On my W201 I have managed to remove the access panel and have unbolted the motor and wiper assembly from the body including the little piece that attaches to the firewall.

Should the motor and assembly be removed as one piece? If so, I just can not figure out how to manuever them out, especially the motor. Is there another piece I need to remove? I could disconnect the wiper asemply linkage from the motor but, based on the vertical wiper instructions, it is not at all clear if this is something I should or should not be doing?

Any help much appreciated.
