Ford F150 Vibrating, Humming AC - Blend Door fix 

Motors and mischief the GOAT love his channel.

I did that fix this weekend 4 Mar 2024. It took me about 4 1/2 hours, that I hope is the last time I do that . I did it by myself I had no help. Seems to be working fine. My arms looked worse than yours, my hands got beat up. Good video very entertaining.

As far as the motor goes… If the flap is closed it’s in recirculating mode. Plug up the motor, turn a/c power on, and select recirculating on the dash. The motor should move to the recirculating position. Turn power off. Line motor up with splines on blend door. Done. If you don’t time it correctly you may end up breaking the new part. The blend door will be in one position while the motor is trying to move it to another position not in relation to the switch/ blend door position. Hope that makes sense.

Thanks. I had the noise start yesterday on my 2014. It took me about 15 minutes to pull the fan and about an hour to get it back in. That last bolt was so hard to get started. Great video! I am not going to attempt the second half of that fix

Wow just got my gen 1 raptor 2days ago in Africa and had this issue after years of use States side with no issues with the winter and hot summers ...just right in time video King!

So after watching your video and @motors and mischiefs video was able to fix my 2013 f150 fx4s flapper. I wish I could have taken video of the process . Took about 3h and half total , taking apart was a pian in the a#$ . However it is possible to fix . Thanks to the both of ya'll for such great videos. No more cold air coming in from the bottom lol.

Love the make-shift raised work platform!!! Did this on my cousin’s truck… one of the most uncomfortable positions to be in!!!

Great explanation guy’s, 2 years ago I removed the broken part and chose to not do anything further, really have not noticed any issues not have the recirculating door working, after watching your video it would not be worth the extra effort for me to complete the repair. Thanks for the entertaining tutorial.

Thank you so much I feel like family. I really appreciate it that two by Four trick that helped my fat ass get the job done and yes, I cheated and used electrical tape to keep my swivel parts and screws together and made it happen. Thank you guys love from California.

Thanks just had mine to break . I've been wondering what that part was . It's 35 degrees here in Missouri so I'll wait until it starts getting warmer before I tackle it . Thanks again .

Thanks for the video and another view on Motors and Mischief's method. As for me, not if but when this finally breaks I'll remove dash so I can replace the blend door actuators since they too will eventually go out. Knock out a bunch of stuff at once. Unless as you said it requires discharging ac system.

Thanks guy for sharing, actually it happened to me & I just fixed the door to the closed position 😊 with a tie rap til I got the new part.

Just had to do this repair on my sons 2014 f150 . Need to be a three handed contortionist to get that blower motor in and out .Went ahead and put a new blower motor in so it should be good for another 100k miles hopefully.

Unplug the door motor once its set no need to let it flap back in forth and break again.

Sure as sh!t a few days ago my 2013 F-150 began making the exact same noise when I turned on the defroster on a 18 degree morning to thaw the frost off from the windshield and to warm the cab up. Needless to say when turned up on high speed the blower fan vibrates the hell out of the entire vehicle and you'd think that you're experiencing a blow out at 70 miles per hours. After watching several videos including this one I believed that I had the same issue and began the process of removing the cab blower fan which is conveniently located far and up under the glove box. For a fat, 67 year old guy with both knees and hips being replaced (a life of football as a center) it ain't easy to wedge yourself in to be able to feel let alone see the 5/16" hex screws that hold the blower fan in place. Thoughts of slowly strangling the Ford engineer(s) that designed this set up came to mind on several occasions as I attempted to remove the hex screws and most especially the back one which will require a 5/16" mini offset ratchet wrench given that there is no room to use a 1/4" drive ratchet and short socket. A 5/16" box end wrench will also work but will take you forever given that you can only get a very small turn on it. Once the blower fan was removed sure enough there was that little round piece of black plastic with a spline opening and the remnants of the rubber flap that it used to be connected to. After reinstalling the blower fan amid much cursing, plugging it in and turning it on I'm now back in business. Shame on Ford for building a decent overall product with some poorly performing parts such as the fresh air flapper connector which in my estimation should be the last thing to ever fail and double shame on the engineer(s) that designed this portion of it.

This just happened to me yesterday! If I just remove the peice that busted off it shouldn't shake anymore? I just won't be able to switch back and forth from recirculation?

now you know what its like to be a Porsche Mechanic.... I remember when we had those little actuator motors start binding and making clicking noises on the First Gen Cayennes... depending on the options for the A/c some of those damn things had like 12 actuator motors to be replaced.. under warranty no less.

Mine works, I live in Texas, but I don't need this hassle, since in max a/c with recirculation activated, can I just unplug the motor and it will stay in recirculation

Do you know the part number for the replacement assembly?

I screwed door shut, as i know here in Texas it will just break again, I never use outside air so...

Oh Gosh! This was something! I wonder if this happens for a reason or its just normal wear that can break it. On our 2010 Raptor we have not had this happened. Is it possible for it to happen on an old truck like that? Anyways Awesome video!!

188k miles on my 2012 and haven't had this problem yet... Hoping I never have to lol goodness that looks horrible.

If it doesn't have to be perfect, can you grind off some sides to let it slide in?????

I have this issue. I’m just going to close the existing flap manually and let it closed.

any one have a trick to get that back screw i cant seems to get it even with an elbow joint

Can I just tape or glue it close 😅

Can't believe how often this happens and always on the actuator side.

Never realized how many of my fellow travelers on the road were high on marijuana until this broke on my truck 😮

Litering and... 🤣🤣🤣

Same problem with my 2013 F150 in 2023. In my research, I've found numerous vids of people posting about this exact issue and all coming to the same conclusion. Some sort of keeper breaking off a recirculating door and ending up in the blower motor cage. No telling whether this failed part will manifest itself in other ways. Crappy design that probably should have been a recall but Ford doesn't have the integrity for that. I've driven Ford truck's all my adult life but this will be my last.

People at Ford are laughing knowing this would happen after the warranty is gone? 😉🪬🪬🪬
