If you're having issues with fan noise, low AC fan air flow, or major vibrations in your dashboard/center console when you increase the fan speed, this video is for you. Chances are that these are issues related to a dirty blower motor that is clogged up. I go over how to remove the paneling to locate your blower motor. Before replacing your blower motor, clean it out very well and see if it solves any of these issues you are having.
The process is not difficult but will require the proper tools which I go over in the video. Hopefully this helps you out as there was very little online as to what the issues I was having could be.

• How to Fix BMW Blower ...
You're still helping folks! Thanks very much for the video. With your instruction, it took me exactly 45 minutes including the at-speed 2 mile test drive after it was all done. For those of you that come after, both of those bolts are 10mm. One socket and one 10 mm open wrench will do the trick. The second one just requires patience. The culprit in my 2013 328i was a single ficus leaf. But that single ficus leaf made the A/C sound like my dash was going to vibrate off. Thanks Leverage!
You're welcome. I'm glad it helped you. Its so crazy how those leaves get in there and create that scary vibration!
That second bolt is not so bad to remove. But even with the correct (stubby) open-end wrench, it’s a royal bitch to put back in. Getting the thread started is almost impossible!
Thank you! I followed your example today and only got a few leaves out but it made all the difference. I’ve been riding around with this annoyance since before you posted this video and always thought I had to change the fan at some point. I hope you have a metric set of sockets and wrenches by now. Good job!
Awesome. I'm glad you got it taken care of!
Great video. I had one leaf in the blower.... one flipping leaf. Got in and out in 30 minutes.
Hahaha 1 leaf. That's great. Glad it helped!
LeverageLifestyle that made a hell of a ruckus.
Thank you. Your video help me locate my problem too. I found what appears to be toilet paper, plastic wrappers and leaves. Puzzled how they made it past two filters.
Glad the video helped! Yeah, it doesn't quite make sense.
The video is very useful as I had no idea how to access the fan easily. Surprising that you had so much rubbish inside. The fan seem to take the air from the car inside, not from the outside. in my car the cause was a parking ticket which slipped through the space between dasgboard and the windscreen. The whole procedure is super simple, even taking out the 'difficult' screw was easy, but putting it back, was close to impossible. I did not have patience, and simply put tie-wrap instead.
Great Video! My AC is doing fine. I was going to clean this area. Later I found out my 2014 model had this section improved, it had a metal honeycomb filter built into it.
My 2013 has the same mesh you talk about, and when I got the dreaded “blower growl” I removed the blower/squirrel cage via the passenger side footwell, and found a Zig Zag rolling paper inside the squirrel cage.
Weird!
You are my savior. Incredible video. For your info, those 2 bolts you mentioned are the same, 10mm. You need a 10mm socket with extension and a 10mm wrench. My blower fan ended up having 3 baby creatures of some sort. Not sure what they are, but the car works great now. Huge Thanks and Great Video.
I'm glad the video helped you! Yeah some time after I fixed it, I started to see signs of a rodent and I wonder if that's how the leaves got into that area. So it's possible that it's the same in your case. Usually it will be either rats or squirrels so I would check to make sure you don't have chewed cables because I had both cables running to the door handles in the sideskirts chewed and cowl panel with chew marks and I just noticed a few days ago the insulation foam pad under the engine cover is chewed up and the valvetronic harness is chewed with one of the wires inside split as well which I never noticed. I'm going to buy peppermint spray and spray it under the hood which apparently repels them. I would do the same if I were you! Glad it's running like normal!!
Thanks for making this! I’ve been able to sort the issue without having to pay a dealer.
Glad I could help!
No wonder BMW wanted to do this for my 13' 328i, easy fix for easy cash.
I checked the blower motor on my one series just now and there was a big o ring of some sort in there shredded about 12" long and now the blower motor sounds just fine!Thanks dude!
I think it might have come off from somewhere as I had a shredded black material as well and have read about that happening to other people. Glad you got it sorted out
It should be behind the globe box. Ty for your video, Im about to do this.
@@uneverknw I actually had to do it again about 2 weeks ago. Hadn't done it since this video. Just a few palm tree seeds got in and would slow the flow of air and even stopped it fully. It's a quick, straightforward fix as long as you have the right wrench for the horizontal screw since it's difficult to access. I believe it was a 10mm wrench. Let me know if you have questions.
Thanks man! If it weren’t for you I wouldn’t have fixed the vibrations on mine!
Glad I could help!!
You had a bird make nest while on vacation bro, thanks for vid haha
Thanks man! Saved me from buying a new blower motor 😂
Glad I could help!!
Seems like this is my problem. Gonna have to clean mine and see if that helps. Good video!
Let me know if that works for you!
