Hi all..
As we have been pounded with incessant bad weather here, I have now really got to sort the side window gaps in my '99 slk 230!I have done the usual windows reset thing pressing buttons in the correct order for 10 secs in position 2 on the ignition etc.....
Side widows are riding up outside of the top seals on closing. The height would seem about right but the angle seems a little out. I have been reading the various threads / posts here and elsewhere and it seems there are two plastic grommets(or more according to some) on the bottom of the doors that need to be removed and bolts that can be adjusted. Well not on mine! I have 1 large grommet with a torx screw head behind it at the non hinge end of the door...?? any ideas??
I have read all about taking off the door cards to check for missing brackets on the door glass but I am reluctant to start such work as I need to work outside and it will be the signal for another deluge of rain as soon as I disconnect the battery!!

If I understand you correctly, your windows are rolling up too far. That was the case on our 1999 SLK. On ours, it was the "L" shaped stop that is glued to the bottom of the glass. To find it you must remove the door panel. Once that is off, you get access to the area by removing the large speaker. There should be 2 of the "L" stops glued to the window. They are in the same spot towards the front of the window. One is on the inside of the glass and the other on the outside. With the window down you should be able to see (and feel) them. If they are not both there, feel around on inside if the bottom of the door for the one that has fallen off. I roughed up the glass a little bit with a dremel tool, cleaned the old glue off the "L" bracket, applied some epoxy, then clamped it in place to dry.

Once both of the brackets are in place, the stop can be adjusted. The "L" brackets hit the stop, which is held in place by a nut. With the door panel off, you can see this a few inches below the top of the door. I believe that the nut uses a 10mm socket. You will see that the stop assembly can moved up or down to determine the stopping point of the window.

Good luck.

This is a very common problem on the SLK's and as EL_Torro states is caused by the L end stops falling off the windows!
This is in my opinion a design failing of this model (R170) and Mercedes designed the R171 to electronicly drop the windows a couple of mm on opening the doors and raise them again after the door is closed, this type of function has been included on other cars with frameless doors for many years!

I am in the middle of designing a module that will perform the window drop and raise function to clear the rubber seal when closing the doors using a simple circuit, I am near the final stages!

If you would like to know more keep an eye on my thread

The door card removal is not that difficult. Back by the latch and above it are 2 plates held in by small screws. Remove those. Then the plastic triangle by the Side mirror needs to be taken off. Then you pop off the cover to the interior door handle to get to 2 of 3 screws. The 3rd screw is behind the plastic rectangle that shows SRS up be the door lock. It would be a good idea to disconnect the battery before doing this, but before you do that, make sure the window is down all the way. There are (supposed to be) 5 or so clips that hole the bottom of the door card to the door. Most of ours, if not all, had become unglued from the door card. It is easy to see where they belong, and I used Gorilla Glue to get ours back attached. Once the clips are off, you raise the door card upwards. It will remain attached with the cable for opening and the small speaker in the upper corner. Disconnect both of those and the door card should be fully detached. The larger speaker will then need to be removed. The plastic vapor barrier is the only remaining item between you and the openings to get to the areas you need to access.

When you find the "L" bracket you will see that there is a small hole in it. I elongated the hole in ours. The reason I did this was in order to fasten it to the other "L" bracket so if the glue fails, the stop will not get out of place. I did this with a very small screw and nut.

Hi.
I have the same problem. The "L" brackets have fallen from the window. What kind of epoxy can i use? A brand or something. Can i make a hole in the window so i can put them together with a screw?
P.S: Please excuse my english. Is a little rusty!

This is the product that I used:

http://t.homedepot.com/p/Loctite-0-47-fl-oz-Five-Minute-Instant-Mix-Epoxy-1365868/202020459/

Only the inner "L" bracket was off on mine. In addition to being sure all the old glue was off the surfaces, I roughed up the window some. The final thing I did was bolt the 2 brackets to one another after they were in place. I did not do it horizontally, I did it vertically through the brackets themselves. There were already small holes in them, I just elongated the hole in the inner bracket and made sure I could get the bolt through when they were in the proper positions before I applied the glue. I believe I just a 4mm bolt.

No, there are no holes in the glass. The horizontal part of the 2 L's have a small hole in them. I elongated the hole on the inner bracket so the small bolt could pass through when back in place on the window.

Hi,

It could also be that the glass has just popped out of the holder at one side usually the front. This will make the glass higher at the front ,but the glass being at an angle at the back of the door.

Just unscrew the nut and pop the glass back in and tighten up.

Regards,
