1)The outside rear-view mirrors' control doesn't operate the mirrors in any direction:left, right, up, or down;
2) The door remote only operates the drivers side door ( and not all the time);
3) The inside button only opens/locks the driver's side door.

Some time ago the outside, right hand, rear-view mirror had to be replaced due to an accident, but I do not quite remember if the problems began afterward.

Where can I get an electrical schematic diagram?

 

Check "that auction site". I got a full service manual with schematics there for a good price.

 

my truck has the same problem with the passenger side lock

 

does your mirror try and move at all? cause mine wants to just doesnt go in any direction. it almost rotates.

 

Mine does the same thing. I've been told there is corosion in the switch and it is a common problem for our trucks. Open the switch and clean the contacts or replace it all together. I'm skeptical because it looks like it wants to move but just kinda clicks back and forth.
