More fixes for the MR2.
Ever since I got the car the up and down function on the left door mirror didn't work. So recently I bought another mirror with motors and wires thinking it might be wiring or a dead motor in the mirror itself. Plugged it in, pressed the buttons but no go. So that lead me to wires.
Pulled out the trusty USDM wiring diagram and went searching. Found the circuit then tested the applicable wires in the drivers door loom first.
No need to test the ground wire as the left and right function work and both functions are connected to one ground wire. Tested the blue wire, that has continuity so tested the light green wire, this one did not. So this meant there was a broken wire in the drivers door loom in the left side mirror circuit, obviously the light green wire. As most people know by now, SW20 drivers door looms tend to break in the rubber bellow between the door and body.
Next step was to take apart the door card and pulling the loom out of the car body and through the door speaker hole.
Excuse the terrible photos this time. Using my other camera that is worse than most mid range price cellphones.

You have to remove the purple tape to get the bellow off the area where the wires break.

This would be why the circuit never worked. All the other wires look fine though. But I also have just had the inner door light stop working. Looked at the red with white wire I found not to work but no breaks in it. Very odd.

Turns out the pin has corroded in the plug where it hooks into the body loom. So now looking for another plug with this style of pin with wires to fix this problem.

Back to fixing the light green wire for the mirror, run a piece of wire through the bellow to pull the wire back into place as when I pulled the bellow off it took the end of the wire with it. Hook the wire into the little loop I made on the end and pull it back through.

Instead of soldering which can cause the wire to break at the end of the solder joint if moved too much I opted for crimping in a new connector.
After that I taped up bits as required and put the bellow back in place and threaded the loom back through the door and into the body.

What a mess.

You can see that the pin in the middle row on the left is missing. I took it out so I can potentially insert another one and wire it back to the existing wire.
