There are 3 micro switches in each door. I don't know the year of your Boxster, but before ordering the door latch I would call Pelican Parts, give them your VIN and confirm which part is correct for your car. Here is an overview...

- 996-613-125-00-M100 - this is the micro switch for the left outside door handle
- 996-613-126-00-M100 - this is the micro switch for the right outside door handle
- 996-613-123-00-OEM - this is the micro switch for either the right or left inside door handles
- 3B1-837-016-P-M100 - here is an example of door lock mechanism. Determine if you need these (as they are expensive) and then call Pelican Parts with your VIN to figure out which is right for your car. This has a micro switch in it and is the mechanism in your door that contains the actual latch that engages when you close the door.

I've only fixed one door so far but it is my understanding that if you open the outside door latch and the window moves down, the micro switch for the outside door handle is working. If you open the door with the inside door handle and the window moves down, the micro switch in the inside door handle is working. If your window doesn't stay down while the door is open, your door lock mechanism micro switch and/or cam in this mechanism is bad and needs to be replaced. I hope this helps and please confirm any part numbers before ordering as I believe the door lock mechanism can change based on type of security system your car has, etc.
