Electric mirrors.

Two separate switches are used. One (double throw double pole) switches from the left and right mirror, and one 5 pin joystick moves it around. The wiring diagram was a bit confusing, so I coloured it.

The colors are random,
Purple = Positive
Brown = Negative 
They are the inputs, that the joystick (Mirror Switch) distributes to the motors. The joystick also has to change the polarity of the outputs, so the motors can move in the other direction. There are only two motors per mirror. Obviously, one for vertical, and the other for horizontal movement.

The DPDT switch was easily tested, and it was fine.
The problem is deffinitely the joystick switch.

So.. pins 2 (12v) and 4 (Ground) always need to be present. Pin 3 is common to all motors, which leaves pins 1 and 5 that are are the controls to their individual axis on a motor.

Based on the above logic:
1&2 and 3&4 move the mirror up
to move it in the opposite direction we reverse polarity so..
1&4 and 3&2  move the mirror down
And the other axis:
3&2 and 5&4 move the mirror left
3&4 and 5&2 move the mirror right

Tested the mirrors by jumping the pins where the joystick connects, and all looks to be fine.
My options are replacement of the joystick with a new unit for almost $100, or manufacturing something that involves 4 momentary DPDT switches. The latter will not fit in its original location so I would have to hide my non OEM shame in a different location. The third and most logical solution is to buy a used one.
