01 LeSabre Three windows and door locks dont work
 
My locks and doors stopped working one at a time over the past few months until all i had was the drivers door that still worked.
The power seems to have left the passenger front door completely since even the buttons on the door have no lights in them.I read in a post that there is a connection under the drivers seat that corrodes so i l took front seat out and lifted carpet. It was wet under the carpet and located that connection. It was corroded so i cut and re spliced wires now the rear passenger side window and lock works again. But the other two doors still do nothing.
I've checked voltage on the two tan/wht wires and one is 11.7 and the other is 8.5 is this normal or is it indicating a bad ground? Also does anyone know if these two wires control only the back doors or does it control all three doors?
I've got this car torn apart and can't find why it still has two doors not operating. I'm at a dead end right now and kind of frustrated.
Any other help or suggestions much appreciated
Thanks in advance.

Well i've been doing some electrical testing. So far i've determined that that all four doors have power to them on the main plug that each has a good ground and that the tan/wht wire is a complete circuit. But i don't know and here is the big question?
Can the Driver door module go bad where only certain doors quit working?
Or if there is power to a none working door is it that door module that is bad?
Don't want to start throwing parts at this so i'm looking for some help.

Ended up being the scotch connector under the drivers seat. They had corroded so bad they lost connection.
