on my 3dr i have no central locking at all, its as there's no power to any lock.

is ther a fuse, relay or module that controls it?

 

the relay module is up on the passanger foot well just about leval with the ashtry
Two plgs go into it do you have a alarm that opens the car ?

 

from Haynes manual :



where :
14, 19, 17 : motors in doors and tailgate
18 : central locking relay
113 : tailgate release relay

 

cheers i will take a look

i have a after market alarm fitted which opens the drivers door but thats only because its had a aftermarket motor fitted to do so.
but if the origanal central locking worked it would open all locks

 

thanks for that mate

is 18 the module thats in the passager side foot well?

 

The 3dr central locking is very basic and only operates from the drivers door, which is why aftermarket alarms have to add the seperate actuator to the drivers door in order for the doors to lock, so the gubbins in there should be your first port of call to clean/replace to get the system working again.

On the mk2 sierra/saff it worked off all the doors

 

whats the gubbins? is that in the drives door?

 

LOL he means the electronic "Gubbins" in the drivers door, such as relays etc that have been added with the alarm.

I would first start by checking the fuse as this is easy to do and where you need to make sure the circuit has power.

I guess 3DR'S have a "in car release" for the tailgate then by looking at that diagram?

My xr4i had a seperate hatch release, but my mk1 2.0GL operated from both front doors, pretty sure, I would look around the drivers kick panel area to find where the wires from the alarm for the lock unlock pulse have been joined into loom from door, after checking fuse if both lock unlock don't work.

Just to clarify.

on the 3dr cosworth the central locking is managed only from the drivers door lock, if you open the passenger door or hatch with a key it does not activate the central locking.

Therefore if the Ford actuator in the drivers door is not working then the entire central locking system does not work. Alarms fitted to 3drs that also operate the central locking from the alarm fob use a stand alone actuator which sits in the drivers door and connect to the locking rods, when the fob is activated the stand alone solonoid pulls the rods which in turn then activate the ford solonoid which then operates the central locking, so the Ford solonoid is the first thing to check after basic checks on fuses etc. Put some direct power into it and see if it activates, if it does not then there is the problem, if it does then start checking along the loom back to the control boxes behind the glove box.

The 3dr does not have an in car operation for the rear hatch.

Hope that helps

 

cheers paul

i will give it a try and see what happens

 

just had a look at my drivers door lock and if does'nt have a actuator/motor, it has, what looks like a switch.

so i tested it with my multimeter and it seems ok.

 

is this the module? number 18 in the diagram?

 

thats the bit I meant sorry, coudnt think of the right name for it, that activates the central locking control box which then power up the actuators on the passenger door and rear hatch.

That doesnt look like the module that I remember, thought it had a triangular type mounting plate behind it

 

where will the fuse be for the central locking system?

 

In the fusebox (No 10) it's 20A it also protects the interior lights, clock and power mirrors this is for MK2 so yours could be different.

i have not got power. it was a fault with the electric mirror wiring.
i don't know why but there's a sub loom for the electric mirrors in the drivers door. this has to be plugged in to get the central locking working.

my boot lock works perfect but the passagerside door won't lock, it trys to but it seems it does'nt have enough power move the lock.
if i lock it with the button it will open ok.
also if i but direct power to the acuator it will lock and open fine but won't buy using the drivers door switch.
there can't be anything wrong with the drivers door switch as its working the boot lock ok.

any idea's?

 

Hi All,

the removed pic from haynes manual can some one post this back ?

My 3 dr is opening from driver side but not locking on passenger side ( sloenoid is trying but not getting there )

Prevouis owner welded the door locks and though the tailgate would be also a master but as I read here only drivers door.

To mount an aftermarket system I assume I need to use the drivers door as a master.

Were do I need to mount the cables for the signals on the solenoid cables ?
