Anyone know how?I dont have a factory harness in my car and the one that is in there has no provision in it for wipers.Has a Brown,red,green and blue wires that go into the wiper motor.I just would like to hook it up with a toggle for now.I can deal with not having the auto park and other speeds.
 
them wires go to a step resistor. high speed the motor recieves 12 v straight. med current goes through more of the resistor which lower voltage to around 10 or so and low goes through all of the resistor which lowers voltage to around 8 or so. i beleive the motor recieves ground through the mounting bolts. im pretty sure on this but am not positive about the ground. someone here will conform it.
 
I rebuild those and I have a switch that I made a jumper harness for to attach to the motor for testing purposes. Real simple to do if you have a switch and a wiring diagram.
 
Got the wiring diagram to test it off another site.Turns out it is junk.
 
Hey Topher- You rebuild wiper motors? I have a 2 speed that works fine except it won't park. It stops as soon as the switch is shut off. I tested it using the service manual instructions, which says to replace the motor assembly. Seems a shame if the motor works. Is it possible to repair this?
