Problem with window drop upon opening on 996
Discussion
Guys,
The passenger side window on my car isn't dropping. When I pull the handle the motor works but the glass only drops a mm or two a best. Has anyone else had this and fixed it? I am wondering if the window needs its travel points reteaching. The window works fine when you push the button both up and down. Any clues?

I had the same problem on a 2003 996 C4S, had to change the motor, found a second hand Boxter motor that did the job. Until it was replaced had to manually shut window using switch inside the car........right pain until sorted. Good luck.
So yours still worked fine with the switch, just not the convenience opening, like mine? How hard was it to change the motor? It seems strange that I can hear the motor try to drop the glass and that it works fine with the switch.Just reviving my old thread here, I haven't resolved this yet and need to pull the door trim off. But I have established that the rear of the window drops but not the front and you can push the front of the window down the 10mm or so that the regulator has dropped. I presume that there is either a clip broken on the bottom of the glass or the regulator needs some form of adjustment where it connects to the glass at the front.
So before I pull my door trim off does anyone have any experience with this?

I fitted the new regulator today and everything went well, my window now drops front and back when you pull the handle, as apposed to just the back of the glass previously. Now I am having troubles teaching it the limit position but I will work on this. As there is very little on the net in the form of a DIY basically you need to:
1.Remove the speaker.
2.Lift back the foam door card seal.
3.With the window raised remove the two oval rubber caps near the top of the door at the front and back above the foam seal line.
4.Undo the two torx screws these these expose.
5.Lift the glass up out of the door.
6.Press the down switch and drop the window mechanism.
7.Remove two more oval rubber caps from underneath the doors to expose two nuts.
8.Before undoing the nuts get a pencil or scribe and mark where the mechanism bolts in the bottom of the door to save you playing with the adjustment after fitting the new one.
9.Undo the two nuts underneath the doors and two more of the same nuts at the top of the doors.
10.Undo the three bolts holding the window motor to the door.
11.Cut or unclip the cable tie underneath the airbag holding the regulator cable in place
12.Remove the window regulator and motor in one piece from the door.
13.With the regulator on the ground undo the three 13mm bolt/studs that hold the motor to the regulator. Take note of its orientation.
14.Where the motor bolts in to the plate on the new regulator the holes aren't tapped. I tapped mine, but you may be able to cut a thread with the bolt if you are lucky and don't strip it. I would highly advise cutting the thread though.
15.Bolt the motor to the new regulator and on the 996 remove the top white window stop at the front/bottom of the regulator, if unsure you will see it when you let the window down for the first time.
16.Fit the new regulator in the door and line up the bottom of it in the adjustment grooves where you marked the door before removal. Tighten the 4 nuts that hold the regulator in and the three that hold the motor in.
17.Drop the glass in the top of the door and sit it in the regulator, don't tighten it up in the clamps yet. Look to see where the glass was clamped before and align this up.
18.Wind the window up.
19.Make sure the glass is pushed forward in the channel and then put a screw driver in the door latch and close the latch so the glass goes up that bit higher (as if the door was closed)
20.Tighen the glass clamps through the holes that the oval caps cover.
21.Check the operation, if unsure about the window stop wind the window down all the way and you will see that it sticks up above the door i.e. doesn't go all the way in to the door. Look at the front of the regulator down the boot and you will see that there are two window stops. The glass is hitting the higher one of the two which is for the Boxster I think. Remove the top window stop by undoing the torx screw.
22.Now everything should be fine, check operation and be careful when you first close the door to make sure the glass isn't too high.
Refit everything up and do the reteach. Probably allow about 2-3 hours if you haven't done one before.
