Good evening,
About this time last year, I had problems with the front off side door of my 60 plate Mondeo not locking. The car did not give any indication that it was not locked. I heard the locks clunk and the lights flashed, but if I pulled the handle the door would open; some times it would set off the alarm, other times it would not, which was concerning.
I thought perhaps the lock in that door needed changing but then I found that the rear near side door was not locking. Later that door was damaged and my insurer had the door repaired and the lock was changed.
The driver's door stopped playing up at that time; could it be that the driver's door only locks when all the other are locked? Was it not locking because the r/n/s door was not locked?
I also noticed that this behaviour only happened when it was cold, so perhaps it stopped because the weather warmed up?
Anyway, now it's winter again, the driver's door is playing up again by not locking. It is only intermittent, so I worry if it goes in, it won't play up and no fault will be found.
I notice that the f/n/s door does not completely unlock when I press the remote control: I have to move the tab on the door to let the passenger it; it only seems to have moved half of its travel. Is it likely all the locks would wear our at the same time?
Do you think that I should change the passenger lock or the driver's lock? I don't really want to pay to change both. I think they cost over £100 each and I worry what if I change them and the fault is not in the lock but say electrical; that's a lot of money to have wasted.
What do you think?
Thanks, Stephen.
