There is a lever on the rear vent that I slid all the way to the right. This turns off the cold air coming out here. In the summer, I might open it, if it's blowing cold air-conditioned air. If I was really worried about it, I might get the servos checked, but the system works.

Also, I get a fairly wide variation in temperature of the air that comes from the dash vents. Once on a long trip last winter it annoyed me enough that I turned the fan to "low" once the interior got nice and warm.

I think that the climate controls are a weak spot in these cars, but if it can be adjusted to give you heat and cool air as appropriate in the correct amounts, it's working.

The whole climate control system, to me anyway, is a bit mysterious. At least the system doesn't have to be constantly adjusted; the automatic temperature setting is cool.
