Door Ajar

[albino]

A few weeks ago I was driving and I went around a turn and the door ajar light came on. I figured one of my doors just wasn't shut tightly. Unfortunately that was not the case and now my door ajar light is on/flickering almost all the time while I drive. It is definitely the passenger door sensor that is acting up. I switched the sensor with a decent condition used one and the problem didn't go away. I then switched the passenger sensor with one of the rear sensors that I know works properly...the light was still on. I know that it is the passenger door becuase if I turn the car on I can push/pull on all the doors and the light only turns on/off when I get to the passenger door. Anyone know how the door sensor wiring works? I am assuming I am looking for a bad ground or some bad insulation on the sensor wiring.

Sounds like you may be on the right path, the wire grouding somewhere due to exposed wire would be a good guess.

Second option would be the door hinges have sagged and the door is not fully shutting and closing the switch all the way, so it makes intermittant contact.

You were right on with the second guess. I put a little piece of adhesive backed foam pad on the door where it comes into contact with the sensor and now the sensor is getting compressed enough. Thanks for the help.
