Window hesitates and sounds like it is breaking

Hey Guys,

When I roll down my passenger window, it seems to hesitate around the half-way point and make a slight cracking sound, and then sounds like it is scratching for the rest of the way down. Does this mean the regulator is about to give out, or is it another problem?

Thanks!

yup, more then likely... it was a warranty issue back in it's day. common with e46. remove the panel, remove the seal that separates the panel and door and give the window a run. Check to see what is happening inside.

before my regulators failed it sounded like the window was cracking. it would hesitate going up and down. get it replaced before you are stuck with them down.

I had the regulator replaced at a shop, but now I get wind noise and the window won't roll completely into the door

Also, there is still a cracking sound, but it only happens right as the window starts to open, and again about 1/3 of the way down. There is no more grinding/scratching sound though.

I guess I have to take my car back to the shop. Do you think it is a faulty regulator, or a poor installation job?

Thanks!

well, you now know they are liable to fix it - cause you paid for a job to correct the problem and not for it to persist. They should have caught that after installing it.

They noticed that it was still making a cracking sound, but they didn't notice the wind noise or the window not rolling completely into the door (about 1/2" of the window doesn't roll into the door).

I'm going to have to take it back, but it's quite a hassle having to arrange for rides to work and stuff

The worst case I've had happen is the wire snapping, and when that snaps... it literally sounds like your window just shattered. But really I didn't... atleast it shouldn't.

Either way it could be signs that your window regulator is weakening, and will need replacing very soon...

my advice is once your windows are up do not bring them back down because if the regulator shoots when its down then you wont be able to bring it up...

its an easy DIY

The window regulator had already been replaced once before; however, I was still having the following problems:
  • A little bit of wind noise at highway speeds
  • The window would not roll completely into the door (about 1/2" left to go)
  • The window would give a "cracking" sound when rolling down at about the half-way point
I took it back to the shop this week and they replaced the window regulator once again. I no longer have any wind noise, and the window rolls completely into the door; however, there is still a fairly loud "cracking" sound when rolling down the window. The mechanic said he had tried for a long time to correct it, but to no avail. He thinks that it is due to a slacked cable that tightens when rolling down the window, giving off the cracking sound. The sound only occurs about 50% of the time now. At least the wind noise is gone . . . that was bothering e the most. I can probably live with the cracking sound so long as it isn't wrecking anything.

What did they replace? Was it the whole regulator or a piece of it. If the window has a crackling sound that's the cable from the regulator. I've changed 2 on my car and unless the cable is replaced there's no way to 'fix' the crackling sound.

Did your mechanic give you your old regulator when it was replaced? Hopefully your mechanic didn't just try a cheap 'fix' and charge you for a regulator.

Your first two issues are about adjustment and the third issue is definitely the cable/wire.

That happened to me just before the summer ended......exactly the same stuff you're describing....

It was the window regulator, the wire gets threaded and it will no longer pass through the wire loom.


If you had your regulator assembly replaced the window should go up and down super fast and extremely smooth!
If you still hear noises, its the wire that got threaded.

You cant by only a single part for this, you have to buy the whole regulator assembly.........I bought mine from bmw of sauga for 270.

Installation is super expensive if you take it out but i did it with myself and had my dad help me....it will take 2-3 hrs and its almost very straight forward.

The cracking sound is most likely one of the sliders are catching on the bottom of the window edge and or due to the stress put on from the previous regulator something may have bent causing interference. at least this was a common problem on e36 models. I would open up the door and play with the window to listen and look at where the problem resides. If this persists you could probably be in for another regulator sooner then you think.
