become idling higher

..... Sometimes when such happens the idling change and become idling higher

For the car's computer to increase the idling revolutions, there must be a sensor telling the computer that the aircon pump is having to work harder.
What are the fault codes stored in the computer..?
