Question about 1995 Ford Aerostar
When the heat is turned on it will only blow out cold air
The aerostar has a vacuum operated watervalve in the heater tubing.the valve is located on the
passenger side inner fender behind the aircleaner.with someone operating the controls inside the van
you can check to see if you get vaccum by removing the tiny hose that goes to the water valve
and checking for suction as you in the van person operates the heater conthttp://www.fixya.com/PostAnswer.aspx?thid=1323651&prdid=696348rols. If you have no
vaccum there is a break in the hose between the intake manifold and the valve. If you do get
vaccum check to see if the valve changes position from vaccum on to vaccum off. you can see
this motion on the small lever on the side of the valve. If the valve lever doesn't move you can
move it manually to allow the water to flow through the heater core. if the valve won't move manually
there is an obstruction in the valve. If it does move manually the vaccum diaphragm is gone.
replace the valve. if it moves to the manual open position you can hold it open with a tywrap.
before you get to this point you should first check to see that there is enough coolant in the
radiator. If you still have no heat you can check the coolant flow through the heater core. to do
this remove both heater hoses from the valve and pump water from a hose into one of the hoses
water should flow from the other hose. If it doesn't the heater core is blocked. The rear heater
operates the same way with the watervalve under the van just behind the drivers seat.
