2005 Volvo XC70 Question: The heating system do not work ...
By morning when it's freezing, I put the heating system on "automatic" mode and set maximum temperature. I have to drive for some kilometers and normaly only after some speeding up it does start to warm the cockpit !!! However, in Summer the air condicioned works ok and it lowers the temperature very rapidly - FDelgado

Have you thermostat checked, it may be stuck open, causing this problem. If this is the issue, the check engine light should come on though, is it on? - Bret Bodas
