Did you ever find out what was wrong. I have a 2007 Altima as well and its doing the same thing. The colder it is the longer it takes to kick in.

Takes 10 minutes to start working? Is this like an automatic temperature control vehicle? If so, you could have a blower speed controller issue, or a temperature sensor issue.

If it's basic ol' manual controlled ventilation system - check your blower resistor and wiring.
