Wiper motor and help wiring it...

This help at all?

I'm assuming the aftermarket relay you're using has the terminals labeled, since the vw didn't have a wiper relay.

 4 wires= low, fast, park and ground

This car had 5 relays under the dash... Two were plugged in. The headlight and maybe one more. We gutted it and tool out all of them. I'm reusing the headlight relay. So does the wiper motor not have relays? My buddy removed that part of it. So we don't recall how it went in. It was such a mess trying to label stuff wasn't an option. So we are starting from scratch. Thanks guys!!!!

I don't have a green wire. Wonder if that's my " brown" wire?? Thanks for the help guys. I've gathered that the wiper motor has no relay... That's strange, as that motor should draw a lot of amps!!

shows (same as i posted before):

 

31b (park switched ground): brown

53a (park power): black/violet

53 (low): black

53b (high): black/yellow or black/white

 

separate ground on wiper motor: 31: brown

 

later ones had a relay for intermittent wiper function. They used a green wire on wiper terminal 53e. http://www.thesamba.com/vw/for...hp?p=6254055#6254055 and the switch is wired differently between the two.

Ok... So here is the question... why am I missing a brown on the wiper motor? I can certainly add one and wore it as shown.. Thanks for the diagram and the help. I appreciate it. I wonder if I have a 5th, thats just a ground already grounded way up in the dash... perhaps I overlooked that. Thanks again. Keith

Maybe the missing wire is for the "park" circuit. Basically, with the ignition switch "on" you should have 12v. to the wiper switch....one pole on the switch for "low" speed wire and one pole for "hi" speed. The "park" wire can share the pole that feeds 12v. at the switch. The "park" circuit should be hot when the ignition switch is on to park the wipers when you turn the wiper switch to the Off position.

Ok excellent. I know the motor worked prior to gutting the electronics. However I never used them! I have no idea if they were two speed or even park. For some reason I recall messing with the switch to get them as low as podsible, as if park wasn't hooked up. I hope the motor is labeled in correspondence with the switch.

If that set up is from a '71 Super, it had 2-speed wipers.

Ok thanks.

Ok... Back under the dash today... Ah ha!! Some ass cut a green wire even with the end of the insulation sheath. Hmmm. So I see black/ grey, black / yellow, black, brown, and of course this newly discovered green wire that's been flush cut.

Green wire implies it's a wiper motor for a column switch. They probably cut that park wire because they tried to wire it to an earlier dash switch and kept blowing fuses.

 

Assuming you don't have the late column switch or some sort of universal dash switch with 53e terminal, try this to connect a late wiper motor to an early vw dash switch:

 

Using just the dash switch and swapping wires won't work because the early switch's 31 terminal is grounded. You'll have to use an extra relay to make the park function work. On each line below I've labeled the two terminals to connect, the --- indicates the wire connecting them. I've labeled your motor wiring colors as well.

 

switch 53a --- motor 53a (black/grey)

switch 53 --- motor 53 (black)

switch 53b --- motor 53b (black/yellow)

switch 30 --- +12V

switch 31 --- Ground

 

motor 31 (brown) --- Ground

 

relay 86 --- +12V (or to switch 30)

relay 85 --- switch 31b

relay 30 --- switch 53

relay 87 --- motor 53e (green)

Here is what I am trying to wire up to a stock 71 wiper switch... Thanks guys

Justin, did not see your reply until now... Thank You so much. Keith

WHat is the second wiring? Is that for use with a relay? Otherwise, I won't use a relay with your first suggestion right???

 

I am not 100% sure if your reply was for 2 different ways???

 

And I should also mention that the relay's +12V source needs to be switched (turned on by the ignition switch) not connected to constant power. The relay is energized in the park position and I don't want to drain your battery when the car is sitting. Though you can connect both +12v connections to a switched source if you want.

There's not two different wiring setups there, just one. I just separated the devices for clarity.

Did beetles use relays?? I'm not seeing that on the diagram.

No they didn't use them. The relay is there to make the park function on his late wiper motor (column switch) work with an early dash switch. They are otherwise incompatible.

Ok... I am following you now... What specific relay would I buy? Think an auto parts store has it?

Just to clarify:  4 wires... low, high, ( switched)  park (keyed hot) and ground this gives you low high and park

Yes they'll have them. Actually you said you had unused ones already in your dash, try one of those. Any universal 12V automotive relay will work. http://www.amazon.com/Absolute...rds=bosch+spdt+relay SPST or SPDT doesn't matter.

Alan, so your way uses no relays, and still gets me park, high and low. Wow. That's the way I need to go on this nightmare. Now, if I knew which one of my particular wires went to what particular connector on my 71 style switch... Seeing that I have a bastard wiper.

No relay....

I wish we'd have notated which wire came from what terminal. Haha. Thanks Alan

 Lightly and quickly just touch two wires at a time to a low amp 12v until the motor moves and go from there to figure high and low...not the best method but it will work.

Thanks guys. Alan, I refer to that as my redneck multimeter. I've done this truck before... Ahha

Just be sure to set the mower gas can a reasonable distance away from the "test bench"

 

Hehhhh

Two-speed VW motors are 5 wire, which as of today he says he has. High (black/yellow), low (black), park power (black/grey), park short (green), and ground (brown). If you don't have that 5th wire on 31b/53e connected and switched properly, the park function will not work. You might get lucky and it'll slow enough to stop when the park cam breaks the connection, but without the back EMF from shorting the motor through the 31b/53e connector for the dynamic braking, it can overrun and just keep going.

I think I will just leave the wipers on for looks and not try to hook them up...

Also to clarify I just use a $6.99 2 position aftermarket headlight switch

Alan, if you just use a 2 position switch, do you have to manually park them?

No, the one hot off the motor supplies power until the cam in the motor cuts power hence to you have park

So it powers the park feature internally?

yes it does.

Thanks.
