My Silhouette had that same problem. I found that the coolant level was too low and not circulating through the interior heating system. Once I topped off the coolant it worked properly.
I just completed repair of the original problem that caused the coolant level to go down in the first place which was a bad lower intake manifold gasket. It now works great and doesn't consume any more coolant.
