Besides for putting something into the door latch which creates that damn ding noise, i let it ring and and found the source of the noise. It is a little rectangle metal box located by the fuse box underneath the dash, which you can pull down by a little latch there, mine popped out pretty easy, i used a flat head screwdriver and pushed down on the latch till it just popped out about 2-4 cm Thats all you need, the ring is disabled. NOW, before anyone else goes and does this i noticed that ford put something with the circuit to that little box things that make other items on the car act wierd. From what i remember my wipers did not turn on when i would goto put the sprayers on, meaning when you put the squirters on the wipers had to be turned on manually. I think there were a couple of others that i cant remember but watch for things. So i guess it makes the ding go away but other stuff doesnt work, it should be done with your own opinnion.
