not a new problem, had the same issue sometimes on my 1997 S class, never had a solution...

I was thinking about waxing the drivers window to minimize any drag.

Might as well NOT to use the window at all....but this is just not right.

Do you think it's a friction problem? Maybe some sort of lube on the tracks... It seems like when it reverses its because the safety...

I also have the same problem, it seems to only happen when the temp is under 40 degrees tho...

auto-up will not work, when i hold the lever up it will go all the way up, close and then reopen about 1/2in.. then i have to pull the lever up again to close it....VERY annoying

it is pathetic MB will not recall this problem

It is the safety feature. The system obviously reads too high amperage at the window closing motor and stops the closing movement. When it does this it will back the window down slightly to relieve pressure on the assumed human body part.

This is about friction forces with the system, which can be internal mechanism or the window itself against the seals. Seems like MB thinks it is the window/seal friction issue as their fix is to change to a thinner glass. I would rather change the seal material myself.

It also seems that the system needs to be reset after this happens just once. This is done by holding the switch to close the window and keep holding the switch for about 5 seconds after the window is closed. I have been lucky with this as it has happened only once on the driver's door.

Interesting to read that someone has the issue with lower temperature. Rubber gets harder and shrinks with colder temperature so this all should lower the friction between glass and rubber seals so it points to the direction of friction being too high in the mechanism inside the door. Perhaps they use wrong kind in lubricant there?

EXTREMELY annoying to the point of ridiculousness. I have never experienced this with BMW.

And I thought I was crazy!! My Driver side window won't go up one touch, I have to hold it manually. When it gets closed it reopens about 2-3inches really annoying. The passenger window does the same thing.

I've told my SA every time I've been in for service. He says the same thing "We've reset the windows for you"

Like is this issue not going to go away!?

I thought this happened to me because mine is a CPO car.......but I guess, I am buying something that a $15,000 Korean made car won't have that kinda problem's problem that I will have to deal with for the next 5-7 years.

I have the same problem on my passenger side. Took it to the dealer and they reset it twice but never fixed it.


I have a different problem on my drivers side. Sometimes when I roll down/up the window, I get a scratchy noise as if there is sand in between the windows. Dealer tried to fix it and blamed it on the NON-MB tint.


Gave up on both and just dealing with it...

im having the same problem it sounds like with the rest of yall.

it feels like the window regulator has a mind of its own. whenever i press it down completely to roll it ALL the way down, it rolls down completely (until I press it up to stop rolling down) without any problems whatsoever.

BUT, the problem occurs when im trying to roll the window back up. both driver side and passenger side and it seems like it only suffers in the fronts. never in the rear windows.

I would press it to auto-roll-down and midway through, ill press it upwards so itll just stop rolling down. but, instead, itll stop for a second, and then keep rolling down all the way. so what i have to do is then press up again so it stops rolling down further, and then hold it up so it rolls up until the desired height. it is VERY annoying and I wanted to take it into the dealership for the huge inconvenience.

but i do have window tints. so if they try to tell me its not under warranty because of window tints, i will flip a sh!+ like a dirty little chinese man with a small third leg who can only blame his shortcomings to God for f&cking him with an unfair gene. oh it will be hell up in there. i just want my car to be perfect, since right now at this point n my life, nothing is perfect. please Help me Lord.

This must be common in the cold weather, I'm glad I don't have that problem.

The scratchy noise comes from the glass being dusty or dirty. Sometimes, the small partical might stick to the interior belt molding.

Different Window Problem
 

I have a 2011 E350 Base. The driver's window will only go up or down in 3 inch increments. I have tried the reset procedure, and that does not help. Any ideas? Thank you.

you have tried resetting driver window but it moves in 3" increments..
Your window is denormalized.

Use a cReader Elite scanner to retrain the door control unit.

THANK YOU
 

Thank you. I am educating myself on this scanner. A bit intimidating, but I'm on it. Thanks,

Window Position Sensor
 

I took it to my guy, who has a scanner. He said the scanner came up with a fault: "window position sensor" is out. Is this part of the window motor? This all happened after I changed the door control module, but everything works except the window stopping every 2-3 inches. The door control module actually caught fire, but all is well there. Could the window motor be damaged? Thank you.

toasty module
 

you simply need to "nomalize the window position" in the door module scanner menu

Thank you. I appreciate your help.

I'm baaacckk. I paid Mercedes-Benz $200 for them to tell me the following:
1. They cannot normalize the window position because of one of three possible problems:
a. There is a voltage problem;
b. There is a problem with the control module; or
c. There is a problem with the window motor.

I hate to bother you again, but I would appreciate any advice. Thank you.

The door controller is in charge of managing this. Unfortunately it can develop oxidized pin connections.

You can replace the module or try to get yours fixed with simple electronic solderings.

To train window position buy yourself a $150 LAUNCH Elite scanner - It may or may not help you code the replacement by transferring data over. Test and report.

As always, thank you very much for taking the time. I appreciate it. Keene

From what I am seeing on line, here is what I think. First, I replaced the Door Control Module. I removed and put back the door panel several times.
1) In replacing the door panel, I have impinged on the movement of the window. However, it does not stop and go back down, like when it hits an obstruction.
2) The Hall Sensor in the window motor is faulty, which would require replacing the window motor.

Thoughts?
