We own a 2009 Focus SES and are having trouble with a “driver’s door ajar” warning. Sometimes it does it & sometimes it doesn’t. I can be driving down the road 15 minutes after shutting the door and it’ll start giving me the “ding ding” and the “driver’s door ajar” message in the instrument panel. I looked & looked but can’t find any kind of switch or magnet sensor. Maybe the switch is built into the latch? I’ve opened the door and used a screwdriver to move the latch around but that doesn’t effect the “door ajar” warning… If anyone reading this knows where the driver’s door ajar sensor is in a 2009 Ford Focus SES please let me know. Thank you.
I found the component responsible for the “door adjar” signal. It’s in the door latch and likely needs lube if it’s stuck.
You need to watch this man…
