I've had that happen in my 2002 mountaineer. what I've found is that if you spray the door latches with wd40 it will clean off the sensors and the door ajar light should go out. but make sure all the doors are shut.
Hearing a rubbing noise while driving a 2002 Mercury Mountaineer could indicate several issues, such as worn brake pads that are making contact with the rotor, problems with the wheel bearings, or issues with the suspension components. It could also be caused by debris caught in the wheel well or a misalignment. It's important to have the vehicle inspected by a mechanic to diagnose the issue accurately and prevent further damage.
The alarm may go off while driving your Kia due to an electrical shortage. This may also be due to a blown fuse.
The alarm should turn off once you start the car. If the alarm is going off while you are driving, pull over and remove the fuse.
Does it happen only while the car is "off" or does it also happen while driving? If the alarm happens without any apparent reason, even while driving, you may want to check the anti-theft relay. If alarm happens while the car is off, it could be a problem with any of the various switches and sensors that sense alarm conditions.
It sounds like you need a new serpentine fan belt.
Check your hood alignment sensor for the alarm and the trunk sensor
why does my door ajar alarm keep coming on and off while driving my car.
It could be your remote that is faulty and while in motion it can activate. I had that problem. If not, you have a short somewhere in the wiring.
Get out unlock the door with the key. Then get back it and try it
Maybe a possible factory alarm problem !!

There is no reset. If the alarm goes off while driving and you are buckled in, you need to check the wires going to the seat belt buckle.
