Morning,

The climate control unit puts out hot air only. Turning the temp control wheel down to blue has no effect on the tempetature. Also, the vent flaps do not work. I can see how the vacuum would make the flaps work, but I just don't see how the vacuum could be used on the temp wheel to set the temp. Tomorrow I'm going to start working on this after thinking about it for a couple of years. I know that either my ccu is shot, or a vacuum leak is somewhere - I'd just like know about the temp wheel before I start.
