Juan, the most common cause of the heater to not work and blow cold air is
because of low coolant or air in the system. We have an article that covers
other reasons, see the following link.

Hello Dennis
I have a question.
i have a 2000 ford taurus that the vacuum line for the hvac system broke
off.
i tried to reconnect it but the line got pushed behind the firewall.
my question is do you know where that vacuum line connects inside the car??
it’s stuck in defrost and no heat and i believe the ac comp comes on as
well.
but the air is just cool not cold.
please help no heat..
Hi I have a 2001 dodge ram 2500. Not all the time, but some times I get
smoke coming from the entire dash including the vents. I don’t have to have
heat/a.c. on and it still smokes.kinda like steam.when I accelerate more
smoke comes out.. any suggestions on what the issue is?
Hey i have a 2005 Volkswagen and my heat just somehow stop working. It

good. Whats your opinion on that?
I have a 09 dodge journey sxt…dual climate control. Im only getting heat
on the drivers side, and cool on the passenger side. I replaced the blend
door actuator, fluids are full…I have no idea what to do
next…HELP…its 20 degrees
I have a 2010 Lincoln mkt the heater working all over except front
passenger side it blows cold air
my 93 4runner stopped blowing hot air I had the coolant changed but it
still won’t blow hot air and now it is overheating do you think this is a
blocked heater core or another problem. there doesn’t appear to be any
coolant loss and I’ve changed out the thermostat
I have 2000 ford expedition that blew cold are so I just had the thermostat
replaced and new coolant and and now it’s a little better but still doesn’t
give off that much heat what else could be wrong with it
I bought a 1999 ford expo,Not sure about the thermostat that i just
bought,i will go ahead and fill up my cooling system first as you
suggested,because my heater is blowing cold air,Hope this soles that
problem.
Only one side of my car blows warm air the passenger side only blows cold
air. Any suggestions.
i have a mitsubishi lancer and when i turn on the heater it only blows cold
air with alot of noise probably the blower heater and also alot of
vibration that i can feel on the gas pedal on the highest setting of the
heater
My 1992 1500 4.3 heater is blowing cold air, I changed out the water pump,
thermostat and heater core. The blend system works properly and with the
engine hot the hoses to and from the heater core are cold. The only thing I
haven’t done is to check the switch on the dash. Is there a valve in the
engine compartment that can be checked.
My Chevy blazer does not heat i don’t really know where the coolant would
run threw on this
I have a 1994 Jeep Cherokee. For the last couple of days, when I turn on
the heat, it doesn’t come on right away. It makes a noise like it wants to
come on, but it doesn’t right away. And today when I turned it on, nothing
came out and it never turned on, I have antifreeze in it, but it wouldn’t
warm up making it hard for me to drive because the windows are fogging up .
Would you possible know what maybe wrong?
Hi, I have a 2003 Trailblazer LS 4×4 4.2 6 cylinder. I recently had the
coolant system flushed and a new thermostat installed, yet I’m still
getting cold air. I had the dealer mechanic check it out and was told the
water pump has some slack and the fan clutch was damaged. Would those be
reasons for still not getting cold air?? Thanks for your time!
You saved me a visit to mech and spending some not needed money.
This was exactly my problem and is fine now after increasing coolant level.
Thanks a million.
Hey Dennis, we have a 2004 Jeep Liberty that puts out normal hot air when
the Jeep is moving, but when we come to a stop, it now put our cold air and
when we start moving again, it put out normal hot air again. What could be
my problem? Good Video…
I have a 2000 GMC Yukon few months ago had the thermostat changed now when
I drive blows warm not hot air. When I’m stopped at a light it blows cold
air. Also noticed that the temp gage does not hit where it is suppose to
be. Could this heat problem have to do with thermostat?
My car Toyota highlander no heat .what can I do
Hey!
I have an 2007 Altima, when it’s cold out like now(October) the heat takes
about 25-30 min to turn on! When the sun is out it turns on a lot quicker.
