Hey guys, I'm having a problem with my 2010 mazda3 hatchback. While driving, occasionally the "door ajar" light turns randomly on and off and according to the display, the faulty door is the front passenger door. My question is where in the door can the problem lie? There is no button on the door that comes into contact with the body so I'm guessing the sensor is part of the entire lock assembly. It happens so randomly that I have to leave the center dome light permanently off as it has turned on in the middle of the night before due to the car suddenly thinking the door is open. What do you guys think? Any help will be greatly appreciated as it is no longer under warranty so I will have to purchase/install any parts by myself.
