ford focus door unlock stopped working

use your key to verify which of the white or yellow ires is lock or unlock then tell me the six colours of your alarm lock wires.

ok, how many motor wires there should be?

2 and they should be WHITE/ black and yellow/black, I can see them in the photo.

OK, I've checked wires, and the first 3 on the green plug are: yellow/black which gives impuls more then 10V on lock and 0.2V on unlock, and the next two are WHITE/ black wires, which act the same - 0.2V on lock and more then 10V on unlock. I'm a bit confused, that it's not 2 but three wires, and two of the three acts identically. As of alarm lock wires, sure I can write down the colors, but not sure if it's important, because it's quite simple, it's 2 identical relays connected - one contact is connected short on idle to another, and when locking it connects to 3rd contact, the other 3 contacts are working the same way only on unlocking. I could draw some diagram how it's done if it would do any help.

OK, the yellow/black and either WHITE/ black, it shouldn't matter. I'd be grateful if you could print the wires and their colours and what the alarm says or else the make of alarm. They should be listed as follows: Lock common. Lock normally closed (NC). Lock normally open (NO). Same for unlock.

Ok, I get it, these are the wires of alarm: black: lock normally closed (NC) green: lock common pink: lock normally open (NO) white: unlock normally closed (NC) violet: unlock common orange: unlock normally open (NO)

OK; cut car's yellow/black, black to GEM box side, green to car side, pink and orange shared 15amp (20amp if 4 door) fused to 12V+ constant. cut BOTH WHITE/ blacks. The GEM box side of one, unused. Then, white to remaining GEM box side. Violet to BOTH remaining car side WHITE/ blacks. OR connect to one, then branch out to a relay from the violet terminal 86, 85 to ground. Unused GRM box side to 87a, then from the fused side of the pink and orange connect to 87, join 30 to the other WHITE/ black. Also diode across 85 and 86, type 1N4004, band towards 86 (solder to the base of the pins). This method is safer, doesn't interfere with the car's electrics. This should restore lock control and should still give you key or factory remote control .

ok, thanks for the advice! I've made some drawing to see if I understand it correctly. Is it correct? I'm nor sure about diode polarity. Also I wonder, what if factory remote control will be used, won't it switch relay I'll add? And if unlocking the way it's connected now works ok, maybe it would be enough just to change wiring for locking, only these three wires - green, black and pink?

Yes, just use the lock side on the yellow/black. The way it's wired won't affect the factory wiring.

well, I've tried to connect lock part as you've suggested, leaving unlock the way it was, and now lock/unlock works perfectly! :) thanks you a lot, you've saved me many hours which I'd spend looking for solution :) Thanks! :)
