Tech talk #3: 4 common causes of lack of air flow out dash vents

[@dinodank8862]

I have a 2008 Ram. No air flow thru the system. Everything checked out, but something was blocking the flow. I took the fan out and reached up inside to the evaporator. I could feel the crud covering it. My fingers had black sludge all over. Used a little brush to clean, but not good enough, so I took the wand part off of a garden sprayer and fished the handle up inside there to wash it out. Brush wash brush wash. Now I have good air flow! Thank you for the inspiration

[@HeatherHunterJ]

This totally 100% helped me this morning. Thank you very much!! I thought my AC was going out. Step 1 blower motor noises good. Step 2 check air filter - good luck finding it but once I did BOOM air at all speeds in all vents!! Thank You Thank You 🌟

​@@MotorCityMechanicI have a question man. I have an 87 brougham. The AC comes out at the bottom of the dash but no where else. There is a wire that is not hooked to anything and my thermostat doesn't let me change it. Is that wire supposed to go to that and if so where does it hook up at? Plus, do they make plug extensions if it will not reach?

Great video! I will say now my cabin air filter was worse than that. It was almost completely black/dark gray. No one has ever mentioned changing it. I've owned the car for 5 years and never changed it. Possibly previous owner of 3 years never did also. The ridges were so thick lol, the whole thing was heavy compared to the new one. Now I know to change it once a year. Unfortunately my dash vents were not blowing air out after changing it. I heard a loud clicking sound one day trying to defrost my dash window and im thinking the door broke because I heard It trying to change directions multiple times before it started to just blow out on the face/front vents.

Thanks for your expertise when it comes to MOPAR - and other vehicles that may have this problem. I've found a one year cycle for replacing my air cabin filter works. Other parts of the country may go more - or less, but this part is relatively inexpensive compared to a service call.

Thanks for the help! I was getting fan blow, but no air through the vents. It was the cabin filter. Almost stopped blowing immediately. Thanks for the video and advice !

[@outdoorztime2923]

Thank you, sir. That was very informative. I checked the blower motor (that is good), changed the cabin air filters (they were awful). After completing steps one and two, there is still no air flow from the dash vents, so I plan to take it to the shop for steps 3 and 4.

[@sithlordbok420]

Very good info to have! '13 Malibu, air only comes out the main cabin vents no matter which direction i try to set it at, except one setting blows it out the floor and main vent, but never the windsheild vent (I live in canada, so i need them for frost a lot). When i switch the direction setting, it does TRY to switch, the air does sound like it's slows to switch to the new setting, but then right back to mainly the cabin vent.

I just purchased a 2012 Nissan NV passenger van today from a private owner. The ac is cold but it does not blow hard. The fan increases speed and seems to be working good. Checked the blend doors and everything is working. The cabin filter is missing. The previous owners lived on a dirt road and a farm. There was so much dust and dirt all over the ac box and dash. Its gotta be a clogged evaporator. The rear ac fan is not working either. Gonna check it out tomorrow. Thanks for the video.

[@bobhunter3050]

The outside air filter is behind the glove box . There’s 2 White plastic pins that need to slide in order to remove glove box . This will be a hard challenge but they will slide . Now the filter door, it’s hard to release the 2 fasteners, can be done, of course all is plastic, be careful and stuck with it .

[@JILLYSDAD6]

Thank you. I have a 2010 Lincoln Town Car that is NOT equipped with a cabin air filter, but my 2001 Ford Taurus is (?!?!?!).I replaced everything, but the evaporator. The compressor went, and I picked up/installed a kit from Rockauto (Compressor/Condenser/Filter-dryer/Orifice tube), and replaced the high pressure hose, as the schrader valve was leaking on it. The A/C is nice and cold, but the dash airflow is not as good as it should be. The dash vents are working as they should, so that leaves the possibility of the Evaporator being clogged. I will check that in the next few days.

I just watched your Dodge Ram Diesel dash removal and realized that is a job for someone with a little more time and experience than I have, but I like to troubleshoot problems. I have a 2011 Dodge Ram 1500 and when I have the A/C on first two levels (Low & Low/Moderate) I barely get any airflow. But, when I switch it to the last two levels (Moderate/High & High) I get a brief blast of air for maybe 5 seconds at most and then it stops blowing as hard, but still considerably more than the bottom two levels. I thought maybe it might be the cabin air filter, but there wasn’t one (which I quickly remedied). I replaced the regular air filter as well just in case. Neither helped out the situation. I don’t hear any clicking sounds or anything that would suggest the recirculate door is broken. I noticed the part that moves up and down above the cabin air filter appears to be functioning. I wasn’t sure if there was another part there I wasn’t seeing that could be blocking the flow of air. Ideas besides a clogged condenser? It seems odd it would start off strong and fade within seconds. Thanks for putting out such solid content for hopeless handymen like myself.

