Few issues need help
 

I am visiting my mechanic this Friday, for a full service.
my boxster 2002, I ordered a new key and he programmed it all works fine.
now, when I lock it, sometimes, it makes a horn sound, indicating something is open, but everything is closed, doors, windows, ashtray, roof, and the lock button on the dash is like red. any idea why it does that? it sometimes also does it when I unlock it.

issue 2:
when you open the door the window is supposed to open a bit so u close the door and then close back so it doesn't hit the edge on the top.
sometimes it does open sometimes it doesn't, like it gets confused, (driver side) on codriver its ok, any idea what to inspect? dust etc..?
I tried holding the window button down for 20 seconds to reset, but I don't know if it worked, since I still have it. it cannot be the regulator, since sometimes it works.

The window drop is likely the microswitch in the door handle.

For the alarm horn, sometimes it might be the center console lid. Try closing it firmly and seeing if that may make a difference.

thanks, so microswitch, is what I will tell the guy, he needs to open the door I guess to check this yes? replace it maybe? check it maybe some dust etc..?

Symptoms very much -- identical? -- to the ones my 02 manifested when what proved to be the passenger side door lock assembly was bad.

The tech hooked up the diagnostics computer and read the codes and did some other things to see if the problem was due to some other component as the door lock assembly is one of the most expensive items but it proved to be the door lock assembly.

Be sure the cabin floor under the seats, the passenger seat in particular, is dry and the doors do not have any dampness at the bottom areas.

thanks I will bring it to his attention this Friday when I have the service of the car.
