In the heater box, should be under the pass.side of dash, they have doors inside operated by vaccum, check that they are moving, if not, ck that you are getting vaccum, if so, ck the actuator running it. You can normally grab it with your hand and move the door & see if that gives you hot air.

Heat dont work


no heat is cause by many things (coolant not at 180F and holding?)
no blower?
damper closed.
as you said the water valve.
location:
see heater, see the core, see the 2 brass tubes passing thru the fire wall. ? they go to hoses. and if car has a valve its there.
some cars dont use a valve at all.
ill look yours up. USA spec car. bingo on valve.
so here is 91, camry. im looking now, its just like i said above
at the fire wall hose; to heater core.
what i do is here.
1: engine hot?
2: are both above hoses hot, (no fail, yes, good.)
here is a list of every heater failure possible.

http://www.fixkick.com/AirCond/heater.html


it's only 2 rules.
air must flow
the hot water must flow.
or it fails.


you can look at any time at alldata.com
or buy the FSM. for best play, (i promise)

Heat wont work


never post a car with no year, they make changes every year.
1990 to 2002 , ? and is a Toy Corolla in Snake skins(geo)
geo was 90-97/ only. 1.6L or 1.8L?
like heater water valves, or heater damper only heat controls.
ok.
so the fan runs at full speed?
the engine gets to 180F and holds?
ok not knowing year, ever see the 2 hose from engine side, to
cab side heater core. the that pass thru? well that is the cab core.
and you get engine hot and touch both hoses. are they both hot
yes, good, if not we work that.
this take like 1 min to do , after engine is hot and works on all cars.
1996 major changes. so?

here is a no year, answer on the controls
when you move each lever, it move a cable (does it) and if does
does the end of each cable move an object.
1: a water valve.
2: a blend door.

the cable has 2 end, either end can fail.
the cable has sheath, just like a bicycle and works the same way.
the sheath is has clamps if broke the cable is rendered useless.
use tie warp to clamp this floating sheath to any near object.
done many.
on old cars, i back flush all coolant paths and test the water valve if found. then when all together I have full flow through the heater core.
one guy had mouse nest in core, blocking it.
the system is real simple
hot water must flow thru the heater core. at 180F or more.
and air must flow through the out side of this core and past
all the way through it, and arrive at the vents
if the core is hot, then the flow is bad.
bad damper ,mouse nets. or some pack with leaves.
you now have all you need to fix it.

read this, they mostly bounce off walls but find it.

What if you leave the heater hose outlet off your car will your car run hot


Won't run hot

The heater hose is to put hot coolant
into the heater core for cabin heat, just won't be
hot inside

You have to put the two hoses together if you
don't want to have water thru the heater core,
then they don't do anything but circulate coolant
but not inside the car

Air con clutch not kicking in but just refilled with refrigrant


Taurus does not use a heater control valve. It runs coolant thru the heater core constantly. You may have a temp blend door actuator problem or a plugged up heater core is also very common. Feel the heater hoses, they should both be very hot, it one is much cooler; you can try to back flush the core.

2001 FORD EXPEDITION XLT 4.6L V8 BLOWING MILD WARM BUT NOT WARMING THOROUGHLY. HAVE FLUSHED COOLING SYSTEM THREE TIMES, AND CHANGED THERMOSTAT. HAVE ALSO REMOVED DASH AND REPLACED "BLEND DOOR" AND BLEND...


You hot air comes from the water circulated through the heater core. It is like a miniture radiator with water flowing thru it constantly. So by opening the "Blend Door" you are permitting so much of this hot air to pass thru.

Seems like for some reason your heater core is plugged up. Just like a radiator can be. So water may be passing through your heater core but not passing through fully. Your heater core gets hot from water passing throught it from the engine. Then your doors open up, in proportion to how much air is permitted to pass over the heater core.

Suggest to remove the heater core and replace it. Seems the blend doors are working properly but again, if you have a non working heater core then no air can pass over the "Hot Core" for you to recieve hot air.

If you are not mechanically inclined, then go to a local parts store and you can buy a car manual, such as Chilton's or Hane's Car manuals, for your year and make to show you how to replace it. Then you can also have it for any other problems that may arise.

Heater not putting out warm air


two things,

one the air does not pass thru the heater coil.
check the vanes of the dust if it is opening and closing as you switch the levers.

2nd the water valve to the core does not open to let the hot water in to the core.

check the valve if it is stuck close. feel the hose if it is getting warm as water passes thru.

tnx 4 using fixya,
