Santa Fe (CM - 2007-12) :: Heater Blowing Luke Warm Air
Dec 23, 2011
I have a SF 2009 Limited. Since I bought it 2 years ago, I noticed the heater blows luke warm air. Not hot. It takes 20min for the cabin to reach 22degC when it's only 0 outside.
It was like that when brand new.
It has the auto temp control, so it might be playing tricks on me but I don't think so.
I am tempted to find the pipe feeding the heater radiator and insulate the pipes. Maybe the heater only gets warm liquid.
What else can I do?

I have a weird issue on my 2008 Elantra. The heater starts blowing luke warm/cold air after running for about 1 hour or so and stays like that.

It blows luke warm air, no hot or no AC just luke warm... what could it be?

My manual heat/cold adjustment dial is working fine and transitions from heat to cold readily. However when in max heat, it is blowing luke warm. The higher the RPMs going down the road the warmer it blows (still not near as hot as normal), then idling at stop lights or in park it goes back to warm only.
My engine temperature is running normal at all RPM levels while driving and idling. Partially clogged heater core maybe, where higher RPMs force more water through it? I assume its not the water pump or thermostat since my operating temperature is staying normal...

My 2009 Santa Fe GLS a/c, heater, etc. blower has stopped blowing air. I have checked the fuses, did the push test on the air adjustment button but nothing has worked. Sometimes it's like I can feel a VERY SMALL amount of air blowing out the vents.

I bought a white 2015 Sonata GLS with 55000 kms on it. Car works fine but really great on gas in city with AC ( 11-12 liters/100 kms ).
And my main problem is my AC/heater vents. Its nice cool day out and I wanna roll my windows up and use outdoor air (with AC off and heating knob on cool - Blue side) but still blow warmer air (the more I turn the temp knob to less cool side more warm air comes out). I went to dealership and complaint about it but they said can't duplicate problem. And I replaced cabin air filter too, but still same problem.
I don't have automatic temperature climate control option, so its all manual, red and blue setting for heat and cold. I complaint them may be my heater stuck on heating but no action taken from them..

My Ford Explorer blows warm air instead of hot air and it's getting colder and my windows get fogged up. I fixed my clicking sound behind the dash.

My 52 Mercury Heater fan is working now, but the air blowing out of it is not warm and this does not change when I moving the temp lever on the dash. Is it likely just the heater control valve or is there something else possible wrong? I'm not finding anything online about how these systems work and my shop manual doesn't give me much info.

2007 GS 350 109,500 miles. My heater was blowing cold at idle and warm when driving so I took it to dealer. To my surprise, dealer says its a blown head gasket. No other symptoms. No white smoke, no smells, no warning lights on dash, and running fine. Just had VVT gear recall done last week.
Fortunately I have Lexus extended warranty good thru 125k miles and Feb 2014. I do my own maintenance (plugs, oil changes etc). Have records for all. But have not done coolant change (due at 100k).

This problem is on my son's 2000 F-250 5.4. It's into October and my son tells me he has no heat coming out of his vents. I figure it has to be the control valve that should be in the heater hose lines. Could be jammed closed or a vacuum line has come off the pot that controls the open close cycle. We open the hood and nowhere can we see a coolant control flow valve. It is so tight and dark under all that mess of wires, intake, air conditioner lines and whatever.
Just where should we be looking for the valve. Also it could be the vacuum line is unplugged on the dash, behind the warm/cool selector. And even there is a possibility that some doofus has removed something. He bought the truck this summer. So to get us on the right path, where we start looking for the flow control valve?

