I have a 2005 slk350 r171. The problems started when I attempted to close the convertible hardtop. The top would not latch nor would the trunk close. I relieved the hydrolic pressure using an Alan key at the position behind the center console. I manually closed the trunk and put the top up. Then secured the top using an Alan key to tighten the emergency lock. I now need to get the windows to return to the normal position as if the roof was closed. I never intend to use the vario roof again. This has been a nightmare. Any help is much appreciated!
