I have a 2006 S40 FWD 2.4i and I am having sporadic problems with my air conditioning. What happens is, occasionally I will turn on my air and HOT AIR blows out. During the course of the entire day no matter how long I run it for, it continues to blow out hot air. <p>Volvo is telling me it will be fixed with a software upgrade. How many people have had this problem and was it fixed after they upgraded the software?<p>Thanks!
