Window 1/2 inch drop not working + alarm double beep on unlock

[RedCobra]

Hey Guys,

I usually do a lot of searches on topics before I ask something. Its a 2000 911 C2 Cabriolet - All of a sudden in the past few days the car shows the following symptoms

a. The car randomly double beeps on unlock

b. The Passenger window does not go down 1/2 inch on the passenger side - This is the same behaviour on both the outside and inside handle - Does not happen on the drivers door (so I assume its not the convertible top switch)

c. The interior lock / unlock switch remains lit even during engine running and when the doors are unlocked - Pressing either side will double beep the alarm

My searches brought me to this thread...

I see that the person on the post did a reset by holding the up and down switches at the same time. I am wondering how would one do that as the switch is like a toggle kind.... Every once in a while it becomes ok and everything seems to function normally and if I try to lock the doors on the inside and unlock the doors then the double beep comes back.

Is there anything else I can do - I dont have access to a durametric tool...

The passenger window goes up and down normally without any hesitation when I press the up/down switch on the center console.

Thanks

A double beep means there is a fault in the alarm system. You need to find the fault (cause) of the double beep. It could be the door handle switch or it could be something else.

Further diagnosis really requires a PST2, PIWIS tester or Durametric Software.

I think you need a new door latch. Here is how I replaced it

on a 997.

This fixed the 1/2 inch drop. I think this part just wears out

over time.
