I replaced the heater core In the 93 caravan. Now, I'm Still not getting warm air. I believe the vacuum controlled valve and hoses are not correctly installed. I cannot find a diagram or picture of the correct routing. I have confirmed that the control valve is operating properly. Also need to know which side of the heater core is the inlet and outlet. Pictures or a diagram would definitely help. I Also plan on comparing this van to another fully functional one.

The vacuum operated valve that allows hot coolant to flow through the heater core. It has three hose ports and one vacuum tube. I found a blend door actuator that was stuck thanks to the guide all fixed!