I replaced the heat/ac unit controls, AND replaced the relay for the fan &
blower thinking that was it ……it still takes forever for the heat to
turn on when it’s cold. Any direction you can point me in?? Please help,
thanks.
this video should be called how to put water in your vehicle
I have a focus 01…I have to play with the fan speed on the dashboard to
get hot air…after few time..the hot air start blowing….any
suggestion?..thanks
Hi I have 2001 ford expedition and the heater just blows out cold air and
when I checked the coolant its topped off and my truck engine shows its
cold what could it be
I have a 2001 Ford Expedition that the fluid level is fine already checked
it runs at normal temp but still will blow nothing but cold air. Where
should I start I don’t want to replace things that are not broke. Please
help
i have a 97 civic changed the termostat on sensor next to it and check my
relay and still not heating
I had no heat in my 01 blazer. I changed the thermostat and now only get
heat when I give it gas. What could be the problem now??
i have a 03 escape and my heater only works on setting 4 but not 1 2 or 3
any ideas ?
my big rig cab heating is not working properly. The temperature guage
doesn’t rise while the truck is moving but it rises at idle or when then
the tuck is parked. The bunk/sleeper area will heat but the front driver’s
area will not. There are dual controls . Coolant Levels are normal and I
don’t see any leaks of coolant anywhere. Any idea what my problem may be? I
am guessing thermostat or water pump but don’t want to waste money paying
for a mechanic/shop to guess at it.
Hello
I have 2006 expedition no heat coming out in the front only in the
rear. What could my issue be?
When it’s hot my car blows hot. When it’s old out it blows hot for a
minute and then back to cold. All fluids are full and topped off. So what
do I do?
I have a 2008 Crown Victoria Police Interceptor. My heat works only when I
am driving at a high RPM’s. My fan speed seems to be what is broken. Any
ideas?
I have a 1996 Toyota tarcel and neither cold air or hot air blow! Do you
know what might be the cause of that?
no heat 2010 ford explorer v6 replaced thermostat, put fluid through heater
core flows freely in both directions, but when engine is running return
line just trickles out checked for restictions from thermostat housing to
the core and it is clear, engine runs at normal temp not overheating the
only thing I can figure is the waterpump is not putting out enough
pressure? I am at my wits end ready to get rid of the vehicle.
so I have a 2009 Silverado with less than 60k miles on it. When I turn the
knob for warmer air, nothing changes, the air temp comin from the vents
doesn’t change. The A/C works fine, it will get colder with that on. Is
this an electrical issue?
If you don’t have any heat… 1 top off the coolant. 2 replace the
thermostat. 3 back flush the heater core with a garden hose. Good indicator
of a clogged heater core is heat only at higher rpm. You only get heat at
high rpm because the system is still forcing some hot coolant into the core
but it quickly cools because its not being cycled properly.
I have a 96 gmc 5.7 liter pickup. My problem is I have no heat at all. I
took it too goodyear and they automatically assumed it was the heater core
without even checking the thermostat. They put coolant in and it some what
worked but they went back cold again. We don’t have the money too put a
core in. What’s the easiest way too do it and get heat so we can move
what can i check, have a dodge caravan 3.6lts, the heater works after the
engine gets warm, do not loose heat after works, notice the engine takes
longer to get warm, this happens only during this winter>>>thank you>
checked cooling refilled>
Thank you i found them.. thank you for you tips very appreciated
my heater works but does not blow to the windshield on defrost.. how can I
fix this myself?
Where do i find these wires for a 99 Buick Century
what if you have no heat and a strong smell of antifreeze in the car? i
replaced thermostat and checked coolant levels.
Thanks! I just bought this car for commuting So we I went to check the
fuses the blower fuse was missing. If I replace the motor will I still need
the fuse?
ok I got the fuse and it blows!!! Yea me! But still not hot air so I also
bought a thermostat. Do you know where the housing is on a 96 Hyundai
elantra? I followed the radiator hose is the housing directly under the
hose?
My heater blow warm air then get cool air
