67 windshield wiper motor and harness

[knahavasu]

i have a 67 dart and am in need of the windshield wiper harness ??

also need the wiper motor or a recommendation who can rebuild a windshield wiper motor ??

Thanks

@ns1rm21 I believe knows someone. There is a member here. Switch has to match motor. 2spd/2spd and 3 with 3.

Post photos of your motor. and the part number on it. Also the cars build date from the fender tag or build sheet. The 2 speed harness is part of the motor assembly. It does not come off without cutting wires.

What did we come with? 3 or was it 4 possible motors for 67?

It is a 2 speed motor

There are 2 - 2 speed motors used in 67.

Looks like you just need the plug? That and maybe chk the hot spot on the wht plastic piece?
FSM will show where those 3 wires go.

Remember the FSM diagram shows the 4 wire motor so one of the cavities is blank.
The brown spot is pretty typical. It might be residue from grease or something.
I agree it just needs the correct connector and termnals. Wrap the bundle in tape and it should be good to go unless there is an internal problem.

I think we determined that's the Leece-Neville motor. For sure it will wire up with a two speed switch.
It visually looks good. No one specializes in them that I know of. What's wrong with it?

I'll link to the group effort wiring diagrams in minute.
The "white plate" motor we beleive was made by Leece Neville

Lets update the list since more examples and details have been emerging:
2822 930: Redfish: Variable speed. Green, Red, Blue, Brown at connector
2770 137?: 4spdragtop: Variable speed with variable speed switch; 3 wires atconnector
2822 962 : xtremist: Variable speed ? with variable speed switch; 3 wires at connector
2822 962 : Cuda Al, JCWren, Dana67: Variable speed with two speed switch 2820525; Red, Blue, Brown at connector. SPD 11/66
2822 963 : Cuda Al, Mattax, Dana67: 2 speed, white switch plate, 2 speed switch 2820525; Red, Blue, Brown at connector. SPD 12/16/66, 2/67

2822...

D is empty. If the car had a mnual transmission, then cavity H is used for the reverse light switch. Other wise it is also empty

Cleaned it up now that the reverse switch question has been addressed.

and here is one version of the two speed wiring.

I still need to verify the passenger compartment.

Oddly, for 67 the electric washer feed goes to the middle connector.

 

[knahavasu]

Slow speed runs for a minute or two then stops, fast speed seems to run fine. I put 12 volts to it to test without the switch.

My diagram shows it as a 4 wire, G,R,and blue….diagram shows a Green wire that is not present.

Switch has Green wire to Bulkhead

Bulkhead connector is 4 wire.

New dash harness

I put 12 volts to test it

If you post which wires the 12 Volts were connected to maybe I can help narrow it down.

Otherwise you'll have to wait for one of the guys who knows these a little bit.
It may be something just needs a little cleaning, or it may be the switch is needed. In the meantime let me see what I figured out the last time.

Righto. The wiper switch has a resistor on it. So it has to be used to get both high and low.

The 67 shop manual says to bench test the "two speed motor," connect the ground to the ground strap, and connect the "black and red" which for these motors must be the "brown and red" wires to the positive power source.

Here is my understanding of how this motor works

On the switch
Terminal B is power in. Terminal B/U is power out to the back up light switch. These two are connected to each other all the time.

With switch off.
Park is connected to Power (B)
When the power is shut off, the blue wire keeps it running until the switch on the motor's gear opens.

With switch in low.
The motor's Armature and Field both get full power from the switch.

With switch in high
The motor's Armature gets full power and Field gets power through the resistor.

So if this is correct then the test for the motor is to provide 12 to 14 volt power to both the brown and red wires. Then disconnect them and provide power to the blue wire to return it to park.

The ground to compete the circuit is through the copper strap as you have it mounted.

Hopefully someone who knows these better will chime in.
@Vaanth or @townsend might

Power to Red
Ground to Brown = high speed with continuous run

Power to Blue
Ground to brown = slow runs for a minute then stops

I’ll have to find a bulkhead connector to run through the switch

Still don’t understand the green wire

 

[Mattax]

Still don’t understand the green wire

its for a different motor. See the link posted earlier where we try to figure out all the motors used in '67 B-bodies.

That's pretty easy to find. For the Chrysler type terminals, there is thread devoted to where to get the ones that will work.

Power to Red
Ground to Brown = high speed with continuous run

Power to Blue
Ground to brown = slow runs for a minute then stops

I think that's wrong. I think Brown powers the windings in the armature and red powers the field windings.
Blue wire goes to the switch on the drive gear so its supposed to stop.

 

[knahavasu]

All good stuff..I can get the missing connector, pin it and install it then test it through the switch

I was just trying to bench test it. I think it works.

Thanks for all your help

Your motor is the later version, ie post November. And the more attractive of the two!

This motor uses a friction park. Dry window and the wiper will stop higher on the windshield, wet window and it stops lower.

Basically the blue wire has a continuous feed to the motor but there is a cam and a switch behind the white cover. Once the wiper switch is turned completely off, the blue wire continues to provide power to the motor on the yellow wire till the cam operated switch opens and kills the power to the yellow and the motor.

 

[Mattax]

let see if we can confirm that theory
Could also be which plant made the car?

@knahavasu Next time you're by the car, can you check the numbers on the motor and tell us what the last number is?
The first two should be the same as in my photo, part number, and vender number.
The last number is the date of manufacture.

If you're so inclined. The car's fender tage will have the scheduled production date for the car, and manufacturing plant code is in the VIN

67 is an oddball for the wiring on the wiper motor.
Every diagram shows the 68.

This has come up before and I posted the wiring somewhere.

Stand by.

 

[matthon]

Wiper switch contains the circuit breaker for the reverse lights.

Diagram attached is 68 up, supposed to be 67 up but it is incorrect for 67 as it has 4 wires going to the wiper motor.

From the switch are:
DK Green - to motor
Red - to motor
DK Blue - to motor
Brown - to motor
Brown TR - to washer
White - to backup light switch, yes, on the tranny, it then goes to the backup lights

The wiring at the bulkhead to the motor is short 1 wire:
Empty (s/b DK Green)
Red - to motor cylinder
DK Blue - to motor, the top
Brown - spliced, one wire sent to the cylinder, one to the top of the motor

Yes. It was used in '67. I think was Redfish who posted a 4 wire motor in our thread on '67 wiper wiring.
I'm going to bump that thread soon. I think there were just two options, 2 speed, and variable. But in manufacturing they used two different suppliers for each.

 

[knahavasu]

Thank for all the help

 

[Mattax]

In the other thread I think we were able to conclude that both two speed motors use just the three wires. So the bottom line is the three wires off your wiper motor go in the cavities shown in diagram. The fourth is left empty.
