Window doesn't drop

[elav]

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.

What's the diagnosis if the (driver's side) window doesn't move when you pull either the outside or inside handle, but you can hear something working like it's trying to, and the auto up/down works perfectly when you operate the convertible top.

When I give a short pull (maybe 1/2 inch) on either the inside or outside handle, I can hear -- maybe even feel -- something move, and then hear/feel it move back when I let the handle back in. However, the window glass doesn't move at all.

As it is right now, I just always have to push down slightly on the top of the window before I close the door.

This is one of the more frustrating problems on the Boxster. I had a similar problem recently... the window moved, but not enough. I fixed it by adjusting the regulator. It seems the cables stretch to the point where the window won't drop. Some regulators have and adjuster (like a bicycle cable). Even with the adjuster fully extended my window was not moving enough, so I added a spacer to take up more slack and the window now drops enough to clear the top. I installed a cheap regulator I bought on eBay and it is still working 3 years later.
Regulators that don't have adjusters can be tightened up by using zip-ties as spacers... there is a thread somewhere on this. I used a short length of fuel hose held in place by a zip-tie.




This is an earlier thread on another problem that I had with the window... there is some interesting information in it.

Well, you only listed 2 micro switches. The door mechanism isn't considered a microswitch, even if there is one inside it.

[PLP]

Is there any adjustment to them?
Today the passenger door all of sudden worked. Just once... so either the microswitches operate intermittently or something does not pull them far enough.

[Stl-986]

No. When they go bad they just need to be replaced unfortunately. It isn't something that has to be done though, you can just live with it. Had one that had the driver side go bad. I just got used to rolling the window down some before getting out and using the key to close it when I got out. Was really only an issue when it was storming out.

@PLP - how are you making out? I fixed the passenger door today. Replaced the 2 micro switches in the door handles and the door latch that has the 3rd micro switch. The door latch mechanism that was in there had a short and actually blew a fuse as I was removing it. Car is now 100%. I actually also had a issue with the spoiler. I’ve seen a lot of videos of people replacing the entire unit but not restoring. After 20+ years the grease isn’t any more. I disassembled that, re- greased it and that is now working perfectly too.

Great news
Where did you get the microswitces? I need to tackle the same issue on the passenger side door as well.

I bought the door latch from our host but got the inside and outside door handle micro switches from a wrecked car at a pick and pull.

Perfect, thanks

Actually that might be what I face here.
On random occasions a fuse gets blown. No apparent reason.

I have not done anything yet. These are secondary issues. First are tires (actually wheels, going back to OEM, as the 19s rub on rear fenders), tail lights, and suspension inspection.

I will start working on them next week or so.
Funny thing is that I get them to work correctly from time to time... so I hope for a cheap resolution.
