I can tell you this from memory I think? Vacuum control valve for hot water circulation will be in line on a heater hose going to your heater core which will be in the right/ passenger fire wall area Vacuum control valve is located right behind heater ac control. Vacuum damper for hot or cold air will be located near the heated and ac coils under dash on passengers side mounted on a duct either on the heater core box, or in that area. I can offer you a site that will have the exact info your asking for also, problem it cost 20.00 to buy a service manual, but it cover every system on your car that the service men use when they work on cars. www.alldatadiy.com. I use this site almost daily. Merry Christmas!

Hi, the blend door is not vacuum operated; however the veater water control valve is. Check to make sure the heater control valve (see pic below) is opening (vacuum motor should turn valve lever). If that's good, check the adjustment of the blend door cable. Make sure the door opens fully when the temp is set to hot. Please let me know if you have questions, and thanks for using FixYa.

1997grand voyager is blowing cold air new thermostate water pump and the raditor and heater core has been back flushed it started blowing hot air again then went back to blowing cold air again


I would look for a vacum leak on the control valve for the heater. There are 2 lines from the radiator leading back to the firewall. One has a control valve on it that should be vacum controlled. When you back flushed to the heater core you may have forced this valve open temporarily. The control may have low vacum or insufficient vacum to open a stuck valve. The good news is you can actually manually open this valve and tie it in the open position which will at least temporarily solve the problem. Check your vacum lines for leaks and check the valve to make sure it isn't sticking.

When both heater controls are put on hot I get warm air on the passenger side and no heat on the drivers side.


Sounds like you are not getting enough hot water to the heater core. Check the heater control valve to make sure it is operating properly. If it has a vacume line disconnect it and make sure there is plenty of vacume. If not enough vacume find the leak and repair it. If it operates electrically make sure there is voltage if there is voltage then make sure the valve is opening all the way if not replace the valve. If the valve is opening all the way you may have an obstructed or plugged heater core.

Fan is okay on heater but no warm air coming out.


It sounds like the valve may be stuck or broken that provides heat to the core. First check your water/fluid level in your radiator. If that is full then you want to look for a valve that is occassionally vacum operatedon one of the two lines, about 1" in diameter, that run from teh radiator core to the Firewall. normally these are on teh Passenger side. Look at this valve and see if it is vacum operated or manually operated by a cable. If it is cable operated make sure the cable is actually working, if it is vacum operated make sure you can open and close it by hand and that you have vacum on the line. If vacum is present and you can operate it by hand then the valve itself is faulty. Same if you can't operate it by hand. If there is no vacum you have a vacum problem and most likely need to trace teh vacum line back to it's source and or replace it. The Haynes repair manual for your vehicle will be able to assist you further and provide pictures and diagrams of teh system to follow.

I have a 1998 e350 cargo van and the heater won't get hot. replaced the hot/cold button. cant find where the heater control valve goes. or if that is the problem. what should i try?


Check the heater hoses going into the heater core.Both of the hoses should be hot to touch,when the engine is at normal warm running conditions.If only one,or none of the two hoses are not hot,or very warm.then pull the heater hoses off,and use a water hose to flush the heater core out.Make sure the coolant level is full,if it is not,then the heater core will not get coolant flow threw it.

you may have a bad control valve or the vacum liner to the valve is broke, it will be inline in the heater core hoses and havd the vacum to the top of it. most newer ones are made out of plastic. if they do not open you will not get heat

Heater is blowing cold air,


Check operation of heater coolant control valve, and it's associated remote control mechanism.
Check that both inlet and return heater hose is equally warm, as this indicates coolant flow through the heater core.
If no coolant flow:-
Check cooling system is correctly filled, taking care to bleed off any air locks from the system as necessary (with heater coolant valve open);
Check heater core is not blocked.

Heater in my 99 gmc 2500 is not working


They could be related but most likely not. There are two water lines which go back to the firewall from the radiator. On one of those lines is going to be a controller that is cable or vacum controlled. If it has a vacum line you need to check the vacum pressure at the connection using a vacum pump. You want to make sure that valve is opening and closing accordingly. If it isn't then your heater will not work because no water is getting to the core. In this case you will need to isolate the vacum leak back to the source of the problem. If there is a cable connections make sure the cable moves freely and in sync with the cab control. If not replace the cable. Assuming the radiator is full this valve is the next place to look for a fault.

Heater blows cold air


Have some one watch the heater control valve, under the hood tapped into the feed hose for the heater core, and while you switch from hot to cold they should see movement, if not it has to be checked for vacuum feed and or replaced.
