Intrepid :: 98 - Heater Will Not Blow Hot Air When Idling (just Warm)
I am having a problem with the heater on my 98 2.7 Intrepid. Will not blow hot air when idling (just warm). After several minutes of driving with heat on air temp goes from hot to warm. It might just be me, but it seems like the air flow is cooler coming out of the defrost vents than from the dash/floor vents. Thermostat has been replaced (proper operation verified before installing). Had to replace gooseneck and heater coil supply tubing due to a leaking bleed valve. There appears to be NO air in the system.
Heater core was backflushed, there appears to be no restriction. Hose temp on exit line is approx. 15 deg. cooler than supply line when fan is running. Blend door actuator was replaced last spring (motor shorted). When temp control is moved from hot to cold temp changes drastically and door can be heard moving. On-board ATC diagnostics indicate all is good. Engine is running at normal operating temperature, not overheating or running cold. Is there a cabin filter or inlet supply for the air that could possibly be obstructed? Air flow seems adequate, not restricted. AC works fine.
Suburban :: 2000 - Heater Blow Warm But Not Hot Air
I have a 2000 suburban with a 1500 motor and 300000 miles. Last year I replace the water pump and the thermostat. The heater would blow warm but not hot . But only when I start to drive. Yesterday I decide to change thermostat again thinking the new one from last year was faulty. Now the heater only blows cold air .

I just replaced the radiator in my 2001 Elantra and now the heater will not blow warm air. Also the temp gauge on the dash stays at cold.
I have replaced all radiator hoses ...
New thermostat
New thermostat sensor
Sierra :: 04 GMC Heater Would Not Blow Any Warm Air Until Vehicle Moving
I have a 2004 gmc sierra and it is having heater issues. For a while now when starting it up cold it would not blow any warm air until the vehicle is moving. The other day while driving it would go back and forth between hot and cold.

Sunday I bought a 2001 f250/5.4 to replace my 91 f250. I didnt drive it yesterday, but this morning on my drive to work the heater was very weak, it seemed to blow warm for the most part, but was barely pushing air even on high. I flipped it over to A/C to see if it blew any harder and it did. Does the blower motor need replace? if so why does the AC blow harder than the heater?

The a/c and heater are not operating properly. Not cold enough and not getting warm. Low freon, compressor going bad?
On a brighter note...I've sat looking down into a volcano that could blow at any moment.
Ford Super Duty (1999-2016) :: 1997 F250 - Cold Engine - Heater Would Blow Either Cold Or Slightly Warm
I can't seem to get the engine temp to middle range on the marker, but yet my heater blows "to me" hot air. Even while sitting in idle for extended amounts of time I cannot get it to "operating" temperature. I would think if my thermostat was stuck open my heater would blow either cold or slightly warm air. I have the 5.4L engine with knn air filter and no cats.

I have owned my 2008 Rx 400 h for just over two months now and at the risk of sounding dense, am I right in assuming that when you are coasting along without the engine running, the heater will start to blow cold air? Everything works fine until you lift your foot off the pedal. This is my first Lexus/Toyota and hybrid so I'm not totally au fait with how it should be working.

I have a 2013 Prius 4. I'm not sure if there is a problem or not but the heater just seems to blow the same temperature of air no matter how high I set the temperature. The air feels lukewarm. I was driving 60 miles yesterday with the temperature set at 76. I had on a long sleeve shirt and polar fleece jacket and it never got to where I was really warm. Outside temp was about 50.

I took my 200000 mile Prius to a garage that is highly recommended and the mechanic stated that I need a new evaporator and expansion valve. He tested the car for a day. There was no time to do the fix so I arranged for a dealership that I trust to do the job. When they were ready to do the work, they detected no leak in the evaporator, but said that the compressor, expansion valve, and AC line needed replacement. (They showed me the leak in the compressor with special glasses.) After I called the first mechanic with the new info, he said that he could detect a leak nowhere, but, in the evaporator, and, at the expansion valve area. I am now stymied as to what I should do.

