Driver Window not Dropping

[jlang996]

I recently had this problem with the driver side (RHD) window not dropping when pulling the handle (inside or outside). Also the alarm would double-beep when unlocking, and the cabin light didn't come on when the driver door was opened.

Tried a number of things - replaced handle microswitches (no effect), replaced and reprogrammed Alarm CLU (had got wet so was prime suspect - but no effect), and even removed the carpet (as it needed to dry anyway) and checked as much of the wiring as I could get to between the CLU and the driver door). Finally replaced the door lock assembly with a VW part (£26 from Amazon UK compared to £200+ from Porsche) and a) the lock fitted and works a treat and b) all the above issues with the window drop and alarm beeps have been resolved!

I would recommend anyone with similar problems checking the lock assembly before experimenting with more expensive parts of the system!

Hello all,
New to this and appreciate all your help and advice
I have a 02 Boxster, 110 k miles on it and absolutely flawless. Never seen a raindrop and runs drives and looks new
Today I took the wife for a ride and noticed that the passenger window drop was not working. Also noticed that when the handle is operated and the door opened the interior lights are not coming on either ( don’t know if that’s a factor in diagnosis)
The windows both drop halfway down when the roof is being dropped or operated and both windows work correctly when the buttons are pressed
I can hear the microswitch clicking as it should when I operate both inside and outside handles.

Ok so 2 AM and because I’m neurotic I decided to start taking the door apart just to rule out the stretch cable and have a look
I found that when I wiggle or even touch the door lock mechanism the window drops
Even with the micro switches unplugged if I even touch the door lock mechanism ( basically touching the larger plug on the bottom the window drop function works

So is it safe to say the door lock mechanism is malfunctioning?
And do I go for a VW replacement? Or used ? Or am I totally wrong about this ?
Thank you in advance

Ok , so thank you for not responding!!!
Anyway, I changed the lock assembly and the problem has been corrected. So if someone should have similar symptoms, I too strongly suggest changing the lock assembly. I got mine aftermarket for about 35 US. I did have to cut the red plastic mechanism for the key. My car is keyless so wasn’t a problem. Job took about 1 1/2 hours. Go slow so you don’t miss anything going back tog