My '06 GS450h has developed a fault where the heater blows cold at idle and low revs but blows warm when driving or revving the engine at a standstill. The coolant hasn't dropped at all and the car never goes above halfway on the temp gauge. Its starting to get frustrating now the cold weather has set in and temps dropping! Long journeys are ok as at high speeds it stays warm but short journeys are uncomfortable!
I just had a feel of the rad hoses and hoses that go into the matrix (engine side of bulk head) and matrix hoses feel warm (both of them), the top hose to the rad is warm but not hot and bottom hose is cold suggesting the stat hasn't opened yet. Its cold outside so getting the car up to temp is quite difficult without a long drive (rush hour at the mo).
Still I just had the car parked on the drive and cranked the heater up to max and held the accelerator for a while and super warm air blows out. The engine cuts back out as "normal operating temp" has been reached for battery mode and then the heater goes cool again! Still the bottom radiator hose is cool and top hose not massively warm. It has never overheated thus far and I drive 150miles a day back and forth to Reading from Cheltenham 4 nights a week.
Only thing I can think of is a sticky thermostat or water pump not operating sufficiently enough to circulate the water? Its getting colder and short trips where it used to blow warm air nice and quickly (within 3-5miles) are becoming unpleasant!

My car doesn't blow hot air. the temperature gauge goes up to half way like it normally operates at but the air never get more than luke warm. I changed the thermostat last year with no better results and I just had the timing belt and water pump replaced in July. It been an average of 8 degrees here for the last week.
Its a 98 camry, 4 cyl, Automatic...

We got our first taste of fall weather in Houston this weekend, and with it I've discovered a new problem with my truck. After the engine was up to temp, I noticed that the heater would blow cold air any time I sat at idle. If you rev up the rpm's to 1500-2000, you can feel the air start to get warm again. I'm guessing this means my heater core needs to be backflushed.

I just changes the heater core, water pump and thermostat and I only get luke warm heat coming out of the vents. Did I need to have bled the heater core?

Nissan Frontier 2004 with v6, air, automatic 4x4.... I only have luke warm air coming into my truck. The switch on dash switches from defrost to floor or thru dash . Was thinking maybe a switch under dash not working maybe, but do not know where to start looking.

Just went on a trip to SC. It was hot as hell - 100F most of the trip. The a/c would blow cool (not exactly cold) for a while and then go luke warm (way better than outside but not particularly refreshing) for a while. So I was reasonably comfortable but definitely not cold.
This would happen about every 15-30min where I felt like the compressor had stopped working for a while. I am thinking the compressor is probably limping along and about to die. Usually I thought these things just up and die though. Clogged accumulator? IDK - nothing has been done to the a/c system since 2009 head gaskets.

Well I was recharging my a/c yesterday because the system was low so I used one of them 24oz cans and now I am getting cold air out of my passenger side and luke warm air out of my driver side vents. Also if I switch to the different vents I don't get anything out of the floor only. I get air out when I select it, but it's coming out of the defrost. Other than that everything else works just fine, just no floor. I've read issues with the blend doors but my vehicle doesn't have the dual climate controls so I'm at a loss...

When my hvac controls are turned to hot, I'm getting only luke warm air. When moved over to cold it feels like the a/c is on...granted it is 21 degrees here. What I've done so far:
1. Flushed the coolant system at the local COOP TBA
2. Flushed heater core-Both heater hoses are hot to the touch as well as the heater core itself. The hoses are within 10 degrees of each other tested by an infrared temp gauge.
3. Verified the blend door actuator is moving. I can see it spin while attached to the box as well as I pulled it out and plugged it in it will move from hot to cold.
4. Smacked the #$%! out of the blend door box.
The fan still functions as it should from low to high. The truck also gets up to operating temp as usual.
Is it possible the actuator is still faulty even though it moves and not going all the way to the heat side? I considered picking up a replacement but I hate to start throwing parts at it.
Did the blend door give up? The snow is here and I need the heat for those 4am waterfowl hunting trips.

This weekend was a nice high 80's low 90's. My AC is usually ice cold. However now that the weather hit that high, when we are in stop-and-go traffic, the AC starts blowing warm humid air. I do see the temperature need creep a bit higher than the normal range.
Once we start driving, after a few minutes, the climbs back down and the cold AC returns. Turning the fan speed down, or turning the compressor off, then on again, seems to work.
What could be causing this? A friend said he has this issue with his car claiming the engine is the issue, not being powerful enough to keep the compressor running right, is that possible?

I have a 2007 Dodge Charger. The heat blows out warm air. I have replaced the water pump and thermostat. When accelerating the vehicle, the heat turns to hot. Is this normal, perhaps a speical feature? I have 66,000 miles.
