Ford Fiesta electric windows

How do you know the motors / regulators are good ? Have you tested for power at motors ?

Yes straight supply to them and there was no problem when I put a meter on the motor supply lead and operate the switch I get 12 v but when I connect it to the motor and operate the switch it works the central locking cheers hope you can help

What you could check for damage / breaks is the wiring in rubber sheath , where it passes through from A pillar to inside of door .

Cheers will do

Just tried another switch exactly the same stripped the door again to check the loom looks good baffling

Do you know if you can change the bcm for a second hand one by simply unplugging mine and connecting the replacement

Is it possible to just unplug and fit a second hand bcm unit

If you are getting power at motor plug connections up and down when switch operated and ground / earth it must be a faulty motor . Replacing BCMs usually requires reprogramming .

Took it to a auto electrician this morning and he sorted it turns out the multi plug on the a pillar required cleaning they have wax on them from the factory and this causes problems
