Okay here goes I have an '02 Fiesta Ghia and on the dash the door open symbol is showing however all doors are shut the central locking will not engage because the car is telling it a door is open. Has anyone any idea how to sort this out,many thanks.

Hi,I have the mark 6 model and it appears that the offending switch is behind the door card possibly incorporated in the door lock I have no idea which side has the problem. I don't think the boot or bonnet will be causing the problem as they are not linked to the interior light. looks like the door card will have to come off, again I've no idea where all the retaining screws are located.This is a gift for my son (he's 21 soon) and this is a real pain.

Your right in your assumptions.

There is a GEM Diagnostic to check the switches so you can pinpoint the offending door.

It is also possible for it to be a broken wire between the door switch and the GEM so check the wiring and switch out before removing the lock assembly, you will have to remove the door card to get to the wiring though.

Below is the procedure for entering diagnostic mode and I have attached the wiring diagram.

If you want any more info PM me.

Diag mode;

Make sure the wiper stalk is in the OFF position.

Press and hold the Heated REAR Window switch

Turn the ignition switch to position 2

Release the heated rear window switch

Press the heated rear window switch 8 times (within 6 seconds)

You should now be in service mode, most switches connected to the GEM when operated will now sound a tone and flash the indicator lamps.

Open and close the doors to find the offending door switch.

service mode will end after 20 seconds of inactivity.
