Ford F-150 - 1997-2003 :: No Heat / Blows Cold Air No Matter What Setting At HVAC Controller?
My brother-in-law has a 97 F-150 with 4.6L that has no heat in the cab (blows cold air no matter what setting at HVAC controller). Heater core was replaced one year ago and T-stat was replaced last night. Coolant level is full and the heater hoses are BOTH hot so I believe warm coolant is flowing through the heater core. I am thinking that the HVAC controller may be at fault or maybe the mixing door in the HVAC plenum is malfunctioning. I have 97 rangers that had a broken hinge pin for the mixing door inside the plenum (a common problem with these trucks), maybe this is the same issue (I don't know). I am taking the whole dash out to see what the trouble is.

1994 f150. When i use the max a/c setting, sometimes after a few minutes I hear a little thud and then all the air starts coming out of the defrost vents. This doesn't happen when using the regular a/c setting.

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 :: 2003 - Air Blows From Dash Vents Then From Defrost In Cycle?
My nav. when I put the air cond on auto and lower the temp so the air comes on, it blows out the vents on the front of the dash like it should and is cold. Then after about 30 seconds give or take, I hear a door deep inside the dash shut, or open, then the cold air only comes out the dash vents that are the defrosters for the windshield.
Then I can make it go back to the front vents again by pushing the button on the heater control to make the cold air come out the front vents again, but then it does the same thing again. Whats going to need to be replaced/repaired?
Ford Excursion :: AC Climate Control System / Air Only Blows Out Of The Defrost Vents
So in the past week only on certain days I have lost my ability to change zones for where my nice refreshing cold air blows on me from. It only blows out of the defrost vents. I here a fluttering noise under the dash when this happens. Also under the hood where all the AC hoses and such are located I feel cold air coming from inside the black box just next to what looks like the blower fan assembly. I don't believe I should be feeling that.

My 01 ac has worked just fine up until today. I got in this morning to leave the house and the air was only coming out of the defrost vents. I tried playing with the controls to get it to switch but couldn't. I assume its a vacuum leak, but where do I need to start looking?
View 14 RepliesCamry :: AC Floor Setting Not Working - No Air Blows Out From Bottom Vents
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?
Ford - Mountaineer :: 2002 - AC And Heater Air Comes Out Of Defrost Vents
On my new to me 02 Mountaineer, the a/c and heater air on my climate control system is acting up. Everything is working as it should, except that when you direct air to the floor, the air comes out the defrost vents. I took the glove box out and when looking from the passenger floor towards the center, I can see 2 actuators that seem to be working. I was wondering if there were more than 2 of them, maybe one on the drivers side that I am not seeing, Didn't know that if maybe when one closed that another one would open elsewhere. As I said everything else is working as it should. Also the recirculation door is working as it should. Something else that I noticed is that the top port(#6) on the row of the vacuum hose plug does not have a line on it. Where I can get a diagram or picture of the hvac system.

I've got a couple different problems. The first one is that no matter what setting I have it on, air only blows out of the defrost vent.. Why this is happening? or is there already a thread about this? i saw a thread for this same problem, but it was for 2nd gen explorers.
The second problem I have is that there always seems to be air blowing from some where on the passenger side, unless i am accelerating. I can't seem to find where it is coming from but it makes a really annoying noise.
It is the 4.6L, AWD. not sure if that matters or not though.
Ford Excursion :: AC / Heater Switches From Vents To Defrost When Blower Is On
When the blower is on, it automatically switches from vents to defrost vents on its on. Does it about every 4 minutes.... like it's haunted. Curious if this is something i can tackle or do i need to take it in...

2006 F250 with the dash controlled 4x4. I typically keep the front hubs locked on this truck. I have recently noticed that when shifting into 4x4 that the a/c or heat will switch from blowing out of the vents to blowing out of the defrosters. Any clues how to fix this?
View 1 RepliesJeep - Grandcherokee :: 2003 - A/C And Heater Control Panel Switch Is Stuck In The Windshield Defrost Setting
I have a 2003 Jeep Grand Cherokee with about 240000 miles on the clock. Words cannot describe how impressed I am by this car. However, yesterday I noticed that the selector switch where one chooses to direct the air output has failed me. It seems to be stuck in the windshield defrost setting, unable to redirect the airflow to anywhere else. I am however still able to control the temperature as well as A/C settings. The switch felt strangely 'limp' almost as though it is no longer connected to whatever engineering or witchcraft it is attached to behind the control panel. What are your thoughts on this? Could it be as simple as some mechanical linkage that has snapped off? Just to recap: blower motor, heat and A/C are not affected by this.

My 95 explorer heater only blows out cold air. I have topped off the antifreeze and just replaced the thermostat. The engine operating temperature is very cold, it won't even come up to the first mark. It is very cold here in Utah but I still can't imagine why the engine won't heat up.
View 9 RepliesFord A/C :: 1990 E250 - Heat Does Not Blow No Matter What Setting Low Or High
I have a 1990 E250 and the heat does not blow. I have only had the van a year and it somewhat worked when I got it, but at the end of least winter It stopped blowing. It does not matter what setting I have it on low or high. if I turn the defrost on and put my hand on the dash I can feel warm air but it does not blow. It is the same for the vent, I can feel warm air coming out but does not blow. Sometimes if I hit a bump it seems like it will blow a bit harder but not like it should. My question is, should I just replace the blower motor, or is there something else I should check first?
View 4 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?
Caravan/Voyager :: 2002 - No Matter The Temperature Setting AC Blow Very Hot Air
Got a 2002 Grand Voyager (as we name it in Europe), 3,3 AWD, with AC/Heating problems.
No matter the temperature setting, from 15C to 29, it will blow with same very hot air. AC working when setting the temp to LO.
Going from LO to 15 deg C, you'll hear a "clunk", as if a door closes, and the warm air will start to flow through the vents.
Tried all the calibration possibilities known to me (ON+Recirc), and it will end with no faults, but to no good effect on the problem.
What the "ON+AC" mode does? Been in that mode - but do not know what it does, or if I'm supposed to do anything.
I haven't got a clue, other than the "thump" I hear when, possibly, the blend door closes, might be a problem, since I would expect the blend to be more gradually invoked.
Ford A/C :: Panel Vents Won't Work / Defrost Vents Push The Air Out
I recently found out that my check valve needs replacing for my a/c vacuum. The problem came from when I turn my AC on, the panel vents do not work. Instead, the Defrost vents push the AC air out. How to replace the vacuum check valve? I would like to avoid the high cost of dealership prices.
