I was messing with my wipers today and can't get them to work on high, figured out I need a new switch in the column. I also noticed that Hayne's says this is a two speed motor, so I would think that the switch would have three positions(off, low, and high), but my switch has four positions. What is the fourth position for? Car is a 1973. What am I overlooking ??? Thanks .....David

if position 4 is down, then it's for the intermittent they never hooked up.
some cars have it on the column, but it was never used.


you can, however, add a sort of intermittent
by adding a intermittent relay to your wire harness.
the factory has already a place reserved for that.
however, that intermittent relay only works in conjunction with your
windshield washer, meaning your wipers will run 3 or 4 times when
you activate the windshield washer ...

a article on how to hook this up can be found here:
Wiper relay instructions ...

later,
Andy

So .......... without the intermittent relay, the positions starting from "down" would be ....off, off, low, high, ? This is how they are now, except no high because my switch is bad. Can these switches be repaired or do I have to live with it since they are NLA ??

Andy (IMG:style_emoticons/default/aktion035.gif) ..Does one need to get an additional wiring harness for the relay OR is the factory harness wired for this relay?

you'll need a additional harness with the socket for the relay.
this is/was a original porsche part, never seen it for sale anywhere,
i got mine from a donor car that had it installed.

but all cars (73+) come with the connectors to hook this up.

usually, the lowest position is blocked out by the plastic cover.

I have a '74 and the manual states that this position is for "mist" and the wipers sweeps once every 8-10 sec.s Works for me just as the manual says. I have heard that true intermittents were available on the 916-6 cars.

Ironically my 2002 Boxster has the same feature... seems you have to get the Bozster "S" to get the real intermittent wipers.

Some things never change.