I have a 2003 Silverado 1500 (6cyl), and now understand there is NO cabin filter because it has the mesh running along the dash under the hood. Parts stores AZ and o' Reily state there are. Wondering if I should check anyway by removing the screws under the glove compartment then pulling that black underneath panel off. Could there be 'cabin filters' from end of 2002 for the 03 model? Blower seems real good 1-5, air is cold after 21 years, but nearly all air comes out the defrost. Any advice please.... thanks steve

Hello I’m so glad I came across ur video. My situation. I have a 2014 Toyota Camry XLe. There seems to be no air flow coming out through the vents. I changed the cabin air filter because it was dirty. The air finally came out through the vents. Then when I turned the car off again it stopped. I kicked (hit) the area under the blower motor and it came back on. So everytime I start my car I need to hit that are and it turns on. Do I need to replace blower motor? Can’t be relying on hitting the area for it to start. Please help. With these heavy rains in cali I need my air flowing .

To me it sounds like the system is freezing up. That can be caused my multiple things. One would be if the system doesnt cycle off and on.....if it runs none stop it will eventually freeze up.

[@MotorCityMechanic]

Just making sure it wasnt typed wrong. You said the heat coming out the drivers side but less heat on the drivers side.....do you mean less heat on the "passenger" side? If so then the most likely cause will be the heater core being clogged. I have replaced a few of these just for that issue. Take a look at the coolant bottle and see if there is any "build up inside. There will most likely be some in the bottom. This can cause the heater core to clog and sometimes the radiator eventually.

[@feboogi]

sorry yes I meant passenger side has weak airflow and less heat than drivers side...can a clogged up heater core also affect airflow to one side? cheers

[@lextincteur]

I've got the same issue with a 2012 200 with the 3.6L.There are numerous complaints about no heat on the passenger side. The dealer fix is to replace the heater core, rad, and even the oil cooler. This requires removing the entire dash and even steering column. Is there anything I can do before committing to such an expensive repair, that doesn't seem to last anyway? Some report same symptoms just a few years later. It appears that it's either the HOAT coolant from 2011-2012, the OAT coolant from 2013, or both in combination with some other ingredient in the block or cooling system. No coolant has been added to this car, so mixing is out of the equation.

[@MotorCityMechanic]

@@lextincteur Typically alot of people only replace the heater core and not all the needed items. Then what clogged the heater core thats in the radiator and the rest of the system makes its way back to the heater core. You can try back flushing the heater core for now....take both hoses off. Using a waterhose with nozzle.....spray water into one of the heater core tubes where the hose went and keep swapping back and forth between both tubes. This may clear up enough to get the heater to work. Otherwise replacing all the items and performing a coolant flush is the correct fix. I havent seen one return personally for the same issue when it all was replaced.

I got a 2000 ford expedition I have no air flow so I straight wire the blower motor to the battery and its blows air but once I connect it back to a electronic box of some sort no air flow what so ever around the cab

Wish I could tell you Jose......I dont know anything about Fords except for the few videos I have done on my Mustang. I recommend checking with Fordtechmakuloco......he has a youtube channel as well and is the "Ford Guy". Thanks for watching this video and make sure to subscribe.

I have a 1985 Ford bronco xlt with weak airflow on both a/c and heater. i have nothing stuck in ducts and cant figure it out. door works fine. I have also noticed that when its cool outside the accumulator and lines are frozen. any ideas?

[@MotorCityMechanic]

Cant tell you much about a Ford.....99% of the videos I do are Chrysler related.

[@JoseSilva-yi6yl]

so i have a 2011 nissan titan the heater works good but i cant get it to blow air to the floor vents what do you think the problem is

[@adorabledeplorable5105]

I get small leaves in my dash vents on my 1990 ranger . I have looked everywhere for a “ filter “ and yet to find one . Any ideas ?

[@cgrobe21]

Not really common for trucks to have cabin air filters. Most do not. It's mainly cars.

[@adorabledeplorable5105]

@@cgrobe21 Thank you . But it still is a mystery how they get in there .

[@aldee3018]

just changed out my heater core ,thermostat and pcv valve but i'm not getting the same heat i used to. the air flow is strong just not as hot any idea what i can do to fix this issue?

