Ford F-150 (2004-2008) :: Noise Coming From Dash Around Radio / Heater Controls / Vents
Coming home from work tonight, Radio turned down, Air off/Heat off. Whats the sound coming from the dash around the radio/heater controls/ vents? Can't really explain the noise, but its like a boiling/clicking/scratching noise.

2001 F150 5.4 4wd - AC not working but when I turn the temperature dial to the blue side and turn on the fan, super hot air comes out of the vents or wherever I direct the fan to blow (Floor, defrost, etc) I know it shouldn't blow ice cold especially since my AC doesn't work but.....shouldn't I feel a temp change coming from the vents when I move temp dial from the red area to the blue? It's max heat wherever I have it set.

I have a 2008 F350 and there is nothing blowing out of the vents or defrost for AC or heat. It doesn't matter what fan speed is set. Would this indicate a blower motor? Where exactly is it located and how to change?

My 99 windstar has seemed to have issues every month since it's been paid off! Isn't that how it goes....anyway,
Just recently the heat suddenly stopped working. The fan is blowing and the temp controls seem to function correctly. There is no heat coming from the front and some IS coming from the back.
What could the problem be? Blend door, actuator, motor, evaporator core?
Ford A/C :: 1986 F250 - No Heat Coming Out Of Dash Vents?
I have a 86 f250 with rebuilt 302, new radiator, new hoses and heater core. I know the cold to hot selector works to open the door. now the ac works great although my heat is not working properly. I can put the defroster on with heat and the blower in the engine compartment comes on like normal. Now the problem is that we i put it on heat the blower in the cab does not blow air through any vents. I just purchased this vehicle and not really sure how everything works.
Funny thing also when the ac is on i turn the blower on low and its really high then the high is really low (its like to switch is working backwards) not sure if that has anything to do with it. Then when I was looking in the engine compartment i noticed the wiring harness has a plug going to the blower, then one plug to what looks like a heat strip of some sort, then someone took two oranges wires and wire nutted together to get the engine compartment blower to work. So now I'm wondering if I am missing something there??? Here's a pic of the engine compartment.......
Ford A/C :: Air Not Blowing Out Of Main Dash Vents
OK.. 2005 F150 Lariat. Air conditioner worked on the way to work, went to drive home, air not blowing out the 4 main dash vents. Blows cold out the feet, and redirect SEEMS to be working, just not blowing at all out the main vents in the dash?
Even if you adjust the temp to where it should be blowing warm/hot air, it will not blow out the main vents.
Prius (2004-09) :: No Heat / Vents Are Blowing Cold Air
I have an 06 Prius. I was driving my Prius today and I've noticed that my car has NO HOT AIR...
And this is Winter!! I was driving for about 20 mins and still...No Hot air...vents are blowing cold (cool) air.
I recently changed my condenser/radiator but I did NOT fill my condensor with the A/C gas yet. (could that be the problem?) But isn't the gas inside condenser is for A/C and not for the Hot air??
Any other stuff that I need to check to solve this problem?? (harness, fuse etc.?) It's cold outside and my car has NO HEAT!
Ford Excursion :: Air Blowing Hot Out Of Vents When Cool Outside
As the season has started to warm, I noticed when I have my air temp set to 60 and only using the vent and have not selected AC I have hot air coming out of my vents. After doing some research it appears that I may have a bad Air blend actuator, bad air door or something else. I took my truck to the dealer to get my fuel filter changed and asked if they could diagnose the hot air issue. Not being a mechanic I told the service mechanic the problem and he says the AC compressor always kicks in on fords even if the AC is not selected and maybe I have a leak and he seemed to think it more than likely was not the air blend actuator or blend door.
I told him I had no idea that the AC compressor always kicks in even with it not selected. I knew it kicked in for AC and for defrots but didn't think it did for anything else. He said since the 90's all fords did. Well I get a call that after diagnosing the system, they believe the freon is low. I just have my doubts and wonder now if I should've just tried to take the air door actuator off and test along with sticking something in the air blend door whole and verifying it was moving.
I was hoping someone that knows more than me can verify if the AC compressor kicks in even when it is not selected when I have the temp selector set to low 60 degrees. Does it make sense that I would have hot air blowing out of the vents with the temp set on low even when it is cool outside. All of my temp controls work moving from defrost, vent to heat as I can feel blowing out of the different zones.
Honda - Accord :: 2004 - No Hot Or Cold Air Blowing From Vents With Heat Or AC
Nothing will blow out from vents, with heat or AC. I checked the fuse under the hood and that had continuity, I checked the 7.5 fuse under the dash and that was fine. I also replaced the blower motor resistor and the blower motor with brand new ones. Also used a test light to make sure power was getting to the resistor and motor and that is all good.