Don’t do this. I just did mine and it is much easier to go in from the glove box side where you replace the filter. The bolt to get the piece off from this side is a pain in the ass
Nice video. But you did not show how to put it back together. That one part that covers the blower with the hard to loosen bolt is impossible to get back in.
Thank you so much for the instructon. I worried also about the same. Thanks
Thanks for the video! Very helpful for my 2018 F30.
Awesome. Glad it helped!
Thank you so much!! Fixed my problem 😌
Awesome. I'm happy it helped!
Good video, I had a similar problem, Thanks for walking me through the steps.
Steve Hunt Glad it was helpful!
Definitely under the glove
Thank you. Very informative.
I'm glad it helped you!
The blower motor intake cover has two bolts. One on the left side, facing the firewall. The other is on the right side, and the head of the bolt is facing the driver's side. The clearance on that bolt does not allow enough room for a ratchet, so I had to use an open ended 10mm wrench, and even then, you can only back it out one quarter turn at a time due to the lack of clearance. This one bolt took more time to remove than for everything else. So be aware. This is a very simple maintenance procedure with the exception of that bolt. You've been warned.
Hahaha. Yep. I mentioned it in the video. It took me an hour to remove it because I didn't have a set of wrenches but with the right wrench, it shouldn't take more than a few minutes.
Time for me to buy some ratcheting open ended wrenches
This fixed mine thanks alot
Awesome tutorial
I didn't have to take that difficult screw of. When you loosen the other bolt there is enough room te put your hand in.
3 tiny leaves were enough to make a loud noise.
Hi, I am having same issue on BMW 320i 2006. Trying to find a video demonstrating the similar procedure for 320i but have not been able to find one. Any help would be appreciated. Thanks
Nice
Awesome video,
video was good but mine had a screen protect in it but still helpful
Does F20 has the same setup which will be needed to clean from time to time?
Your issue with the hard to reach nut is easy. This is an european car and they use the metric system. Use a 10mm spanner or wrench and it will be easy to take off.
Okay, my project e46, my dads old e91 and his new f31, and my f31 and even my moms f21 this intake is clear, not a single leaf or something in it. Wheres your intake filters?!?!
But isn’t the fan motor in the glove box ?
Isn't the blower accessible under the glove box?
Yeah, I found out after the fact. I never had to change it though.
Welcome to owning a 3 series! Where blower motor fans and crankshaft sensors are just the beginning of your adventures at the mechanic 🔧
Luckily I haven't had too many issues specific to it being a BMW, just normal maintenance outside of the sticky door handles I replaced and a leak in the window washer fluid hose after using the green rainx washer fluid.
Did your AC start blowing hot?
Believe it or not, removing the blower motor (from the inside, beneath the glove box) is far simpler than this exterior access at the base of the windshield. Both may need to be done, though.
Clean out the exterior intake AND remove leaves from inside the blower motor/squirrel cage. Yes… it’s hard to believe that leaves CAN make it all the way into the squirrel cage.
Yeah it turns out I think it was rats. When I removed the filter inside rat crap and leaves fell out and after I window screened the blower motor under the hood, I came back a few weeks later and saw it was chewed up. Smh. Probably cause it was cold out. I wiped em out though.
Is this just an easier way to access the area you'd get to by removing the blower motor from the footwell?
Yes… but… you might need to clear debris from BOTH directions. I did.
bruh! that is crazy!
Seems like you are missing a cover piece. My rotor had a plastic cover that can only be removed from the inside. (Has the size of the white rubber where you mesh window screen is placed)
I have a question. I have a 2011 bmw 535i and the fan is not spinning do u think i have the same problem as you?
Hey, it would depend. If you open up the compartment like I show in the video and there is a lot of junk in there that could be preventing the fan from spinning, it is very likely that could be the case. Do you have strong vibrations when you turn up the fan on high? If not, then it might be the blower motor itself or a part of it that's not working and it might need to be replaced by accessing it under the glove compartment.
Hi what kind of tool did you use to remove the panel closest to the windshield? The circular looking bolts?
Any kind of pliers will do. They are not tight, they only turn 180 degrees. Super easy.
Or a flat head works, just slightly pop it out from the side
@@leveragelifestyle8581 you should be able to open your trunk with the battery disconnected, theres a button on your key hit it and its an actual key that pops out, the bmw symbol on the back of your trunk flips at a angle if you press it and you should be able to unlock and lock it manually
@@ogmike8219 hey, I did realize after I had said it that I do have a backup key. Thanks for the posting the tip!
HEX head, quarter-turn toggles. The hole appears to be round, but inside is a hex head. I forget what size… just try the biggest one that will fit without forcing it.
So you didn’t play a clip of the sound it was making?
No, I got the idea to record a video when I was going to put everything back together. It wasn't just a sound though, it was a very very strong mechanical vibration in the center console and dash.
