Volvo :: 2003 - Car Won't Blow Air Through The Vents
Sep 3, 2015
My 2003 S60 tried to make my life interesting yet again by refusing to blow air through the vents as normal. Only a little finds its way to the vents. The fan sounds good and strong, and the temperature is proper based on my setting. It's like it's stuck somewhere between the three settings for the direction of the fan (head, torso, and feet.) It usually works fine for a while, and then it's like a computer or flap gate get tired and gives up...
It may be relevant to know that this issue occurred around the same time my cluster started dying. I have since reflowed it and it is working as normal. Unfortunately, the climate control system is still angry.

I have a 2003 Jetta GLI. When i turn my a/c on some of the vents blow harder and colder than the others. Why that would be?

After some diag I got the A/C to blow out the front vents. There are million threads on this issue half of them are never figured out. This is the second time I have come across this problem so will make this really informative for those who have this problem. If you A/C blows to defrost, yes most of the time its going to be a vacuum leak issue.
Step 1) turnkey on engine off, stand by passenger fender and listen.. can you hear the pump running? If it is your pump isn’t dead.
Step 2) does the pump run for 30 seconds then shut off? You may not have a vacuum leak. If keep’s running for ever you have a leak. Inspect all lines, especially those going down to the hubs for cracks. Also inspect vacuum lines under passenger glovebox.
Step 3) can’t find a leak? Disconnect the line going to the ESOF solenoid and plug it, if you pump stops running then your ESOF solenoid has an internal leak. That was my problem 6 months ago, replaced ESOF, A/C blows normally.
Try This Second! So my AC isn't blowing through my front vents again.... (more diag)
AC not blowing through vents and can’t find a vacuum leak? Take off glove box door, turn AC control switch to floor/defrost/front vents, watch the metal arm connected to the side of the big black box move up and down into various positions. I noticed on mine the arm will go down in positions (floor or defrost) But it will not move up! Which needs to happen to switch to front vents. If I push the rod up by hand manually, the ac will blow through front vents, and stay blowing through front vents even after I let go. PIC of metal arm thing connected to diaphragm, which changes air flow by moving flap inside the big black box
I am guessing the Diaphragm is the issue? The truck will continue to blow from the front vents even when the truck is shut off and restarted, it will stop when I switch the ac to a different position, it will not return back to front vents.

Problem: About 10 minutes after driving, the heat starts to blow out of the upper vents when the a/c is on automatic. The heat comes out even if the outdoor temperature is mild (55 – 70 degrees Fahrenheit) and the cabin temperature is warm, which heats up the SUV quickly making it very uncomfortable. Turning the a/c off tends to somewhat solve the problem some of the time, however, occasionally hot air creeps through the vents even with the a/c off. The a/c often makes a gurgling sound whether it is on or off. I noticed today (2/3/12) that the back vents are not affected by the problem, so the very warm air is only coming from the front upper vents.

My vents don't blow hot air, even when I have the dial set to max heat. The air is only moderately warm. In the winter, one definitely needs to keep their coat on when traveling in my car. (It's a 2003 Passat V6.) The needle in the engine temperature gauge is vertical once I have been driving for 5 minutes, so I think the thermostat is OK. This morning it was 17 degrees; I'd sure like heat soon.

So today is the first hot day of the year here in Central PA. I jump in my car at lunch - turn on the A/C & it won't blow out of the top vents. Blowing like crazy on my feet - and freezing them - but won't blow through the dash vents! Worked fine last year - awesome in fact!! Actually cool air is trickling through the top vents - but not blowing like I know it should.

Abridged version: My fans won't blow any air out of the vents. If I spin the blower/fan motor that is behind the glove compartment, it'll work again. But the cycle repeats itself every time I turn the car on.

I purchased Hyundai Accent 2005 (Used car) recently. My Air Condition is having some problem. when I switch on the AC the air flow very low from the vents, even i put the fan speed is full (4) feels like fan switch is in low (1). The blower giving sound like it is giving air like more than full speed. fan speed selector switch working ok, because the speed of the air vary from the 1 to 4 positions. also i feel very low cooling in high speed also. i found one more problem that if i change the air flow switch to defrost level, the air flow is coming through the windshield defrost vents and the floor vents. if the switch selected to Floor-Defrost Level also the air coming through the both ways. What could the problem.

On 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?

So, I purchased a 2004 Subaru forester at the in of 2013, from a private seller. When I turn on the a/c the air is warm, I thought maybe the refrigerant so low, so I check the level and it is good, the a/c compressor clutch engages, but warm air still comes out of the vents. I am asking what else could cause the a/c to blow warm air?

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.

I have a 2014 Santa Fe and after about 2 hours on the highway the A/C freezes up and won't blow air through the vents. If I shut off the A/C and run just fresh air in about 10 minutes the volume returns, and I can once again turn on the A/C for another 2+ hours. I run the A/C on fresh air not recirculate.

Of the 4 vents that blow into the passenger's face in my jetta, only 1 really works. All other vents seem to work well (i.e., windshield defrost, footwell etc) but the ones that blow the heat/AC in your face seem to be affected. the one working vent is the driver's side of the 2 central vents (the ones above the stereo) neither of the 2 for the passenger work, and the one by the Driver's door works a bit.
I've tried opening them with the dial on the dash and closing, but that seems to have little effect. Are there dampers or something that can be adjusted on the inside of the vents?
I've spent some time searching on this one and I mostly found how to replace the heater-core and the blower itself. The blower works as does A/C, that one vent is ice-cold, but the other 3 don't really do anything.

I have a 1990 Chevy Celebrity wagon with a vent problem. The air will only blow out the dashboard vents, so I'm getting no heat down below, or air to the defroster.

I have an issue with my a/c. The left side blows out air but it is not cold. The right side is cold. The whole front dash has 4 vents total so the left two does not blow out cold air at all.

The climate control can be completely off (fan, everything)... and my vents will commonly continue to blow (room temp) air. Don't know if I'm missing something here. This is while in motion or stopped.

Cannot figure out how to get the heated air to flow through the back via the rear vents. All I get is outside air. I cannot find anything about it in the manual. The dealer has no clue but is trying to find something on it. New 2009 Santa Fe Limited.

I recently had my Focus in the shop for some body work due to hail damage. After I got the car back, the air vents on the dashboard and the defogger would not blow air. Only the lower vents would blow air, regardless of which setting I had the vent selector on. (Even if I had the selector to defogger or dashboard vents only, the vents by my feet blew out air). The guy who runs the body shop said that wouldn't be related to anything they did on the car. What might be causing this? It's no longer under warranty, so I want to know if there's an easy at-home fix. (Also, when I got the car back, the dashboard clock and the preset radio stations had been reset. Don't know if this might be related to the problem with the vents).

My 2004 Mazda3 is having an air conditioner issue. The driver side air vents blow hot air, but the passenger side air vents blow cool air (not as cool as I think it should be, just cooler than the hot side.) We had issues with it last summer that were repaired and freon was added at that time.

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?

2002 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.
