In case you don't know--those two middle vents above the heater controls blow only fresh air. Whatever the temperature of the outside air is what you will get through these. All the others are controlled by the heater/air conditioner.

I agree--there is currently an active post on the cruise control issue. Do a few searches and you'll come up with a lot of info. If not, post back here and you'll get a good start on some advice.
