Low speed is the green wire, high speed is the red wire, and park is the black wire which should be hot all the time the ignition is on. Ground is through the case to the body.

You should be able to supply 12 volts to the red or green, but to both simultaneously or grounding any of the three will probably blow the fuse.

 

Thank you very much Jim.
It seems that I ether did not read my wire diagram correctly, or it wasn't correct. I thought that the wiper motor was grounded back throught the switch.
As is often the case, I was wrong.

I think I understand what I need to do to make it work with my simple on/ off switch.
I hook the Red wire to my switch, the other side of the switch would go to my 12V supply. I would feed the black wire with a constant 12V source.... When I put the switch in the ON position, I should have wipers...
Does that sound correct?

 

Well the fuse is 20 amps but I don't think 15 is too small. I think they would give you a lottle more leeway on that.

Here is a picture of the 3 wire motor, just ignore the toggle switch setup.

 

If the motor is in the park position grounding the black won't blow the fuse, but if it's off park it will, immediately.

Yep, I think you have it figured right.

That's what I get for taking to long finding the picture I want. /ubbthreads/images/graemlins/smile.gif yep, sounds like you got it figured out now.

 

I have an additional question, and I didn't want to complicate my last responce, so I started a new one.

I am wondering if someone can help me out wiring the windshield wiper motor with the new "factory" switch I have.

My new wiper motor has a 3 wire pig-tail on it. There is a connector on the end of the pig tail that connects right to my new switch. (It will only fit one way)...

There are 2 other "connections" on the switch. I had assumed that one was for 12V, and the other was ground.... I was wrong.

Can someone tell me how to hook those other two connectors so that I can use my new switch?

If both of those connectors require a 12V source, can I split the single wire in the painless harness, and feed both, or am I asking for trouble if I do that?

Thanks again.

 

The "other one" is for the windshield Washer pump. Usually a yellow wire. REverse these wires and the wiper only works when the switch is pushed in. /ubbthreads/images/graemlins/smile.gif

I have a picture some place but if you have a continunity meter you can turn your switch to "ON" and see what wiper motor terminal makes contact with the extra terminals. the washer terminal will not make contact with any other post unless you push in on the switch.

Does yours look something like this?

 

Thank you very much John.
That is exactly what my switch looks like, and your insturctions are 100% clear.
Looks like I am going to have windshield wipers again in no time.

Thank you very much for your help.

 

I just went through this and John is dead on the money.

Here is a tip...
When you are installing your new wiper motor, run a ground wire under one of the mounting bolts.
Run that wire back into the dash with the other wires and hook it to a good ground source and you will have a lot less problems with your wipers.
