Driver door ajar, memory seats, power mirrors

I bought this off a private owner the other day. It is running fine, but have these minor problems I cannot figure out.

1. Driver door always is ajar. I opened the door and put a paper clip in the door ajar connector and it still said "driver door ajar" so it should be the switch I would think.

2. Memory seats which are programmed for previous owner work when we put the key in, however the memory seat buttons do not work so I cannot re-program the settings.

3. Power mirrors move to pre-programmed positions when the key is inserted but the dial will not let me move them so I have to move them where I need them by hand.

I was wondering if the door ajar problem makes the memory buttons and power mirrors not work either. But I assumed maybe there is a broken wire somewhere but I have tracked it everywhere I can think to look in the door hinge area, in the door itself, under the dash, I do not see anything jumping out at me that it is broke, they all look good?