LeverageLifestyle oh ok cause my f30 is making a strange sound and I can’t figure out what it could be. It only does it once in a while and sounds like it’s between the engine and tranny but on the top side of it. That’s where the sound led me at least. Put it out the ramps and crawled under and it was coming from above so I was thinking maybe this could be the same problem but you can only hear the noise from outside the vehicle maybe very very faintly from inside when everything is quiet but soon as you open the door damn is it loud...
@@huckilt Is it when you turn up the AC? The sound and vibration I talk about in the video only appears when you turn up the fan on the AC. When it was off, it wouldn't do it. That would help determine if it has anything to do with the blower motor/AC. Hopefully it has nothing to do with it but maybe oil pump assembly or timing chain. You mentioned F30 which is what I have. I didn't have a noise but people have said sometimes when the chain is going out it makes noise (it can fail without making noise - mine was failing with no noise and I replaced timing chain). Either way, look into the timing chain because it's an issue with the N20 engines made between 2012 and 2014 if yours falls between those years.
LeverageLifestyle I have the n55 I’m pretty sure it’s prolly not the blower motor cause it does it at random on its own without me changing anything. The heat comes on when I start and it usually don’t start making noise for about ten fifteen mins after I start it. I can shut it off and start it back up and sometimes it will stay making the noise other times it stops. It’s so strange of a sound too I have a video I recorded of it. Trying to figure out how to post it here
@@huckilt Ah okay, good. The N55 is clear of that issue. Maybe post in a BMW FB group. I'm in a few groups myself and people can help diagnose the issue if you upload a video of the sound.
I also Have Vibration Only when Ac Is On And High Fan, I would like to try to Remove whole filter and blower as well, but im afraid to remove The negative terminal wouldnt it cause Problems ? Like these cars has Battery that registered to the Car , And would my settings get loose like Radio stations, seats setting all that?
Those settings are saved on your keyfobs. Each one has its own settings. I think the only thing I had to change was the clock.
LeverageLifestyle this weekend i will try to do the same u did, will update if it works or not but mine is same at higher fan its vibrating i thought first the engine idles harsh but no thats stable ,so it must be the ac
LeverageLifestyle by the way if u type in Newtis there u can find manual for every bmw How to fix etc..
👍👍
Don’t do this. I just did mine and it is much easier to go in from the glove box side where you replace the filter. The bolt to get the piece off from this side is a pain in the ass
I have the same problem now. Do you have a video or instruction how to get the glovebox out?
Nash year make n model
@@FiveEchodon’t remove the glove box. Just remove the two 10mm screws holding the lower footwell panel, then carefully disengage hidden panel clips by pulling the panel gently downward and toward the seat.
How the hell do the leaves get there if its covered with plastic all around
Haha I have no idea. I was surprised myself.
That is the mystery that stumps is all!
the fan motor comes out from inside of the vehicle not out side
Yeah, I noticed that when I changed the air filter lol. I'm sure if I had tried to get it out it would have hit me but I was just looking to clean the fan. Good thing I didn't have to take it out though.
Hey, i did this to my blower motor, but it was clean. My car still vibrates in the cemter console. Do you know what it could be?
I wish I did in your case. Are you getting the vibration when you turn the fan up high?
LeverageLifestyle when i turn the ac on i could hear it rattle and sometimes it vibrates in the midlle. As soon as i turn the ac off everything is fine
The vibration happens randomly when the ac is on at any level
Hmmm, it may be the blower motor itself if it only happens when the AC is on. I would remove it and clean it all out in addition to your air filter if you haven't in a long time. The blower motor can be removed under the front passenger seat in the same way the filter would be removed. There will be screws on the right side, under the glove compartment that you have to unscrew to take the blower motor out. Perhaps it's dirty or needs to be lubricated in certain areas. This is what I would check first if the symptoms you notice only happen when the AC is on.
You might have a leaf stuck inside the blower as well, you should open it from under the glove box and make sure everything is clean inside were the fan is.
Thank you so much fixed the issue you got insta? Needa follow you asap
LOL I'm glad it was useful! Sure, it's Leverage_Lifestyle
Why don’t you show people hows you removed the cover?
When I got the idea to record, the cover was already off, but that cover is super simple to remove. You can tell how to remove it just by looking at it!
Wtf BMW changed successfully engendered designs for ridiculous shit like this why!!
@J b yes , however some of the changes that are an inferior design I'm not sure actually saved money to produce . It's driven by a market that doesn't want to drive literally.
Bro talk too much
Dude you talk to much at the beginning.
But did you die?! :)
Don't waste your time. Dude doesn't show anything.
Others seem to have gotten value from it. If you're a DIYer, should be everything you need. It's just a few panels and screws.
