you put your wooden mold on the machine and then you put the plastic over it and then u melt the plastic and you pull the leaver up and you wait and then your done.
The heater/ac doors are all electric. They are not vacuum controlled.
Any of the following................... 1. Low coolant level. 2. Clogged heater core. 3. A/C heater controller bad. 4. A/C heater doors not working. 5. Vacuum problems........
The first thing that you need to do is check for a vacuum leak for the a/c and heater system, this is a very common.............
The heater blend door is not run by vacuum. It is run by an electric actuator.
if im not mistaken the heater control has vacuum lines. take off heater controls and see if you have a bad vacuum line to heater box.
The heater control valve is used to shut off hot coolant from entering the core when the heater is in the off position. A heater control valve can be actuated by either a vacuum line or a cable from the vacuum heater control valve to the heater core. This hose should be warm; if not the heater control valve is stuck and needs to be replaced
the heater controls are run on engine vacuum. When a engine is accelerating it has a drop in vacuum. There is a one way check valve that keep vacuum in the heater circuit that has gone bad. You could have it fixed or you can deal with it, its not that big of a deal
Where is the vacuum pump for the heater located in a 1995 Ford F-250 Diesel? Ihave already changed the thermostat and the antifreeze, checked the heater switch and still no heat! Help

Most all of the vacuum lines will start from the intake manifold in the rear..........
If it's the one in the engine bay you talking about, there is one that connects to the heater tap on joint to the heater hose.
