My '69 has a new pump in it. I tested the wiring, the test light only lights up the middle terminal with the switch on low and high, it lights up the the left 2 with it in the off position. I checked to make sure the ground was good and even ran a jumper from the ground spade to a good ground. Now the only thing I can think of is the switch, anyone know where to get one? I checked Corvette Central with no luck.
Thanks,
Matt

Eckler's lists it in their catalog...part #A8213 for $59.99. Check and see if they have it in stock.

Dr Rebuild 1014660 $56 in the catalog.

Eckler's sends out a C3-specific mini catalog about twice a year. Just got it yesterday....it's in there.

Thanks Guys!

The wiper switch is a "grounding switch", in another words it doesn't transfer voltage from one blade to another,it just grounds whatever wire blade to close the circuit,I'am looking at a Delco switch off a 73 and it looks like it comes apart,it has a plastic body with three blades, a metal face that has three metal tangs that snap over the body in front,if your switch is like this one take it apart,maybe the contacts are dirty,might save 50 bucks
