Ford Fiesta Zetec 2002 1.4l - Central Locking not working - Acesare

Hi.

We had a problem with our 2002 Ford Fiesta Zetec 1.4l on Saturday - the indicators on the driver's side were stuck on and stayed on even with the key removed. We got someone out to look at it who diagnosed an earth problem. After disconnecting and reconnecting all the lights on the drivers side, the problem was solved, but the mechanic had no idea what had caused the problem or how he'd fixed it.

However, ever since this was corrected, the central locking has stopped working properly. The fob doesn't work for either the locks or alarm, but even when you use the key in the driver's door, it will only lock that door, not the other 3. If you manually lock all 4 doors, the key in driver's door will unlock them all, but they won't lock again. We've checked the fuse and it seems fine, we even switched the fuse out but no improvement.

Does anyone have an idea what else we can try? We'd be very grateful for any help you might be able to offer.

Many thanks, Jo

Not too sure an earth problem would cause this.If you are happy that the fuses are ok,then I would disconnect the battery for 5 mins and re-try.Also is the battery up to spec?any low voltage here could cause any issue with the gems unit that controls the cdl system and other functions,including the indicators.

Hi, thanks for your reply, have only just got around to trying this. Unfortunately, disconnecting the battery hasn't made a difference - it was disconnected for some time while we waited for the mechanic to show up.

If there was a problem with the spec of the battery, would there be other symptoms? We've not had any issues apart from the lights and the central locking and the lights have been OK since the mech disconnected them all.
