Open door problems

[dustyroads13]

so my open door lights stay on and caused the alarm to go off and all that stuff.... sure this has been posted a bunch before.
took out the theft ecu cause honestly I just dont care at all about having a theft system but that doesnt get rid of the door light problem and draining the battery.

I disconnected the lights but if its still sending a signal then would it still drain the battery?

I replaced the door sensors and they look fine but both doors make this buzzing noise when they shut like a little motor is going.

Heres the questions
is there a certain part or ecu or wire or fuse I could unplug or cut to just get rid of this problem?
is there another sensor where the door locks onto the metal bar because my doors sag a bit?

I thought it had to do with the theft ecu but I guess not.
probably the lighting and all that but I need some of it so blah

I wish I could strip all this pointless cra pp out of the car.