[@deespasojevic3013]

Maybe air pockets in the coolant passages

[@FollowTheGoodShepherd]

Do you know where the air circulates from when the recirculating button is on? Also where is the air source coming from that is being filtered by the cabin filter? Is it in use only when it is on recirculating? I use my ram for hotshot hauling and I sleep over night in it and so air quality inside is important to me. My 3500 didn’t come with one but I’ll have to modify mine and add a filter which it’s easily done. Thank you for the video!

[@MotorCityMechanic]

Follow The Good Shepherd when recirc is on....the air enters the hvac box from behind the glove box. All air the enters the box in any position is filtered if there is a cabin filter installed.

[@rumoursduo]

I've got a weird problem: I turn the AC on with cabin dash vents on. All works fine. But when I accelerate up a hill, the AC stops blowing through those vents, & instead it blows onto the windscreen via the demist vents. I don't know what's wrong or how to fix it. Any ideas please?

[@MotorCityMechanic]

Sounds like you have an older vehicle that uses vacuum to control the hvac doors. Possible problems are a vacuum leak or the vacuum check valve is bad

[@rumoursduo]

@@MotorCityMechanic I would never have known that! You're right, the car is a 1998 model. I'll follow up on your suggestion, thanks.

[@nurseconklin7023]

We just replaced my blower motor and literally after turning the car back on...the air just comes out the defrost up top. All speeds work but pushing the dials (front, feet, etc) doesn't direct airflow to those areas. Resistor is fine, fuses don't look blown...help 😭😭🤦‍♀️🤦‍♀️

[@dakotatoby6194]

I have a 98 Jeep Cherokee sport 2dr my question is does it have a cab filter

[@MotorCityMechanic]

On that older model it does not. We really didnt start using them until about 4-5 years ago on some vehicles....some a bit longer. Thanks for asking and make sure to subscribe.

Well eplained it. Buen trabajo. pero sigo buscando algun video donde cambies el AC Compressor del 2005 Grand Cherokee.

I have a 1998 e150 not much air comming out the vents or floor doesn't matter if its ac or heat.motor is blowing put a new one in new switch and the resistor im thinking ac condenser to

Its very possible it could be a broken door inside the hvac box or evaporator blocked like in this video. Thanks for watching and make sure to subscribe.

Late 90's Ford F and E series heaters had a problem with the plastic blend door shaft breaking. I have fixed two of them on my two 97 F150's. Since I was replacing leaking heater cores I replaced the doors with the new upgraded doors that have steel reinforced shafts not the all plastic ones they came with. It is a VERY long job to do yourself and a dealer wants $1,200-1,500 to do the job. BUT there is a kit to fix it that saves 6-10 hours and you don't have to remove most of the dash. It requires you to remove the glove box, cut a small piece of plastic behind the glove box, then cut a section of the air box around the heater core to access the broken door. Then a two piece fix is inserted, one from the opening you made and the other from the actuator motor you remove from the bottom of the air box. Then you put the piece you cut out back and seal it with the foil HVAC tape that comes with the kit. It takes about 2 hours instead of 10-12 hours. Google 1997-98 heater blend door repair kit and search You Tube for videos on how to do it.

[@NoelKerns]

Would it be a fair statement on a 2002 Ford Explorer that if you don't see or hear any difference in the slightly weak airflow between outside air and recirculated, that the recirc door is likely broken and blocking?

[@MotorCityMechanic]

I am not familiar with that vehicle but based on what you said.....if no change with recirc then it could be a door or what ever controls that door.

I have a Ford Focus 2013 model, currently my standard vent won't flow good air but the floor, and window dash will flow fine. It does this mainly when its hot outside.

[@MotorCityMechanic]

I am not familiar with that vehicle but I dont think it will be the same issue. If you have different amounts of flow out of different vents that I would think there must be an issue with the hvac box.....either and actuator or possible broken door or something related along those lines. Thanks for asking and make sure to subscribe.

[@aguilamayor9354]

I have a 2017 ram 3500 dually and heater not blowing hot

[@MotorCityMechanic]

No heat could be an hvac door/actuator issue which isnt common on that year model.....the other thing is the coolant level could be low or have air in it.

Thank you for the video. My hyundai Santafe's ac (cool/heat) works fine. I have recently noticed that sometimes I can hear the fan responding to the fan speed knob normally but the air from vents is so weak and I hear like the air is being leaked somewhere inside above the glove box. My cabin filter is new and it makes no difference if I run the fan without a filter too. Can you please advice what could be the issue ?

[@MotorCityMechanic]

Sorry but I dont know anything about Hyundai......I am a 20 year Chrysler tech and its the only brand I know. Wish I could help but everything I would tell you would be a guess and that wont help you. Thanks for watching
