Hi, folks.

My H reg Ford Fiesta, which itself is running fine, has just developed a problem with the driver's sidefoor lock. The door won't grip closed when you shut it.

I've taken the side panel off the door, and all the parts seems to be moving when I use the inside and outside door handles. Everything moves when the key turns, too, so it seems it must be something that's gone inside the lock unit itself inside the door. The oblong unit, if you know what I mean.

I've tried the local scrapyards for spares, but they have nothing. Is it possible to repair this locking unit at all - it looks quite sealed - or has it given up the ghost?

Many thanks for any help or advise anyone can give.
