Question about 2006 Ford Focus ZX3
My power locks will lock from both doors but will not unlock from either door switch. I've checked for continuity on the switch for both doors in both the lock and unlock positions and both are working fine. I also replaced fuse 63 on the CJB(central junction box). Both to no avail. I then checked the switch connector and found that the voltage output for locking was correct but that there was no voltage output for unlocking. So naturally I suspected the circuit. I tried to trace the BK/YE wire, for unlocking, back to the CJB to see if I could determine where it looses voltage. However, once it passes through the wire harness from the door to under the dash, I can't seem to find where the BK/YE meets it's connector on the CJB. None of the wires in the corresponding connector are BK/YE. This leads me to suspect that they are bundled into another colored insulator. I have the Haynes manual but the wiring diagram and troubleshooting section for door locks does not seem indicate that the wire is bundled before reaching it's connector on the CJB. I know I'm missing something here, I just don't know what. I know for sure that I have the right connector on the CJB because when I unplug it, the locking function no longer works. Maybe the unlocking wire is routed to a separate connector on the CJB? The wiring diagrams are not specific enough to indicate this, though. I know this is a topic that comes up often in forums but I haven't found a related thread that has helped me to solve this. Any suggestions would be much appreciated.

Your power door lock switchs are an input to the GEM - genaric electronic module . Watch what an how you test you could short out transistors inside the module . The GEM after receiving an input from a switch will activate the correct door lock . Probably has DTC'S -diagnostic trouble codes stored . Your best bet , take it to a qualified repair shop . http://www.bbbind.com/free_tsb.html Check out wiring diagrams here , free .

1. electrical problems are the hardest one for the cars, houses, apartments and etc.
2. I owned a Union 76 services station and a car stero, CB, TV specialist shop in LA. CA, if I were you, I will go to the junk yard and get a whole set of the wire to put it in, because all the wire connect together, there are many terminals, if you take to the car repaired shop or dealer, it will cost you a lot of money.
3. When you change this kind wire yourself, you have to watch out ;
a. Do not unplug any wire connecters at the same time, it will cause you some confusion.
b. Be sure give the model of your car clear to the junk yard to let them find a right part.
c. If you have the right part, remove your connecter one at a time and or you can write it down every step.
d. It is a big headache, believe me. Maybe you have a better way, because you know your car better than I, I trust you can manage right.
e. watch out the circuit board
Good luck my friend, if you need more help, I like to discuss with you.

I would check and clean any ground connections you find, you say it works but does not have the power, this means amperage to that circut is low

ck if either pass or driver switches will work. the lock actuators are common to be bad, but, if they lock but wont unlock more likely a switch problem.

On a 96' Ford Explorer XLT (like mine) the code is in the trunk of the truck behind
the plastic cover where your tire jack and wrench are! There will be
two plastic knobs that you will have to turn to open and lift it off,
real simple. The code will be on the fender wall, bring paper and pen to
write and will need a flash light so you can see the code clearly.
The code is real close the the plasic and kinda hard to see. Hope this helps! If you dont see the above,then try looking around in that area for a 5 digit code, in the fender well or around the jack, or even around the rear washer bottle. Most people have said its around the jack.
Hope this help (remember comment and rated).
