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 wife's '02 Explorer has developed an issue with the heat/AC. As far as I can tell, the heat is hot when it's supposed to be hot, and the AC is cold when it's supposed to be cold. But, the problem is that everything only blows out through the defrost vents, no matter what setting it is on.
I know there are other threads on this type of subject, and I have read a lot of them. I thought I had identified that actuator gizmo as the culprit, but the more I read, it didn't seem like the symptoms for that issue are exactly like mine. I want to try and fix it myself, and I'd love to take the time to read everything on the subject, but warmer weather is here and my wife wants it fixed yesterday!
This problem reminds me of the time the vacuum pump went out on my F-350 and the defrost vents were all that would work. I wish this problem would be as easy to fix as that was.
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.
View 14 RepliesI 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 RepliesI've had this 2012 SE I4 for about 6 months, but since it has been cold, I've noticed that when switching heat to floor vents only mode, that most of the air still flows through the upper vents (I'd estimate about 50% still flows through the upper vents).
I've taken a thermometer and read 80F coming out of top vent and about 60F coming out of the bottom.
When driving my face/body feel like they are on fire but feet still remain cold. Took to the dealer and they said there is a temp/and airflow difference but appears normal.
If this is normal, it is totally different than any other car I've owned. Does most of the air still come out of the upper vents when on floor vent only?
I've noticed today on my Camry that no matter what I set the air flow selector to on my heater, air only blows on the floor. Temperature and and fan speed seem to work fine. Going around to some local repair shops I was told the whole dash would need to be removed for a repair.
From what I have read changing the air flow selector I should hear some motor make the change from the floor to the face, but do not hear anything.
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. . . .
View 5 RepliesI have a 2002 Ford Taurus which I bought in the Winter and didn't check the air conditioner. It only blows hot air on any setting, some settings blow more hot air than others. I will have to pay to remove the dash to find out. Here's the weird part, last summer the coolant was a little low and I was stuck in a drive thru line. I watched the temperature go up until, lo and behold, the air conditioner kicked in and blew frigid air! It came on and worked twice more that day. I filled up the coolant and it hasn't worked since.

View 3 RepliesEither running A/C or heat.. air only blows on the '2' and '4' setting.. so I have middle of the road or WOT when it comes to the amount of air. On the '1' setting nothing comes out and '3' setting is the exact same at the '2' setting. What is going on with this.
View 3 RepliesOn my 06 GS300 135k my driver and passenger side blows different even though the temp setting is same. I have replaced Driver side Servo motor but no change. When heater setting is at 75, passenger side blows toasty, but driver side is cold. What else do I need to look at possibilities?

View 7 RepliesOn my 2000 f250 diesel, it seems like the ac blows barely on the max ac setting. I swear its gotten worse over the years. Is it the fan? something else?
View 3 RepliesMy 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.
View 9 RepliesI have a 2008 Ranger sport. When set on max a/c can only feel a small amount of air coming out of the vents. Compressor gets cold an condensates. Would this be a problem with the actuator not opening the damper all the way?
View 2 RepliesI have a 2007 Camry SE-V6 and recently noticed my heater is not working properly. The fan dial works fine and I can adjust the speed of the fan no problem. When I adjust from the defroster, to the feet, to the face etc.. I don't hear that noise I usually hear of the system opening or closing the appropriate vents in behind the dash - all I hear is the fan blower going - as though it's just blowing on my windshield but no air seems to be coming in any of the vents (ie. if I put the dial to the face and the fan speed on high, no air comes out the vents).
If I adjust the temperature, I can feel heat is there vs. cold but since no air is blowing out (all I hear is the blower fan going), I don't get any heat in the cabin. Is this a fuse problem or something more serious? I have about 70,000km so I'm out warranty of course....
I have 2002 1.8T Wagon GLS with a manual climatic (with 3 big dial buttons). The weather is now getting cold and yesterday I started to realize there is no air coming from the bottom vents (both passenger and driver side) when the air flow dial button is set to bottom vents. All other positions (windshield and front vents) are all working. The air flow dial button appears to be mechanically controlled.
View 1 Replies1994 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.
View 2 Replies2002 Echo, automatic, 190k miles, no troubles with it. My AC and Heat have always blown out the vents, regardless of the direction that I want them to come from. The dial that should send them through the vents, the dash, and at your feet doesn't really do that much to send the air anywhere except through the vents.
View 2 RepliesI have a 2001 Mercury Grand Marquis and the A/C will not blow out of the vents. It is blowing cold air, but will only blow from the floor and defrost.
View 3 RepliesI have an '08 350 with less than 82K miles. My problem is the AC. The vents on the passenger side blow out cool air and all the vents on the driver's side blow out hot air. Even the vents in the backseat, the left one blows hot air and the right one blows cool (my son informed me of this as I hadn't even checked). As you can imagine it's very uncomfortable driving around in this CA heat every day, especially since the driver side vent in the center cannot be completely closed. What could cause this?
