I own a year 2000 ford focus, the speedometer doesn't work along with the mileage counter, but all other dash needles and lights are working fine? Also the central locking seems to be abit tempermental, 8 times outa 10 it will lock all doors then automatically unlock all doors immediately? same thing happens if manually locked by key in drivers door. only way to lock all doors is to use key in passenger door lock. I make sure after locking, that all doors are secure before going inside my house, but recently, i have been going to unlock doors with key fob in the mornings (unlocking never seems to be a problem) and the doors are already unlocked??? is the locking system failing through the night and controling its self??? This is starting to get very frustrating and i can never be sure if my car is secure. If someone is able to help with my problem i would be much appreciated.