Ford Excursion :: 2002 - A/C Blowing Air From Vents To Defrost?
My 02 V-10 Ex seems to be blowing Air from the front vents up to the Defrost unless it go through a series of events-- Hit Auto then forward Air then the fan has to be a 4 only. It will blow forward vents then go back and forth from theirr to the defrost. Also the Temp seems to be much hotter then it should.
Took a interstate trip this weekend though and it seems to blow much colder and do a little bit better staying in the front vents however still goes back and forth. Im in FL and its HOT!!!! The only thing I know is that its a vacuum system.. and that again its HOT in the truck as a daily driver.
Ford A/C :: Shifts Blowing Out Cold From Dash Vents To Lukewarm Air When Accelerate
My 2001 F250SD 5.4L is doing something odd. When I have the A/C on and accelerate, it shifts from blowing out cold air from dash vents and goes to blowing lukewarm air out from the defrost vents on top. As soon as I decelerate or tap the brake pedal, it switches back to the dash vents and blows cold again. Even minor acceleration switches the air from blowing out the dash vents to blowing out the defroster vents.

2002 - 7.3 lariat, my a/c stays on max because of the recirculating effect. When I get in the next morning during summer of course, my dash vents take a few seconds to begin, default defrost till that time passes. Sure I know about leaks and redone all that to make my vacuum hubs work correctly. It didn't begin till later not right after that overhaul.

My heater vents have been acting up. I have read that there may be a vacuum leak that causes the blend doors to default to defrost...
Where the vacuum line fails? I have ESOF 4x4 and that is still working. I think there may be a correlation between engine vacuum and my vents: at cruising or idle the vents work ok (not perfect) and under acceleration (less vacuum) the dash vents stop blowing.
I thought that the blend doors had their own vacuum pump, so I do not know why things change at different amount of throttle?
Town Car :: 2000 - Stuck Blowing Air Out Of Dash Down To Vents Or Floor
The town car will not switch its blower position from dash down to the vents or the floor. AC/Heat both work and the speed is still adjustable.
View 2 RepliesPrius (2004-09) :: Two Middle Vents In The Dash Stopped Blowing Suddenly
My car: 2008 Prius (base)
Here is the problem: All of a sudden the two middle vents in the dash stopped blowing. I have played with the settings - on, off, all the way hot, all the way cold - nothing from the two mid vents. The left and right vent blow with no problem. There is also cold air coming from the vent near the windshield - just the two middle dash vents are not functioning.
What I have done so far: I had it looked at by a mechanic who I trust. He said there is a small motor (he called it a servo motor) that controls that middle vents (open/close). He said that had gone bad. He manipulated it so that the air blows out of the vents now and said not to change any settings until I am ready to replace the part.
Jimmy :: 1999 - When Driving Its Blowing Cold Air Thru Dash Vents One Minute Then Super Hot The Next
I just replaced the blend door actuator. But now when I am driving its blowing cold air thru the dash vents one minute then super hot air the next. Also I had a problem installing the actuator over the keyed shaft on the housing...
View 1 RepliesFord Super Duty (1999-2016) :: 2003 Excursion - Dash Vents Not Working - Just Defrost
Air is only blowing through the defrost vents. No matter what I do - try to turn vents, A/C, heat, fresh air, recirculating, etc. Assume it's a switch or fuse issue somewhere. How to fix it?
View 11 RepliesFord - Explorer :: 2006 - Heater Controls / Air Does Not Blow Through Some Of The Vents
To kick off the coldest week (so far) of the winter season, I noticed a problem with the heater controls in my 06 Explorer with manual temp. controls. No matter which fan settings I select (defrost, panel+floor, etc), air does not blow through some of the vents. I can hear the fan working and air flows through the defrost vents and through the floor vents, but the there is no airflow through the vents below radio and round vents on the far left and far right sides of the dashboard.
Perhaps related to this problem, a couple months ago I replaced the blower motor resistor because fan speeds 1 and 2 did not work, only 3 and 4 worked, so whenever I would turn on the heat or A/C, it was on full blast all the time. After replacing the resistor, the issue was resolved and all of the speeds worked well. I guess I just never realized the issue with the vents, or maybe the problem happened because I replaced the resistor?
Since I'm not too knowledgeable with the climate control circuit, I'm not too sure where to begin, perhaps the switch or blower motor?
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?
