I have issues with my single motor, cable operated wipers with 2 speed rotating combo push for washer switch on my 69 2A. (sounds more complicated than it is - switch with knob that turns 1 or 2 clicks clockwise for wipers, push for a squirt of washer aimed mostly straight up in the air).
Before all motion ceased, my wipers would work OK on one speed only and stop wherever they happened to be when turning off the switch. The push for washer action also worked - that's a separate microswitch on the back end of the shaft.
One day while trying to remove some birdcrap off the drivers windscreen I alternated between squirts of fluid and turning the washers on and off. At some point the wipers refused to work and I was left with a streaky splotch of white in the middle of my field of view surrounded by drops of washer fluid.
Knowing (or thinking) my switch was dodgy (one speed only) I figured that was the best place to start. I ordered a replacement switch and was able to get a NOS in original box.
So it came and I carefully swapped wires from the old switch to the new - one by one so as to preserve the correct order. I think one of the wires is a "park" function that brings the wiper blades back to bottom when the motor is turned off - just not sure which one does that - the blue wire or the red/green wire. My money's on blue.
No worky.
I broke out the multimeter and got 12v at the green wire into the switch. Checked green from the switch to the motor and got 12v there as well.
Ran a wire with 12v directly to the brown/green terminal on the motor - wipers work. Motor good (at least at one speed) and by inference, ground is good.
Checked for voltage on all 3 of the remaining terminals on the rotary switch as I rotated the switch - nothing. All terminals were cleaned and shiny. Still no worky.
Am I missing something? It's a dead switch right?
