Ford - Explorer :: 2002 XLT - Heater Blowing Warm Air Instead Of Hot
Nov 30, 2015
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.

Ford F-150 - 1997-2003 :: 2000 F250 Cab Heater Blowing / No Warm Air
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?
Ford F-150 - 1997-2003 :: A/C Blowing Warm Air At 1500 - 2000 RPMs - Heater Core?
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 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?
Sonata I45 (LF 2015+) :: Vent Blowing Warm Air Always When AC And Heater Is Off
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..
Mercury :: 1952 - Vacuum Operated Heater / Air Blowing Out Is Not Warm
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).
Lexus GS 2006-11 :: Heater Blowing Cold At Idle, Warm When Revving / Driving
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!
Ford - Explorer :: 2002 - Ticking / Knocking Only After Warm Towards Rear Of Engine?
I have 02 Limited 4.6 with 128k and upon startup there's no noise (sometimes misfire, due to oil in plug wells, gonna change the intake mani and coils soon). Shortly after it warms up - 5 minutes or so there is a constant ticking at idle...I can't really tell if its there upon acceleration as I can't notice it with the window open when I'm driving, but as soon as I slow down and/or idle I hear it again.
If I let the car sit for a few hours, or while I'm at work, it starts up perfectly fine, no noise.
I tried the long screw driver trick - putting it to different parts of the engine and placing my ear over the handle, and didn't really notice anything different from any part of the engine. I had it up on my lift, and it almost sounded like it was coming from the rear - near the tranny, but what the hell would tick back there? and how do I diagnose that?
I dropped the oil pan when I first got it and there was a very little amount of black rubbery stuff - presuming its timing chain guide/tensioner related, but no chunks, not really any metallic shimmer in the oil, so I guess it could be that, I'm gonna pop the valve cover off and inspect - but like I said, didn't notice anything with the screwdriver trick....I'm at a loss
Ford - Explorer :: 2002 - AC System Low / Luke Warm Air Out Of Driver Side Vents
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...

View 3 RepliesFord - Explorer :: 2004 Explorer - Transmission Seal Blowing When Under A Heavy Load
I'm in a situation where I may be having to tow my 3500# boat/trailer with my '04 Explorer 4WD (this is well within the max tow limit, per the manual). I have the 4.0L with the 5 spd auto tranny and 3.73ls gears. I've towed the boat a handful of times with this vehicle and had a good experience every time. Now I'm looking at this being my primary towing vehicle, towing once or twice a month in the summer. The car only has 48000 miles on the ticker and is in pristine condition, so mechanically it's sound.
I asked my mechanic what he thought of this arrangement and he hates the Explorers, so he's giving a biased response. Have any of you towed something on a somewhat regular basis with this, or a similar, vehicle? Any issues? My mechanic keeps going on about the transmission seal blowing when under a heavy load.
Prius (Gen 2) :: A/C Blowing Warm And Middle Vents Not Blowing Any Air?
I've recently purchased a 2007 Prius and I just noticed few days go that A/C blows warm air (weather was fair when I bought it and I can't remember if it really worked or not then) and middle vents do not blow any air. I'm not sure if two problems are connected but I do want to get both fixed without spending $$$ at the dealership. Where can I start?
View 5 RepliesFord Excursion :: Heater Blows Warm Air But Not Hot
I've noticed that my X in the winter does not seem to warm up as it should. I watch the temperature gauge and notice that it barely gets to the first mark in the operating zone of the gauge. The heater blows warm air but not hot. I think its the thermostat that needs replaced because in other vehicles I would see the temp gauge rise and then drop when the thermostat opened. I've flushed the radiator and changed the fluid and not difference. I did find the heater valve on the right side was unhooked from the vacuum line and plugged it back in but no change from that being connected. Anything else I should check?
View 5 RepliesFord A/C :: 1997 F150 - Heater Only Blows Warm Air?
I have a 1997 ford f 150 lariat with the 4.6 v8 and my engine had a piston slap so I replaced the engine with a used one and I put a new water pump on the engine. My problem is the heater does not get hot and it only gets warm when I get on the freeway and the rpms stay steady for a bit. but when i idle it just blows cool air. the heat door works cause I can turn it to cold air when I'm on the freeway and i just replaced the thermostat so I don't believe its that. It weird because the heater worked fine before I changed out the engine so i cant figure it out. the only thing i can think of is the water pump is bad out of the box. Could it be the belt or does spacing on the water pump have something to do with it. nothing is leaking.
View 7 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...
Ford A/C :: Heater Blowing Cold Air
Heater is blowing cold air. What I have checked, coolant level, replaced water pump and thermostat, checked blend door, flushed heater core. When I checked the blend door via the heater treator method I was getting hot air coming off the core but also getting very cold air coming from the A/C evap in side the plenom box. I also pulled the fuse for the A/C clutch and I am still getting cold air. I am look at replacing the HVAC contol.

View 14 RepliesFord F-150 (2004-2008) :: A/C Blowing Randomly Warm Air
I'm having issues with my a/c blowing randomly warm air. At idle (stop lights, heavy traffic) the cold air will kick off but the fan will remain constant. Once I'm back up to full speed, the cold air will come back. It also works if I turn the a/c and fan off for a few minutes and turn it back when I'm at highway speed. I've recharged it and when it blows cold it will freeze me out. I'm thinking its a possible compressor issue?
