What kind of climate control does a Volvo have?
There are two basic versions of the climate control system, Electronic Climate Control (ECC) and Manual Climate Control (MCC). •ECC: In AUTO, the CCM automatically regulates heat, air conditioning, recirculation and air distribution until the selected temperature is achieved. The ECC can be also combined with the Interior Air Quality System (IAQS).

How does air flow in a Volvo S40?
In the S40 the air in the passenger compartment passes through the parcel shelf into the cargo compartment. Then the air is extracted through non-return valves that open with overpressure. In the V50, like the V40, the air is extracted through non-return valves that open with overpressure. AIR FLOW
Why does my Volvo S70 have no AC?
Symptoms on my 1997 S70 was either there was a quick fan blow, everything stopped then the two lights flashed for 20 secs or nothing happened the two lights just flashed, no A/C and no fan.
