i have a s reg focus which has electric issues when its cold and wet. it has problems with central locking not working, horn not working and washer jets. in the summer everything works properly. anyone else had these problems? this morning i started it closed the drivers door and it locked itself, had to get the AA out to open the car.

 

My central locking in my frs plays up a bit when its really cold mate not got to the bottom of it yet

 

Sounds like it could be a corroded connection some where.Our fords dont like cold weather.

 

even when it lives in the garage it still plays up when its cold, had plenty of old fords but never one this bad!

 

I would be checking the fuse box behind the glove box and i would be checking electric connections.
