Is there a relay or something that tells if your door is open or not...ef

I know of the door pins, but my car doesnt make any noises if the keys are left in the ig when you open the door...and the dome light doesnt come on, and the auto seat belts dont move either. I already checked the fuse for the dome light and I thought maybe the seatbelts were bad, but I think it might be that they dont know that the door is open or not

help please

And if it is a relay or fuse, where can i find it?

 

Year? Model? Please move a little to the left. I can't see your car.

Anyway, first thing to check would be the door switch itself.
