left rear window does not go all the way down, preventing the soft top from operating, this occurred after a battery change.

Did you normalize all four windows? For the rears make sure you hold them all they way closed and all the way open to normalize.

Don't know what you mean normalize, other three operate correctly, left rear will only go down a few inches, not all the way regardless of how I depress button.

To normalize the windows close the doors, roll the windows up but don't go past the auto feature detent in the switch. Hold in the up position for about 5 seconds. That should normalize the fronts. For the rears you may also need to roll them down using the same method. After they are normalized the auto feature should work on all the windows. If it still doesn't work you may have a fault or may need a code cleared.

Lol, the left rear does not go all the way down , so cannot "normalize" it in down position.

any new suggestions?? any mbz technicians here? is it possible that there is an error code blocking the window reset??? will this force a trip to dealer to reset error code???

Were you able to fix it? Cause I have the exact same issue. Except I never disconnected the battery at any point in time. One day all windows worked fine and now one wont open all the way or close all the way. Same Window, rear driver side. Let me know what you did to resolve the issue.

I have the same issue with the same back window going back about ten inches and stopping and top will not go down. None any of the suggestions have worked so far. I also have a problem with the top coming apart in the seam on the back side of the top. I have taken good care of the car and it seems to be falling apart. Is there a glue that will hold it together or do I have to replace the top?

my lemon of a car a 2004 merc clk320 bought 9 months ago and 3 months later i parked the car then heard a snapping sound what sounded like wire i knew a day later what it was when my rear right hand side window was making a broken glass like noise and window was not going up i had to use my hands to pull it up. today i was hit with the soft top not pulling back i believe its because of that rear window. this page has further confirmed hat i suspected. conclusion mercedes b's are a pile of shit and an untrustworthy german crap. This is besides other issues that ave gone wrong and i hardly drive this pile of $15,000 lemon. its going to cost me $800 to fix at a car wreckers, im thinking what's next.

p.s left hand bearing noise just hear it, heater taking forever to heat up then its mild heat wen it does come, sensors not working Mechanic unable to fix the problem. at times my two front windows don't go down i have to press the button a few times. left window won't go down on its own when pressing button". rear boot cover i get a message telling me to adjust before opening soft top always, but now that's no longer working from as of tonight. alloy wheel rear a month ago keep getting a slow leak i find out it has a hairline crack in it because its alloy. I hardly drive the car so i don't have further issues. i still get issues. what a fkn lemon and this car was past for road worthy"!!!!!!!!!!. what a fkn lemon do not by mercedes b" if you don't want a continual nightmares.
