Factory Alarm going wacky (door is ajar)

[jeveng]

I have a 2003 gmc sierra z71 with 92km My alarm automatically goes off and while driving the door ajar message comes on with all the inside dome lights coming on. Sometimes the locks open and close automatically while driving. I have unhooked the battery for 1 night no change. I also have put the key in the drivers side door to try to reset the problem but nothing works. I need help please.


Thanks
