Porsche Boxster 986 – Door Mechanism Repair.
This page will show some photos on how you can repair a Porsche Boxster Door Mechanism.
This page is helpful if your driver or passenger door will not open when you pull the handle up. (The glass will drop but the door will not open.)
In Short:
The plastic part that connects to the threaded bar on the door handle mechanism either comes unclipped or loose. Just take the door trim apart and use a torch to reclip this back on. I did use a cable tie/strap to prevent it from sliding off again although I think it maybe just vibrated undone after years of driving.
Note: do not put the black plastic part all the way up the threaded bar as it will not allow you to drop the glass before you open the door. It will open the door and drop the glass all in one go which is not correct. So just adjust the black plastic part on the threaded bar to overcome this.

The black plastic part here has a slot in so the threaded bar can be pushed into it from the side you cannot see. Once in you can slide the larger black plastic part down towards the threaded bar to lock it in position.
