Where does the hoses go on the heater control valve


The hose from the water pump should be connected to the heater control valve. The other hose goes to the return from the heater core.

NO HEAT


May have a clogged heater core, feel hoses going in and out of heater if they're warm, suspect blend door actuator under the dash they like to break! Sometimes they make a faint noise when switching from hot to cold. If hoses are not hot check the hoses for a valve usually vacuum controlled. Have a helper play with the heater controls if the vacuum doesn't exist to the valve it won't open. If you have vac at hose valve is bad. Rate my answer and let me know how you make out

The heater temperature control valve is stuck when you change temp at switch valve is no opening all the way. could have just come disconnected. It is located were the supply side (in) water hose goes into heater. check it . Check your heater control panel for louse vac line at the dash.

Temperature control


Well I thought a 92 model used a vac control valve on one of the heater hoses, but I don't see one listed.
If there is no control valve, the temp is controlled by blend doors under the dash.
Something is not closing the air from the heater core, or blocking the hot water from flowing thru the core.

There should be a vac controlled valve on the heater hose near the firewall. If that valve fails, or something happens to the vac source, the valve will not open or close. I would check that valve and make sure it is working. Both heater hoses should be hot when the engine is warmed up.

Won't idle when a/c or heater is turned on


Sounds like vac leak to heater control valve. Small vac line leading to heater control valve (in heater hose) is either off or cracked. So when you engage heater or AC it sucks air.

Heater and Air conditioner work bur air flows from window vents only. Can't change direction of air flow to different vents.


There may be a couple of items to look at here.... but the most common problem is a source of vacumn to the pneumatic operation of the heat/a/c vent doors....if vacumn is not distributed properly to the vents you command it is assumed that there is either no vacumn to the selector swith panel(broken vac. line,kinked vac. line, defective in dash a/c control panel) or under the hood a defective vac./heater control valve that is stuck,frozen, not allowing the vacumn to pass through it to supply the indash pneumatic controls and/or panel.
Most vacumn systems that i have ever came in contact with incorporate a vacumn supply tank(nothing more then a round plastic vac. resevoir) which is used in sequence with the a/c heater controls, its purpose is to keep an even vacumn supply to all command points continously while the vehicle is being driven, without this supply one will experience the a/c coming from various different non selected dash vents upon acceleration, this is a direct relation to the tank either being defective(leaking vacumn) or its supply hose(usually vey tiny rubber/plastic tubes) being pinched or broken not allowing the vacumn to the supply tank.
listen for vacumn leaks(hissing sound), look for the obvious...broken vacumn lines or hoses, also check for a defective one way vacumn valve on some pneumatic controlled door vent systems(these valves are inserted in a vacumn line one side being the ""in" port and the other side of it being the "out" flow port,typically if these dont work the vents will also devert your a/c or heat all different ways through your dash.
to check these valves, simply remove from the vacumn hose, and apply vacumn to one side,if vacumn flows through the valve, apply the same vacumn to the opposite side of the plastic valve, if vacumn flows through on the opposite side the valve is bad, it should only allow flow from one side not the other. These valves are small and are usually white or black plastic and look like the old vacumn dash pots used on the old carbureated engines only smaller with one small hose in and one small hose out.

2001 Lincoln LS heater blows cold air...someone said it was the DCCV Dual Climate Control Valve on the front of the car. I am looking for the inlet hose from the valve to the heater core...is it the...


When the engine is cold,check the coolant level.

Make sure it's on max.

===

A coolant system should be flush every two years.

===

If you did a coolant flush recently then air pocket can be the cause of the un-even heating problem.

The DIY method is to drive you car onto a ramp or a steep hill.

Iet the engine cool off and top off the coolant tank.

Set MAX heat + MAX fan

Let the engine ran for 20 minutes wih the cap off and the trap air will escape from the coolant reserve tank,

Check coolant level and top off coolant when the engine cools down.



A shop will charge $75+ for this but using an air operated excavate tool!

========

A car with over 90K miles may experience linkage problem to the heater control valve.

The heater control valve (near the firewall) may be stick over time.

Open the hood and move the heater to max and min. Back and forth.

Clean and lube the linkage with WD-40 to free the heater control valve.

If it's a vacuum type heater control valve then cash for leaky vac. hoses.


=======
Move the fan switch back and forth to re-new the electrical conductors.

Pass a vacuum over the control panel to prevent dust build up behind the console.

1986 buick lasabre heater fan workes, but no heat at all


could be a vacuum switch on the heater hose. The heater hoses are the small hoses ( 1inch, usually black or red) that run from the motor to the inside of the car. They should be warm when the car is up to temperature.

The vac switch controls the water flow to the heater core. If the vac valve is bad or the vac line that feeds it is bad it will not allow water to enter the heater core.

Could be a plugged heater core too.

Check the water level in the radiator as well. If the engine is low on water often the first to go is the heater.
