2006 sts door open
 

My key fob works normally, and my doors and trunk all open, just wanted to get that out of the way because i've posted this question elsewhere and people assume there's an issue with the fob.

My issue is that the car will never read that the drivers door is open. I approach the car, pull the handle and all the doors unlock and the drivers door opens. However the light doesn't come on and the memory seat/ steering column doesn't move. Getting out does the same thing, it won't read that the door is open and the auto lock won't activate, occasionally the forgotten key alarm will go off.

If I open the passenger door the light comes on and the drivers seat goes into position, everything functions normally. This happens with both fobs and if I use the key.

So any ideas?
