I had my wiper mechanism removed out of my w201. i know the w124 uses the same viper mechanism but I'm not sure if the procedure to remove it is the same...

To the point...it's really an easy job removing this out of the w201. So if the w124 is similar...take it apart. It shouldn't take more than 10-15 minutes to remove the whole assembly.
