I believe this was an '84 that we saw at a local swap meet.
The owner said that it has never been functioning since he's owned the car. He did trace the tubing back to the sunroof motor, but that's as far as he got. He doesn't know where the switch is to activitate it, but he did state that there was a button under the pod. I assumed that was for the intensive washer, but did the '84 even have one?

I was just wondering if that car had been fitted with a phone aerial sometime in it,s past.., and they took it off and replaced it with H/L jet washer.
Can,t see a real need for a rear washer, due to the angle of the screen.., obviously Porsche did,nt either.

Actually Porsche did fit some as custom request work. In Phoenix due to our dust storms mine is actually quite useful for cleaning off dust accumulated while parked. You are right that its not likely to be needed much when driving...
In this instance it seems it may have been used just to fill a hole with a Porsche part. Its not a great location for it and those nozzles are designed for quite a power jet...
I used the smaller non-heated windshield jets and located them where it was most obvious - however then your supply tubing has to negotiate the hatch hinge & seal.
I can tell you that routing the tubing has some other challenges too. Mine has its own tank and pump and controller - easier because a GTS doesn't have the intensive system - so I retrofited one and repurposed it... lots of work - used maybe 5-6 times per year (so certainly dubious value - esp. most other places). I do also have a larger rear wiper - which I really like. When it rains here - IT REALLY RAINS and this is a great visibility aid for then and also for clearing all that dust off the rear from the dust storms.

On the 84, the high-volume centrifugal that is used to power the headlight washers could be re-routed from the bottom of the washer tank, through the body, along the inside rocker, and to the roof area in parallel with the hatch harness.
I have not done it, but I have rerouted it on one car.
Instead, I routed the hose to the base of the front windshield area to allow a flood coverage of the windshield directly from the hose. Ghetto, but hidden. It moves a lot of fluid.

I would not use the headlight washer pump for this - its just too powerful. Since you must route in the cabin, you don't want any blowouts anywhere. The small nozzles don't flow that much (and don't really need to for this application).
