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?

From what you said that you only have 2 connections on your wiper motor it appears you have a one speed motor installed (see picture below for difference between motors). If you have all the wiring and switch for a two speed wiper system you will need a two speed wiper motor.

If you have a two speed wiper motor make sure its wired to my post on page 22 post#527 http://67-72chevytrucks.com/vboard/s...318544&page=22
