With automatic climate control systems it's common for the air conditioning system to run any time the system is on. This cools down the passenger's compartment in the warmer weather and dehumidifies the air coming into the passenger's compartment in the colder weather. The dehumidification prevents the windows from fogging up in cool damp weather. I use the air conditioning setting year round in my vehicles for the same reasons. HTH. -Jim
