If the CCU is calling for cold, the valve should be closed. If -12v is present on the connector when heat is selected, you have a CCU problem. Removing the electrical connection is pointless if no -power is going to it. I have heard of the valve sticking, and not allowing coolant to flow.

EDIT: corrected- thanks TF007
