weird wiper switch on my 67 cuda.

[moparmat2000]

hi Y'all,

i started dissassembling and cleaning up the switchgear for my restoration. i use a solution called alumiprep ro remove the tarnish off the copper and brass contacts, and restore old switches to useable condition. anyway i took apart my windshield wiper switch assembly. it was so crusty it wouldent even turn. i cleaned all the old dilectric grease out, scrubbed out all the grime, used my alumiprep and a small brass bristle brush to clean everything up , then i applied new dialectric grease on the contacts and reassembled. there appears to be only 1 detent on the switch, then its a variable knob all the way to high speed.

heres the question. did the 67 barracuda come with a true variable speed wiper switch?? not a low, high switch with detents, but a true variable speed switch like a rheostat?? i ohmed it out with my meter, i smoothly vary vary the reading by rotating the switch from first detent to full high.

is this correct?

2 speed was standard...continuously variable speed was an option.

part number 2770378 is the 67 variable switch and is a full rheostat. I will say though there is not a huge difference in the speed from one end of the sweep to the other.

Again my memory aint great... Should be 3 resistor wires on the outside of a 90 degree gear motor. ( You may find their insulation broken. Doesn't matter so long as they stay separate and dry. I was told that insulation contains asbestos. Don't know if that is true. They do get very hot.)
From off position the switch slides through a variable low speed until it end of range/travel which is the fixed medium speed. Then there is a detent click to high speed. Thus described as variable 3 speed.
