I have the GM diagnostic CDs

The diagram are different depending on the car it came from, so if you give me that I can give you a diagram of it.

I have fooled around with these. They run off grounds. The switch itself must be grounded. The high/low speed are also grounds that go out to the motor.

Not sure what you are wanting to do, but I have found you can use a late model column switch and run it to ground instead of power (as the late models us a power signal to trip the motor) and it will control and old wiper motor.

What I could use is the switch operation of a 86 Buick column wiper switch and a 80 buick dash mount.

Trying to get a dash switch (ground pulse) to work in a column switch car (power switch).

I got everything to work but the park mode so that it pulls the wiper down under the hood. I think it's tied into somehow the washer motor but I can't be sure................damn GM :) why couldn't they just stick with ground pulses......
