does anyone know where to get the individual switches to repair the five position acc (gen. three, horizontal switch row) controller?
Specifically, for the 123.

You can get replacement "plastic face plate buttons" from the dealer AND they are relatively reasonable. The actual switches inside the controller are a different issue. The controller typically needs to be opened up and the solder joints "resoldered". Are you sure the switches are bad?

In the disassembly process, the off position and normal a/c position swithches were damaged. The unit will work, but it runs as if the middle button were pushed in all the time (until another button is held or pushed in). The two buttons no longer release the other switches by pushing another button, and they do not lock in the on position.
