"Door ajar" message while vehicle is secure. The alarm sounds w/vehicle locked. on 2007 Chevrolet Malibu Maxx

Constant "door ajar" message. Horn blasts while vehicle is off and locked. Also had a problem with battery fully discharging while parked and locked at this same time last year.

The door actuator is either bad or wires to it is bad. Need the correct one found, it will have to be traced. The alarm is activated because the computer recognizes a door is still open.

Thanks, Professor. I noticed a sensor on the hood latch. Is that one tied into thew alarm system?

Yes it should be part of alarm as well. That should say hood open instead of door ajar.