View 3 RepliesFord Ranger / B-Series :: 2004 - Heater Won't Warm Up While Idling
My '04 Ranger has over 240k on the odometer. Runs great and has never given me any issues. Everything checks out OK - all the fluids, filters, and whatnot are in good shape. No CEL or any other indication that anything is wrong (except for maybe the IAC valve and clutch slave.)
I've noticed, though, that when I fire it up in the mornings to let it warm up while I scrape the ice and snow off the windows, the heat/defrost will not blow warm air. It doesn't matter how long I let it sit, it will only blow ambient air through the ducts.
When I get going down the road, however, the heat kicks in, after a bit, and works very well!
I've not found anything that would indicate an issue with the blend door or any other component and this is the first vehicle I've had that did this.
Is it normal for a 4.0 SOHC Ranger to do this? Or is there something I'm missing?... It's not really that big of a deal, but I do find it a bit odd that it would do this.
I mentioned the IAC above - I think it's "sticking" every once in a while and, when it does, I'll hear a loud "thump" right before it idles down to around 1k rpm. I can't see how this would affect the heat, though...
Golf/GTI VII :: VR6 Heater Does Not Blow Hot?
I've only had the car about a month, and love everything about it. . . . but with the onset of cold mornings, I'm not very excited about the luke-warm air coming out of my heater.
It's reminding me of my old B5.5 Passat VR6 wagon and the annual heater-core flush that it required. Of course, the Passat was 13 years old and had 200k on it.
Ford A/C :: Heat Blow Warm Air But Never Gets Hot
2001 Ford Escape.
Blend door seems to be moving properly...(or at least the control arm is...) Truck gets up to operating temperature quickly enough.
It does blow warm air, but never gets hot...can't keep up with single digit temps. Every thing looks to be operating properly...
Ford A/C :: 2000 - Heater Won't Blow Hot?
2000 f150 heater only got warm.
Flushed system, new thermostat, new coolant. Then NO warm air. A/C blows cold. Checked heater blend door and actuator both intact and working. Heater core not leaking, system holds pressure and doesn't leak.
Is there another automatic valve that could be shutting off flow to heater core?????
Passat (B7) :: AC On But Will Blow Warm Air When Start The Vehicle
Having issues with the AC system turning on to blow cold air? The problem seems to be intermittent so I don't know how I would be able to replicate the problem if/when I take the car in for service. My problem typically occurs when I start the vehicle. The AC will be on but will blow warm air. I seem to have to continually play with the HVAC controls for it to finally kick on and blow cold air.
When I searched, I read that the malfunction may be caused by a bad solder in the system but wasn't able to find a concrete resolution to the problem. Should I call a few dealerships to see if the service writers are aware of the issue? Being in AZ, not having AC for the first 5-10 minutes in the car can be brutal. The car in question is a 2014 3.6 SEL ...
Elantra XD (2001-06) :: Heater Won't Blow Heat
2005 Elantra here with 120k miles
Problem: Not heat will come out unless
1) I don't turn on the Fan Motor at all. Very Nice heat will "bleed" out of the vents as long as there is no Fan on - on any setting.
2) Lukewarm heat will come out if I am giving the car gas or revving it. As soon as it goes back to idle or I am no longer giving gas it goes back to no heat at all.
Things I have tried:
Topped up the radiator and tank (radiator has been replaced)
Water pump replaced
No leaks
Thermostat is opening ( Upper hose gets hot, Lower hose stays cold for a while and then gets hot)
Flushed heater core with a garden hose.
Inlet hose to heater core is hotter than outlet hose but outlet hose is not cold to the touch.
Radiator cap has been replaced
Car does not run hot at all
Ford A/C :: 1997 E150 Heater Won't Blow Hot
I have a 97 E-150 with factory air (vin L) the heat/cool quit working just before summer it quit blowing cold. The old man took it to some mechanic (i hate when he does that) and he fixed it so there was air only saying he had a choice of cold or hot (being summer in the desert he chose cold). Now that it is cold and we are traveling where defrost is needed, I need heat!!! I went to the Ford dealer and picked up a new potentiometer and that did not fix the problem. whenever the unit is on the a/c compressor kicks on........ Is this electrical or vacuum and where might i find the problem?
