    Default 2CV Windscreen Wiper.

    Does anybody know if there is some way to have a two speed windscreen wiper attachment?
    We get plenty of rain in the South West (Albany).

    Do you want a faster speed or a slower speed than the one you currently have? What battery voltage does your 2CV run from?

    Cheers, Ken

    choose your own speed
    Just remember, the "speed" will never be faster than a standard wiper motor.

    I was just assuming after the battery voltage question that the car had been converted from 6 to 12 volts and the wiper motor is still the 6 volt one and the wipers are going to fast and the OP wanted to slow them down, so suggested this as a cheap easy fix.

    My post wasn't intended as criticism.

    Simply clarification, for the OP who may not grasp the technicalities.

    Fit an intermittent wiper control board like the one below. These were really popular in the 60s and 70s electronic magazines as kits.

    These were the go before manufacturers fitted intermittent wipers as standard kit.

    Get both kits then you can control the speed of the wipers and how often the wipers wipe the screen

    If you don't want to make up a kit of electronics to make an intermittent wiper, you could get an intermittent module from an appropriate wreck. Bosch made one used on several cars in the 1980s and 90s, with a variable interval. We used to own a Lada Niva, they came with a terrible, crude intermittent module from the factory.
    There was a period, early 1990s, when new Nivas arriving in Australia were taken to Peter Brock's company and had quite a bit of work done to make then comply with Aussie regulations, and to be a whisker more reliable. Ours was one of these, a 91 model. One of the changes was to fit a Bosch intermittent wiper module. The original Russian one was disconnected and left in place, an adapter harness was made up and used to join the Bosch module to the existing wiring. TheBosch module was set to a particular setting and just shoved up under the dashboard, you could not adjust the interval only because no knob was fitted to the shaft, and it was stuck in an inaccessible place. The car had only 2 wiper settings, Fast and Intermittent. (same as the Russian set up, except the Bosch module worked better.)

    So...If you can find a wreck of a 1990 to about 1993 Niva, rummage around up behind the dashboard, more or less where the floor mats finish, and you should find a good quality variable intermittent module. You will need to find a knob to go on the adjuster shaft if you want variable interval. It is above the LEFT footwell.

    These modules were also used on more normal cars of the period, but I can't remember which ones. Early Commodores rings half a bell, but only the posh models had intermittent wipers.
    Your wipers still move at fast motor speed, but the module introduces a pause between sweeps.

    In case you aren't sure how they work, here is an explanation... The module is basically a simple timer, every so often (adjustable by turning a knob) it emits a very short pulse of 12 volts to the output wire. That wire is connected to the power supply to the wiper motor. This burst of electricity moves the wipers a little bit, once the wipers are moved a few cm, the pulse disappears but the wipers are no longer in the park position, so the self-parking circuit kicks in and the wipers continue till they are neatly back in the park position. (or still sticking up like 2cvs do...) There is a bit more to it than that, as the self parking circuit needs to be switched out of the circuit when the pule first arrives, to avoid the self park circuit shorting the pulse circuit. But that is all controlled by the module, as long as it is wired in correctly.
