OB side mirror switch wiring?
My car came with the drivers side door panel off and wires hanging free. I am working on reinstalling and trying to figure out the electric mirror switch hook up.
The switch has a thumb roller type switch on the bottom and a rocker switch at the top which I assumed switched between left and right. Owners manual does not call out left and right but the rocker is for heated mirror option which I do not know if I have because the option sticker is no longer on the car.
I have a wiring diagram which only shows the left mirror as having a motor. Additionally the wiring does not seem to match what is hanging loose at my door nor does it identify the switch terminals by number and the switch is not numbered either
Switch directional controller has 6 terminals. The rocker switch has three terminals. The door wiring harness has 9 wires (2 for the speaker that do match the wiring diagram).
Car wiring harness has 7 wire connectors, two single connectors with double wires.
1- double Blue/Black
2. double white/white
3. single wire black with violet strip
4. single wire brown
5. single wire brown
6. single wire black
7. single wire blue
Can anyone shed any light?

I expect to be able to supply a confrimed chart of which wire goes where, but not until this weekend!
After a bit of help, taking the mirror transmission apart (it was broken already) and reviewing the detailed current flow chart, I think I finally got it!
The rocker switch has nothing to do with the heat function. That comes on with the rear defroster.
The toggle switch toggles between the left and right motors.
The joystick cleverly makes the circuit to the motor in two ways - reversing polarity.
The other thing it does is makes the circuit to engage a transmission in the mirror to shift the movement from the up and down and the left and right functions.
(To be confirmed and from memory!!!!) If you look at the bottom of the switch with the connectors angled upwards, from top left and going clockwise, I believe connectors are:
1) ground
2) jumper to the toggle switch and on to the black and blue motor wires left and right
3) ground
4) double blue and black motor wire
5) double white wire
6) violet power wire

That's really not very clear the way the owner's manual describes how to enable the passenger mirror heater.
I'll post page 23 of the current flow diagram that you are missing. It was the missing link for me.
The toggle is used to choose the circuit for the left or right mirror motor.
The four way switch has a jumper to the toggle. The toggle then switches between the left and right motors blue and black wires.
I can't recall how the diagram showed the operation of the right hand side mirror heater. But I don't recall it being involved with the toggle or the 4 way switch.

Mirror heat for both mirrors is switched the same way - defroster. The toggle selects between mirrors (L/R) for adjustment simple as that...
In the switch diagram the 2 SPDT switches on the left side control the motor direct - they just act as a reversing switch. For up the motor runs one way for down it runs the other, for left the motor runs one way for right it runs the other. A motor gear mechanism solenoid is controlled by the right most switch which is active for one plane (L/R vs U/D) only to provide the plane selection for the movement.
See another thread recently to see which connection is which.

You entirely missinterpret what they are saying. The fact that they call it adjustment for the heated mirror is confusing you - the focus is on the adjustment not on the heated - heated is just part of the overall mirror description.

I did read your post in Dan's other postr but I did not see reference to the rocker switch which if I am tracking correctly now selects right or left mirror. Did I miss that?

And that is what your missing current flow diagram page shows. That's what made it all make sense to me.
I assumed the rocker switch controlled switching power to the 4 way switch. It does not.

The rocker switch controls which motor (L/R mirror) the output of the left most SPDT switch feeds to (switch pin 3) - the options are left mirror motor or right mirror motor - its a very simple circuit and is all that is required to be different between a single mirror config (most 77-79) and a dual mirror config (80-86).
Both L/R solenoids are fed at the same time, the only thing that causes mirror movement is the motor....

Damn. I documented this last time I went through this and I thought I had posted it here. But I cannot find it in my list of posts, so either it did not or posts do not stay around forever. I still have it documented in a notebook in the convertable, but it is at home.

My switch was in a spare parts box and door panel off when I got the 928. It may not be the original and I have not pulled the right door panel to see if I have wires running to the mirror.

Ok here is what I have in my notes. This diagram is with you sitting in the driver seat, the switch out, and upside down so you can see the wires.

Sorry about all the periods. I drafted with spaces and it was more clear by they seem to go away when posted.
From looking at your picture I think your joystick might be installed 90 degrees out from where mine is and your switch 180 out.
Let me know if this does not work for you. These notes are several years old and might be in error. I could re-check.

My notes were based on the wiring diagrams. I know some early cars had only a drivers side mirror - but the wiring diagrams show only one sided wiring for 77-79.. I have seen some early cars with 2 mirrors so it seems they certainly exisit - in which case if they are electric the wiring is as shown for 80-86. Even in '80 the second power mirror was shown as optional.

Well it is also possible they have 2 mirrors but only one is electrically controlled - however logically it would be more useful to have electric control on the passenger mirror only if thet were the case...
