Ford F-150 (2009-2014) :: AC Blows Through Floor And Defrost Vents Only
I have a 2010 f-150. Started having issues with the blend door actuator located behind the radio so replaced that a couple months ago and fixed issue. Now the a/c will only blow through the defrost and floor vents. I replaced the lower blend door actuator thinking that might be the culprit, but did not fix the problem. What the solution might be.
View 3 RepliesFord A/C :: 2007 F350 - Vents Work Up Top But Not Forward Or Floor
I have this issue on my 07 F350 TD. The vents were working fine, then from one day to the other the following started happening. No matter which blower setting I select, air only comes out of the defogger vents on top of the dash. The forward and floor vents do not operate. Cold and warm settings work, along with all blower speeds.
Found this, but need a little more to fix it:
Problem: Air flow has defaulted to the defrost vents (either all the time or under acceleration).
Solution: The system is designed to default to the defroster in the event airflow control is lost. Intake manifold vacuum is supplied to the control head, whether manual or automatic (electronic) to operate the vacuum motors.. A very common failure is a split, cracked, or otherwise leaking vacuum line located between the battery and firewall. Other causes include a leaking vacuum reservoir (inside the right front fender), faulty check-valve inside the dash, or other vacuum leak in the system.
Ford Ranger / B-Series :: 2008 - Foul Smell From Floor Vents?
in my 2008 ford Ranger Sport with a V6. The smell reminds me of one winter when I had stepped in dog and didn't know it until I was four miles down the road and the heater was on full blast. The smell floods the cabin when the heater is first turned on and warms up, but dissipates after a while. (And I don't have dog on the floor boards or on my boots.)
The smell does not come out the AC vents or when the AC was operated this past summer.
Ford 6.7L Power Stroke Diesel :: Windshield Defrost And Floor Vents Won't Work
No matter what I do with the settings for my heater in my lariat air only blows out of the dash vents. Defrost and floor vents don't work it still blows hot air out of the dash vents. I'm not sure what the deal is maybe the vacuum system? I did a search and all I could find was people having trouble with air ONLY blowing out of the defroster and my case is just the opposite.

1998 F150 XLT 4.6l automatic,,,
Drove the truck on a trip the other day, about 650 miles with a loaded 5x8 trailer in tow. A/C started acting weird. When the truck was on level ground, or going down hill, the A/C was fine. Cold air coming out the correct dash vents. As soon as I started up hill, or put the truck under strain of acceleration, the A/C would stop blowing out the dash vents and would start coming out the floor or defrost vents, or just not come out anywhere.
When I turned the A/C off and just used the vent setting, it would do the same thing with the fresh air. I guessing this has something to do with my vacuum lines, somewhere. What I should be looking for and where?
Ford A/C :: 1997 E350 - Hot Air Blowing Out Of Rear Floor Vents / Blend Door Won't Function
My 97 e350 club wagon is doing something weird. Front AC wont go to Max Air, the blend door wont function. Can hear vacuum trying to work. Rear Unit is on Heat even though Front is on AC and blows hot air out the rear floor vents. Hit some high water going too fast about a year ago. Next day, this started happening. Rigged up blend door so air flows through vents.

The floor and defrost vents work. It just stays on defrost when you try to use the dash vents. The actuator seems to be working fine. I can watch the arm move through all the motions. and I cant find ANY vacuum leaks. Yes I looked at the hubs and under the hood. May be moving to alaska and kind of need my heater to work properly. . . .

Have a 02 with climatronic. You put it on vent and it blows out the vent. You press floor and it goes ape and the fan goes to max and nothing comes out the vents and nothing comes out the floor. IF you put it on floor only there is flow like normal. You can not have it on floor and vent. I drove 2 other passats and they both allow floor and vent. Havent been able to check codes because car has been at dealer for a week.

I have a 98 gtp 2 door with the electronic dual zone climate control. I can't get air to blow much out of the floor vents. I applied vacuum directly to the actuator and air came from the vents fine. It seems there is a box behind the glove box that controls the vacuum to each actuator. My question is, would the issue likely be with that vacuum distribution box or with the electronic climate box itself.

Would the control on dash cause there to be no air coming out heater vents on floor. I can hear the blower very loudly in dash about in the middle air comes out dash vents and out defroster ducts. When you switch to heater you get blower noise but very little air coming out floor vents.is it the control or possibly a vacuum mother on a vent somewhere

I turn it up on any fan speed, and set it on the floor setting, and nothing blows out the bottom vents. pretty much no air is getting to the bottom vents.
I do feel some air blowing out of the windshield defroster vents when I put it on the floor setting. seems like something is blocking it maybe?

My dad just got a 2012 Camry LE, with the 4 cylinder engine. The heater seems to be working fine except for the floor vents. When I select that option on the HVAC control, I can hear the fan working but there's absolutely no airflow coming out from under the dash.

The front a/c on my ex on the highest blower motor speed blows out the vents like its on low, but I can hear the motor blowing at full speed. It's not blowing out of defrost or floor unless I switch it. On lower settings I can barely feel any air at all. Only does this rarely. Could it be my vacuum pump?
View 4 RepliesFord 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.
Ford Excursion :: Smell From Vents Intermittently?
Been noticing this lately. Kinda smells like coolant I think but it's intermittent and for a short period of time. Notice it more when turning the heater on or when setting the temp to a higher setting.
Havent noticed any leaks on the carpet. Heater core? Why intermittent?

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 Excursion :: Electrical Smell Coming From Vents
I have an electrical odor coming from my vents. I always smell it when I start the vehicle. Other then that its not continuous just intermittent. I did have the passengers side front running board light short out and have since cut it off until its warmer to replace it. I wrapped it in electrical tape and stuck it back in the running board. I did have the odor when the fuse was burn out for the running board light. I replaced the pressure switch for the cruse control last year. I was thinking the blower might be going bad. What it may be?
