I have a 1980 corvette and had several wiper-related issues but got all the issues fixed except the wiper switch.
I bench tested the switch and proved bad so I opened it up and cleaned it and re-assembled it according to Willcox instructions but still didn't work (only washer worked). I then ordered a new switch ($83) and it didn't work, not even the washer function which at least worked on the previous switch. I opened up the new switch and found the washer didn't work because the stem which pushes out the center contact was too short. So I gave up on the old technology in the switch.
and what the final product looks like from driver's view:
So what I have is a rotary switch which supports Park and Low speed but I don't have High speed (I can deal with that).
The switch also supports the washer function via pushing in on the **** like the original switch function and I added an Led bulb like the original switch had.
I believe I paid $12 on-line for the rotary switch which is probably more reliable and I believe fits in quite nice.
It's better to be safe for now......later on you might find a correct replacement with high speed setting
(Did you ohm test each wire to see if there is a bad/corroded connection.....I use the "wiggle method"--car battery disconnected/connect the ohm meter to one wire/slightly wiggle the wiring bundle under the dash and in the engine bay to see if continuity is intermittent for each wire that connects to the wiper switch)
Yep, I tested thoroughly the OEM switches and followed Willcox's papers to the tee. I figure as the years go by, the OEM switches will just get more rare and expensive and now I have something that is better technology and a lot cheaper.

good job, Bubba would have used speaker wire straight to the alternater and put power to the ground lugs. thats how mine melted when i bought the car and tested the wipers
