I need some help, if possible. I have a 1967 C10 long bed that my grandfather bought new. It has been "adapted" several times. ie...farm truck, tow truck (to pull a drag boat) and hopefully now a dependable eye catching occasional driver.
My current problem is the high speed of the wiper motor. I have a 3 wire switch which is good(by replacement and testing). The 3wires are LB, DB Black. Without removing the wiper/washer assembly the only connections I can find are 2 yellow/light blue as pictured else where in this forum.
The low speed, park, and washer work. Is this truly a 2 speed motor and if so how do I get it to work?
