Central locking problems - Finally a solution! PICS added.
After 1 year of 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:
My exploring led to this solution:
What would you do if your wife told you to go left and right at the same time? Nothing right? That's 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 take it out of the door to clean it. The short circuit inside is probably by water or dirt.
So now I am very HAPPY!

My problems with locking/ unlocking:
- Happens when the weather is cold and/or moist.
- Central locking doesn't work on the driver's door either with a key or remote.
- I can open all doors with a key in the passenger's door.
- Sometimes I hear a click from the doors, after 5 minutes from a cold start.
My exploring led to this solution:
- I unplugged the driver's door latch plug. All 3 other doors suddenly worked.
- Focus central locking works like this. There 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 get earthed at the SAME time.
- So I used my voltmeter a bit. WTF! Both wires were earned. A SHORT CIRCUIT in my driver's door latch. [ohcrap]
- So I wanted to have a little fun. I unplugged the latch plug-in driver's door. Then I short-circuit these two wires myself to simulate how the car would respond.
- The car responded exactly as described over, but nothing worked. It even made this click sound when i took away the short circuit. Hurray!
