The problem is the handle is a little stiff and when I release it (after shutting door) the handle doesn't always go full back in.

Yes I am sure that my window stay down when I use the interior handle, but goes up when I use the exterior handle.

Suspected cause
While I acknowledge this problem is probably a real PITA, I have to smile thinking of all those German engineers slaving away designing the most complicated mechanism for solving a problem that does not really need to be solved.
Outcome qualification: Negation, uncertainty or missing explicit repair resolution overrides the raw extraction signal.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I just need to understand how the microswitches in the doors affect things then I can easily fix!
You pull door handle, window drops OK an inch or so.
But close the door and it doesn't always go back up.
Window works fine (so motor etc OK).
Are there 2 microswitches? one for door open(/closed) sense and another in the handle? Any others?
thanks for tips!!
(yes I did a search for this, but didn't find any others with same symptoms)
There is also a microswitch within the lock mechanism (in the door). You cannot service it without taking apart the door. It's purpose is to detect if the door is open, or closed.

I have a variation of this problem with my drivers side door. When I open the door from the outside, the window goes down but goes back up as soon as the handle is released. When I open the door from the inside the window goes down and stays down until the door is closed.
It would seem that if it is the open/close micro switch that is bad it would go back up when either handle is released. Any insights?
I had a similar issue last year. Are you sure the window stays down once the door is opened using the inside handle? That seems odd to me. In my case, the window would go down when either handle was used, but would go back up as soon as the handle was released. There are three micro switches involved. One each for the interior and exterior handles and one that detects whether the door is open or closed.
I needed to replace the driver's side door latch. The microswitch is part of the assembly but is not available by itself. Some have fabricated a new switch by cobbling parts together. I replaced the entire assembly - about $140.
Yes I am sure that my window stay down when I use the interior handle, but goes up when I use the exterior handle. Kind of strange, but that is the case.
Dharn - My window would drop with either handle but would raise again when I let go of the handle when the door was open. I was able to stick my finger in the receiver slot of the door latch and move the mechanism a bit. I could get the window to drop again. In my case, replacing the door latch fixed the problem. The symptoms you describe are kind of confusing.
OP - Let us know what you end up doing, how the install goes and if it fixed the issue.
I'm getting ready to do this myself, as both driver and passenger side microswitches on my 996 are acting funky.
While I acknowledge this problem is probably a real PITA, I have to smile thinking of all those German engineers slaving away designing the most complicated mechanism for solving a problem that does not really need to be solved.
Cars have been made for eons with window seals that work just fine - even in hurricane speed winds with no leaks.
Why didn't Porsche simply use the same system they've had in earlier 911s?
I believe I have isolated the issue to the door handles - based on this thread as well as other threads I have read, I have deduced that if you pull the handle - and the window goes down, but then immediately back up when the handle is released, it is the microswitch in the associated handle. If the window does not go down at all when the door handles are pulled, it would be the microswitch in the lock?
Or do I have this backwards, and thus if the window goes down when the handle is pulled but then back up when you release then the microswitch in the associated handle is fine, but its the microswitch in the lock that is faulty?
Correct me if im wrong.
Not to hijack OP's thread - but in response to your question Wyovino - my windows go down when any handle is pulled but do not stay down when the door is open. A real PITA having to explain this to passengers or cringing everytime the close the door with the window not down properly
"Or do I have this backwards, and thus if the window goes down when the handle is pulled but then back up when you release then the microswitch in the associated handle is fine, but its the microswitch in the lock that is faulty?"
This.
I've fixed both problems.
If the window doesn't drop when the handle is pulled, it's the handle micro switch.
If the window drops but comes back up when you release the handle and the door is open, it's the latch micro switch.
Well - Thanks for the clarification. Now I won't waste time or money chasing the issue.
At least I can identify whatever is rattling in the driver side door - now that I have to remove everything
It's really not that bad. I would disconnect the battery if you're going to replace the latch as you have to get pretty close to the airbag. If you're replacing the latch, note that those are triple-square bolts, not Torx.
OK I found the problem -
all the switches are probably fine. The problem is the handle is a little stiff and when I release it (after shutting door) the handle doesn't always go full back in.
It sticks out a few mm,
and I guess that means it doesn't activate the microswitch.
So despite the door being shut, it thinks I am still pulling on the handle a little, so keeps the window down that inch.
So I guess I need to take off the door card and look inside. maybe just oil the handle mechanism
