I have been asked about wiper motor park switches so i thought i would repost this wiring diagram. This is the wiring diagram i worked out to get the park switch on my car to work as it should. the wiper motor was from a Vauxhall Corsa C it has a two speed motor and a park switch with two connections. This park mechanism relies on a "broken track" on the motor gear wheel, but if the motor power is not cut immediately the motor runs on and it wont stop. the circuit also controls the two speeds of the motor as well.

Both relays are 5 pin types and both must be wired as shown, the wiper switch connects to earth to operate the wipers  and when the second speed is "on" it also needs to have the first speed "on" at the same time.

This circuit should work for any of the "two wire broken track" park switches on wiper motors out there.

Oh dear.  Looks like I might be needing some new stalks that just happen to fit the column then. I wonder if some earlier corsa or even nova ones would fit.....

the BCM  on the corsa switches the individual items to earth, hence my diagram above, the corsa c wiper motor is cheaper to buy than the other corsa's and is more reliable apparently. i could given a wiring diagram work out what the wires/switch does but it might be easier to wire up alternative switches..

As far as i understand the corsa uses a BCM (body controll module ) and this device switches the wipers and heater motors. the wiper has 5 wires to it. earth, perm live, speed 1, speed 2, switch live.

I don't suppose that the Corsa uses a fly-by-wire setup using the CAN bus, in which case you'll be stuffed as the controls send data messages down one wire and the wipers etc recognise particular messages and operate accordingly.

I've been rebuilding my s3  using a whole corsa steering column. Do you by any chance understand the how the column switches work? 3 wires for about 3 wiper speed settings plus screen washer doesn't seem to be enough. My multimeter tests don't seem to make sense either as the connections never actually seem to be short circuit. The indicator side is just as bad too. Any ideas?

oops paul it doesn't.....sorry

a look at Mk1 escort wiring diagrams shows that they work in a similar way, insofar as the wiper switch earths the motor connections to turn on the single (or double) speed.

the motor will have several connections....(4 into a plug that has also has 4....but different colours from the motor)

The ford single speed wiper motor should have the following colour wires...

Earth =  black / white tracer ........connects to 4 pin plug.....black.........................to wiper switch

1:  blue / green tracer..................connects to 4 pin plug.....red / light green...........to wiper switch

2: green.....................................connects to 4 pin plug......white (ign live)

3: green................................................joined to above.....white (ign live)

4: brown / green tracer.................connects to 4 pin plug.....red / light green tracer...to wiper switch

the two green wires look to be power supply to the wiper motor instead of having them both paired together and connected to the white wires they could be connected, one to a permanent live (park) and one to an ignition supplied live (wipers on). The other two wires will be park and wiper speed one i dont know which way round.

For the wiper switch a standard single pole single throw switch should be fine they have three connections on the bottom and the switch only "clicks" once connect the black wire to the middle connection and the other two wires ( br/g + bl/g) to each of the other connections one position will power the park and the other the wipers proper.

Self park on single speed as well.

I will see what i can work out for you today Daryl.
Comment by Daryl Heasman on November 18, 2012 at 10:17

Dave can you work one out for me please ,i have bought an Escort Estate rear wiper motor complete from a mk 4 Escort ,single speed so just need it to park as it should or can i use the one above
