Wiper motor wiring
« on: December 13, 2018, 13:41:23 »
Hi Gents,
I need some info re the wiper motor plug colour coding and function of each wire.
67 250SL, the wiper motor has a 5 point plug. However the plug on the wiring harness has only 4 wires.
Much appreciated.
Chris

Hi Chris,

That's not correct for sure.
The wiper motor and its plug have only four contacts, not five.
The latter is (AFAIK) the W111C wiper motor.
Not correct for the Pagoda.

There's no difference between the 3 Pagodas regarding wiper mechanism, relay, wiper motor, etc.

My 2 cents...,
you need to find the correct wiper motor.


Best regards,
Achim

Hi,
there are 2 different wiper motors, one 4-pin for W113 and one 5-pin for W111. The 5-pin is a little bit bigger but should work with the 4-pin plug. This motor has one wiper stage more.
The wiring should be:
Pin1: black/purple/white from relais pin 56
Pin2: brown ground
Pin3: black/purple/green from switch
Pin4: black/purple from fuse 2/pin15

Tks Gents,
I have two exact same motors with 5 (male)pins, arranged and numbered as follows,
1.   3.   5. pin is NOT numbered but marked with the grounded sign( upside down T)
2.   4.

The wiper power lead has four wires in a six hole plug.
The wires are very similar to your colour coding, except no purple in any combination and the last one black and red ( not bl+ purp )
You might ask, so what is the problem then?  My problem is that I can only get the motor to run at low speed.. No high speed and no park mode.
Any ideas?
Regards
Chris

Hi,
we have at pin 4 permanent power +12V from fuse 2. At pin 1 we have +12V from the relais. At pin 3 you get the second speed from the switch. Or the other way round: which of your cables provide these power.
You should check if these three work correct.
Pin 2 is ground and very often weak because of corrosion.
Did you check the relais?

TKS Gents,
I found my switching and wiring up the motor is fine but the wiring inside the motor is the problem. Only nr 1 pin and the earth pin turns the motor, 2,3 and 4 are dead.
Thanks for your assistance, much appreciated.
Happy Christmas to you all
Regards

as Wre Already stated:

permanent +12v at pin 4
ground                at pin 2
relais  +12v         at pin 1
then your motor should function  :  if not the inner contacts of the motor might be burnt  see pic.

Hi Chris,

I reread your original post. Apart from having the 5-pin motor, it sounds like someone added a 6-hole female connector on your car. I think all Pagodas normally have a 4-hole female connector, and this would be impossible to mate to a 5-pin motor due to interference between that fifth pin and the connector.

One possible source of confusion for getting the right wires to the right pins is that the pin numbering is not clear. The motor has numbering at the pins (which is different between the 4-pin and 5-pin motors) and the connector has different numbering. See pictures below.

The reason I'm looking at all this is I'm trying to figure out: if you did want to use a 5-pin motor in a Pagoda, what modifications would need to be made; either to the female connector, or to the wiper motor, or both.

I somehow disconnected or crossed the wires at the foot operated washer switch on my W111. Now the wipers do not park properly. I can't figure out what I did any suggestions or wiring diagrams that would show this?

Thanks,

Hi Paul,

Below, I'm attaching the relevant part of the wiring diagram for the wiper motor on a W111, to the best of my knowledge. It comes from the BBB. The wiper motor is number 29, the foot pump is number 30, and the wiper column control is 19. As best as I''ve beem able to figure out, the numbers 1, 2, 3, 4, shown on 29,  are the pin numbers on the motor; and 31 is the ground pin. The wires are labeled with colours that should match what you have in the connector.  br is brown, sw/vi/bl is black/violet/blue, sw/vi/gn is black/violet/green, sw/vi/ws is black/violet/white, and the wire to pin 4 (which goes to fuse 2) is black/violet.

At the foot pump, it looks like you should have four pins and they are labeled pin numbers 1, 2 and 4---it seems like there are two pins labeled 2? Pin 1 should have a black/blue/yellow wire that also goes to pin 2. Pin 2 should have that wire plus a black/violet/pink wire; pin 4 should have a black/violet wire that goes to fuse 2. The second pin 2 should have a black/violet/white wire. I can't check all this because I don't have a W111.

Hopefully, this should help you set up the connector wiring.

All that said, I've hit a roadblock with my project of getting the Pagoda to use a W111 motor. I've been able to get full functionality (start, stop, high and low speed), but not parking. I can't quite figure out how parking is supposed to work relative to the Pagoda motor. On the Pagoda, it's the wire to fuse 2 that does that job, but here, it seems different.

By the way, if you have a W111 owners manual I'd appreciate if you could post the pages that discuss operation of the wipers and foot pump. Also if you have that part of the wiring diagram in the manual, it would be useful if you could post that, so I could confirm the wiring diagram I found in the BBB.

Thanks, Meyer
