Hello can someone please help, car alarm keeps going off seems the cause is the drivers door for a split second tells the car it has been open yet its locked. I have so far disconnected the micro switch on drivers door lock so tells car door permanently closed position, yet when it rains alarm goes off and watched car in rain and see on maxi dot the drivers door open and close for a second so if not the micro switch im guessing a ground issue.

 

Any one had this same problem and fixed it.

I'd start checking the wiring in the door opening - see if any of the cables are frayed.
