Weak Air Flow From Dash Vents - Common Causes

In this video I show you the common causes for weak and low Air Flow from your car or truck dashboard vents. Some of these causes are very easy to diagnose and fix. I talk about the dash vents, the fresh air vents, the cabin air filter, the blower motor, and the blower motor resistor. Watch this video to see the troubleshooting steps to find out why your heater and ac fan is not blowing strong air.

[@user-bn6zh1qy4y]

2008 Ranger. After removing dash(per diagnosis by Ford dealer)and finding nothing, finally decided to check fan rotation, and the fan was wired backwards. Swapped wires on plug and Sha-zam! Works great!

[@edwarddavis4091]

The blower motor was wired backwards???

[@user-bn6zh1qy4y]

Factory plug plugged into fan motor, looked at "plane of rotation" arrow and turned on fan. It was running backwards. Polarity was reversed. Just snipped the wires at the plug and reversed them.@@edwarddavis4091

Useful info thanks 👍

No problem babe

[@SatoriDance]

I have weak but cool air flow with air-conditioning and full flow when I run heat. I'll check everything you mentioned to be thorough but none of those sound like they would affect one and not the other. 🤔

[@harryschneider1760]

2007 accord ac works great..after about 2 hours of use the air flow stops blowing from all vents...motor is still running..i did install after market radio with dual ac controls..was wondering if radio is over heating or the cause of this issue

[@rhjr90]

Thank you buddy I heard a high pitched whistle and thought maybe the filter. Buttt the first 5 mins answered that 😂😅 had the vents closed 🤦‍♂️ thank you !

[@hashim_attili]

Hi tbx for the video i have a qwq Q if i buy a biger blow motor and can be fix to ky car is that better air flow coming? Or i will get problem soon?

[@MattGoodfellow]

What about if you're changing from defrost, to dash air, to floor air, etc. Found ours doesn't seem to function, and we're getting weak airflow. I assumed the motor was an issue, but didn't see that in this vid.

[@kbuen0]

Just learned the hard way if you run the fan on high through the car wash it sucks humidity dampness into air filter and materials in air filter expand turn it blue and plug the air flow even after it's dried out it is ruined. Brand new air filters are normally white. probably that's why they turn blue when that stuff expands and filter is ruined. $20 AutoZone. I have 2008 Toyota Camry maybe more prone than other vehicles. Around the fan on high in my 2019 Honda Odyssey and that does not happen. But I won't temp fate anymore.

[@Samir-2]

What if there is a hole in the hose from the blower motor to the dash vent-box, can that cause a weak air-flow?

[@NSFDarkIce]

Not sure, this is a 2006 Toyota Corolla, right?

[@scu-dub]

Whats causing only vent to work and feet I can't get windshield to work and driver side only blows warm on 34 setting it 12 it blows cold like passenger side does whats the issue any help!!!!!!

[@refills9344]

I have a 1999 camry, doesn’t have a cabin air filter but I’m having a problem where I put the fan on high it works fine on the driver side but passenger feels like it’s on low. Any idea what could be causing this ?

[@singh-zq9mh]

Hello did you find any help what was the issue . I am having same issue

[@infinity3jif]

The 2 passenger side vents are blowing strong but the 2 driver side vents are weak. 08 Crown Vic

[@user-ui8zp4tl4o]

Hey real quick, sorry to bother you. But that was a 2011 Nissan Armada correct? 😂 I’m sorry, it’s all in fun.

[@mackbang]

I wonder what car that is?

[@myyoutubepage199]

what about if its cold as F when u drive but when you idle it still blows cold but not as hard as when you drive? no one talks about that one

[@AZHighlandHomestead]

Sounds like your battery might be going bad

[@myyoutubepage199]

@@AZHighlandHomestead battery? its new , I took out the cabin air filter, now it blows hard but not ice cold like it does when you drive . Just passable cold. I wish it would stay the same cause its 110F here.

[@AZHighlandHomestead]

@@myyoutubepage199 check your a/c compressor or alternator belt tension then. Sounds like it could potentially be just a tad loose. It’s

[@myyoutubepage199]

@@AZHighlandHomestead might be the belt cause i think the ac would not blow as hard if i were driving, well not the hard blowing, i mean the ice cold blowing, Yeah cause it feels like an icebox inside, when idling 3min it feels like its throwing air maybe the same speed now after changing cabin filter but not icy cold, just cold and you start feeling the heat from the windows and roof , once driving its back to an icebox .lol

[@AZHighlandHomestead]

@@myyoutubepage199 I hope you get it working better soon. I’m in Arizona so I know how critical it is to have good AC

[@mamajhons4817]

Well I feel stupid I had my vents closed I thought it adjusted the tilt
