As you know the wiper controls on a 410 are:- off, on normal and on fast. If you want an intermediate wipe it’s a case of a quick turn of the switch and off again.

When the insulation to the wiring on the wiper motor started to breakdown through old age last year, it was necessary to rewiring the wiper motor box. I thought at the time it may be possible to wire into the existing circuit a momentary toggle switch. Judging by some of your other replies in the forum you may have the answer as to whether it’s possible and also knowledge of a wiring diagram?

I would appreciate your thoughts or anyone else who may have done this modification.

I believe that I have come up with a good solution* to Brian’s original query, as posted above, which I’ll publish when Brian has had the opportunity to check it out.

* ie one, two or three full wipes and back to park from a momentary toggle switch

Whilst addressing how this might operate on a 410 I’ve also looked at the 411 (which uses a different wiper motor and switching logic) and I think I have a similar solution for the 411s. If anybody from the 411 fraternity is interested in pursuing it please send me a private message and I’ll email a copy of my suggestions. Anybody that is who is capable of following a simple wiring diagram involving a couple of changeover relays and a timing relay AND is prepared to commit to give me and hence the rest of us the appropriate feedback.
