Central locking problems - Finally a solution! PICS added.

After 1 year with problems with locking my car, i found something. I have searched the net everywhere, but the only thing i found was this: "Ford Technical Service Bulletin (TSB) 05-10-21 says to clean any corrosion from the door latch connectors, then pack them full of dielectric grease."

But it did not work.

My problems with locking/ unlocking:

- Happends when weather is cold and/or moisty.
- Central locking don't work on drivers door either with a key or remote.
- I can open all doors with a key in passengers door.
- Sometimes I hear a click from the doors, after 5 minutes from coldstart.

My exploring lead to this solution:

- I unplugged the drivers door latch plug. All 3 other doors suddenly worked.
- Focus central locking works like this. Ther are 2 tiny wires controlling the locks. One is for lock and one for unlock. When one of these wires gets earthed it locks/ unlocks. But these wires never gets earthed at the SAME time.
- So i used my voltmeter a bit. WTF! Both wires were earted. A SHORT CIRCUIT in my drivers door latch.
- So i wanted to have a little fun. I unplugged the latch plug in drivers door. Then i short circuit these two wires myself to simulate how the car would respond.
- The car responded exactly as described over, nothing worked. It even made this click sound when i took away the short circuit. Hurray!

What would you do if your wife told you to go left and right at the same time. Nothing right? Thats what happens when you give a signal to the car to lock/ unlock at the same time.

So now i have the biggest problem left. To either buy a new latch or to take it out of the door to clean it. The short circuit inside is probaly by water or dirt.

So now i am very HAPPY!
