Excuse me for this rant, but I have to say it...

Does anyone else have problems with their front windows on their coupes? Every time it gets a little frosty outside the window refuses to scoot down the 5-8mm it needs to to clear the frame that it hides in! What a stupid design! A buddy of mine has a 2005 G35 Coupe and it has the same frame-less windows that tuck up to, however they are non-interference. Meaning if you don't notice and still slam the door, they aren't going to hit the body and possibly break. Did the Germans not cold weather test these cars?

no trouble with mine, even at 17 degrees F. But with snow and ice all over them, I was real careful closing the door. Mine is a 2004 325ci, but low miles. I too think it is a stupid design and will surely fail as it will just wear out the regulators. How many miles on yours?

Mine has 117,000Kms(72,700 miles) on it. I don't know if it's the glass freezing to the wiper (at the belt line) or if it's an internal problem with the regulator. Once it warms up or I "persuade" it it works flawlessly. This morning the outside temp display showed a chilly -14 C (6.8F). Could just be the Canadian factor with these cars, seems they hate cold morning starts.

It's happened to me just once; the driver's window was frozen shut but the passenger's worked. I'm just sure to dry the edge of the window and the rubber seal if I open the door and it's wet and cold out, like when clearing off snow.

I've never had a problem of the window being too high and hitting the trim, just the one time where it wouldn't move down the tiny bit needed to clear the trim.

Never had any issues with mine, even when it is below 0 degrees. I had the drivers window regulator fail once though.

same problem

my roommate has a 2002 325ci. his passenger window never budges. it results in a large scraping noise as you try to open the door. he has to:

1. roll down his passenger window
2. open the door to let his passenger out
3. have them close the door
4. roll up the window

an extreme hassle, I think he is going to take it in because its still under warranty. ill let you know what the dealership says when it gets fixed

p.s i forgot to mention that we live in sunny socal so it never get below 60 degrees

I seriously doubt that it is due to a faulty or failing window regulator. I'm positive that it is the glass freezing to the door. I think it was an oversight to design it the way they did. I'd buy another one though. A used BMW is better than a new Chev.

The windows guides could be getting warped some when its cold vs. warm outside.

So your left with 2 possibilities.

1. The door guides are miss-aligned, and you will need to re-align them.

2. The window regulator is too weak to get the job done.


Eitherway, you can take your door panel off fairly easily and fix either problem in under 2 hours.

I have replaced both my regulators and door lock actuators in both doors, only took a few hours and I am not a mechanic.

Isn't it the lock actuators that actually control the mechanism of the scooting up and down feature and not the regulators? :confused:

next time try to splash a generous amount of warm water around the top of the window seal and on the trim at the bottom of the window. If still not working, at least you know it's not the window getting stuck in the frame because of the cold.

I've already replaced the door lock actuators no problems, which have NOTHING to do with the windows. I'm quite competent when it comes to working on my cars. Let me just clarify that it is not the COLD (ie temperature) that is causing the problem. It is the glass freezing to the felt/rubber wiper at the belt line. The window regulators work just fine (although, I'll admit they could be "weak", they are original). The windows are capable of coming down when frozen, they have in the past and continue to do so, when operated by the switch. The car is always parked outside and is exposed to wet snow and ice overnight. I'm not too concerned as to why it happens, only stating that BMW should have made it a non-interference design. Which I know no one here can change or do anything about :) It's just a quirk I guess.

OP...I feel your pain!! :bow::bow:

I am from UK and maybe we dont get the weather as cold as you but it has barely got above 2degrees c for the last 3months.....!!

Anyway when you pull the handle and the glass drops 4mm, my glass had only half defrosted so the half nearest the wing mirror dropped and the other half didnt....

As you can imagine, it didnt do the pillarless glass any good...!!

Window regulator clips broken, when I ring the stealership to get a replacment clip....oooops!! E46 is the only model BMW which doesnt do just the clips, it was a full new regulator....!!

Apparently the Audi A6 clips can be modified but its too cold to be doing that!!

The Germans built an amazing machine but its like they gave the idea to some sh!tty company like Fiat to do the Window mechanism...!!

Grrrrr!!!!:censor::censor:

Rant complete :)

Over and out :thanks:
