edgar cruz says:

what are the signs of a bad regulator ? on my 03 330i my windows wont move but i can hear the window motor run. awhile ago i repaired the key lock on the driver door and a week later heard kind of a small clack sound when i rolled the window up or down and few weeks after that the drivers window wouldn’t roll, weeks after that the passenger window went out

Thanks a ton for the video guys, went perfect!!

Charles Mccuen says:

I just changed my regulator on front driver side window, but now my door locks don’t work, either manually or with the key fob. The fob does open the trunk though

Your Buddy Ed says:

Just completed the right side replacement after having done the left side a couple months ago and only problem is the airbag light is now on in spite of following the procedure strictly – making sure to disconnect battery and THEN disconnecting the airbag and then reversing the order upon completion. The first job resulted in the same thing so I’m not sure how to do the job and not have the light lit on the dash. Annoying ‘cuz I don’t have a code clearer and don’t want to spend $100+ to buy one that may get used one or two times. Seems like there should be a sure fire way of doing it that doesn’t result in the light coming on?

Travis Demaria says:

I cant roll my window up 5 inchs to get to the holding bolts someone please help me an tell me what to do

Rod Rich says:

After removing the negative battery terminal I still got an airbag light upon reassembly. Any ideas why and how do I get it off?

Guy F says:

Some regulators indicate they are either for single or double pane. How do I know if my windows are single or double pane?

Michael Lewin says:

Is this tutorial compatible with a 128i?

Vince Bobba says:

Followed your directions and the demo. It worked perfectly, thank you! Vince

venerated says:

Will the window stay in the closed position safely while you remove the regulator? That seems unsafe like the glass could fall. I notice at one point there’s a pry tool wedged in there.

tLWildThing says:

great tutorial!

Cliff White says:

Hi – I removed the old regulator & taped the window in the up position but it slide down completely into the door cavity. I’m unable to slide it back up. Any suggestions? Thanks.

Tolgahan Tireli says:

Today,you let me save 200 € just with this video. The service asked 280 € but I bought the part for 75 € and did it! Thanks for your efforts!

coledynamo says:

Great video just did this and its was spot on. took 70mins end to end for an idiot like me. cost £28 on ebay for the parts saved £480 on dealers estimate. thanks so much.

pgreenx says:

Hi my passenger door window goes up and down about 5 inches and stops. Does this mean since the motor is working the cables or something like that is stuck or should I replace the motor? Thanks!

Rick Morgan says:

I have 2001 325 ci convertible and was hoping for video for back window regulator and interior panel removal to avoid breaking anything removing panel. yet it seems impossible to get a you tube video on rear windows regulator removal unless rear window is also rear door. which I have convertible so no rear doors.

flipstakks says:

How do I remove the air bag light after I replaced the part ?

Caner Uzelgok says:

Hello first of all these are great instructions thank you for sharing. Installation went nice and smooth i did not have any problems. My only problem is i forgot to reconnect airbag before i powered car up. Now i have the airbag light on my dashboard. Is there anyway to remove this without going to a mechanic or dealership. Any help would be appreciated.

Didier Marcellino says:

can someone help. my airbag light goes on when I reconnect it. (I already removed the negative cable) but do I need to wait for a specify amount of time before removing the airbag.?
now the lights is on, if someone once how to fix it. thanks

Morning Glory95 says:

Now I understand why Otto didn’t make an e36 version of this video. The e46 has nuts and bolts holding up the regulator. The e36 regulator is Riveted ok and is much harder to get off.

