I cant seem to find anything online, or a FSM for 72 and newer. Does anyone know the test procedure? I believe test procedures are specific to the switch. eg, test procedures from 69FSM wont work on a 72 switch.
Its a 3 spd with washer if that helps.
Thanks
Steve

Well, I might have found some info. Posted on Passion4mopars website. I know the reviews are horrific with the scamming/crack problems.
Sidenote, I must have checked approx 5 Factory parts manuals, and NONE have this part number(3488764). Not sure if its a superseded number or not. Any testing/troubleshooting mentions a "B/U" terminal which this one DOESNT have, so makes it difficult to test.
Here's closest I have found, even though it mentions "B/U" terminal, it states "no connection"
My 6 wires
A=Brown/tracer
B= Pink
P=Blue
W=Brown
F1=Red
F2=Green

B terminal is usually battery. A B/U terminal? A lot of wiper switches did have a unused battery terminal. Those installing cb radios, etc.. would use it for power source if/when they knew it was there. So I guess my question is do you find the B/U terminal involved in switch testing procedures?
 
Thanks Ben, I've looked thru 3 or 4 FSM and they all mention "B/U' terminal in the testing. (Except the Passion link above) As mentioned I as of yet have to find one parts manual that has this # listed....

It is really frustrating that the factory diagrams do not show you internal contacts of the switches. It drive me nuts when troubleshooting something. You have to reverse engineer how you think the switch should work.