Travis Demaria says:

Bravianauto please comment back

Ethan Humphrey says:

good video but this is gonna take 1-3 hours so prepare for that…

Steve Pan says:

i have a E46 and the window is stuck because the cable snap. how would i go upon removing the window

Renz Sadiwa says:

Hello i currently own a Bmw 330i and the problem is that my driver side window can go up but not down? At times when i would go into bumps the window just slowly goes down and when i put it up it goes up with no problem but going down it wont. I was wondering if the window isnt aligned ?Or the regulator or motor needs to be replaced?

donald eloriaga says:

Hi, i’m new here and from the philippines, after finally sourcing out torx t20 and t30 tools i was able to open up my e46 front driver side door because its stuck on closed, after removing the motor on the window, i still cannot roll down the window to remove the glass, seems to have stuck on closed, motor working as checked. Whatever rocking or knocking i do,

The front regulator seems to be working because whenever i try to work the switch, the front of the glass tilts forward, the rear part is stuck tho.
Unfortunately, to remove the rails, i need to remove the glass,

I cant reach in and cant even see the bolts attaching it to the rails. Is there another option than cutting up the cables to free up the window?

Window regulators here in the philippines cost an arm, a leg, and a kidney.

Followed all the diys i have seen but no one has written this yet so there.

Need help. 🙂

DjStiv3 says:

fuckin A, man.
What a pain, luckily i just want to replace my speaker for passenger rear door. Probably both sides so theyre the same.
Any thoughts from people, for replacing? get an original, get newer better ones, what kind of connection do they use anyway?

GuamanianBlood619 says:

Hey Bav Auto, my 94 525i currently has a seized driver door latch, I suspect this since the central locking works as well as the key, fine yet neither handle will release the latch, is there a way to manually release the rotary latch? I have removed the door panel partially giving me limited access to the latch . any help is greatly appreciated! , for now im left hurdeling over the center console.

Demon of Razgriz says:

Hello Bav Auto, my ’01 325i driver’s window keeps sliding down, but the elevation mechanism is working fine, what may be happening with it?

Heriberto Sanchez says:

I can not lower my window at all (not even manually) to even get to the window bracket, any help ?

KvnS S says:

What is the window being held up by when you removed the bolts that hold it to the regulator? I’m doing this on an E46 M3 and I have to remove two E7 torx bolts instead of the two bolts you removed at 4:54 in the video.

Kevin Hancock says:

hi you been great I have to ask (I need to purchase a new vapour barrier soon as the existing one is not holding up ) but I’ve not rushed to get one I want to do it 100% when I do it meaning getting the clicking noise sorted which I believe is the cable moving and hitting the door /glass when in motion I do know that when I got it out before a clip snapped which I’d most certainly say was a clip that held the cable in position but can I get these somewhere ? and if so how many should there be ? I have an e46 coupe reg mj55 ftc thank you

Salicious Crumb says:

What year is this BMW?What model?

RomeoMike says:

Very helpful resource that gave me the confidence to tackle this project successfully. Some further observations when I did the driver side front regulator on a 2004 E46:

1. The only cable bundle I had to unclip was the one attached to the inside of the door card.
2. Be careful in freeing up the vapor barrier, especially immediately below the window speaker as there are thin ribbon cables in that location that would be very easy to tear/break.
3.The only zip tie needing to be cut was in the top center of the door frame. On an OEM regulator, it goes around the yellow cable guard.
4. No mirror memory module to disconnect on the driver’s side.
5. If wire cutters fail to free up the window, you might have to remove the window motor to free up cables that might have wrapped themselves around the big white plastic gear of the regulator.
6. Lucked out with the new OEM regulator as it was lined up in perfect position to secure the window bolts when I manually lowered the window on it.
7. Window bolts take an 8mm socket, but for some odd reason, I had to step down a bit on one of them to a 5/16th to turn it.
8. Ensure the wiring for the window mirror switch is pulled through the opening in the arm rest before you reattach the door card.

Stev A says:

nice vid. here’s a question for you. the drivers window on my 2004 325i goes up and down, but seems to struggle getting back up near the bottom, and then get a little bit better as it goes up. is this the regulator or the motor? it has never failed to go back up, but it really struggles near the bottom, and i’m thinking about fixing it before it stops completely.
