Reported cause
Apparently, Porsche's answer to the problem is a new tailgate/glass.
Leading evidence: 'tailgate/glass' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'tailgate/glass' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Clean car instead' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

The problem is the wiper in the glass is Bl**dy stiff which stalls the motor.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi team,
I'm a new Porsche Owner, just purchased 52plate Targa. And I am very happy!. But the ONLY thing I did not check before buying was the rear wiper. It doesn't work. Any ideas? As to what it could be, fuse, control unit, socket/connector, motor etc.
Any help would be greatly appreciated.
David
David!!
BUT:
It doesn't seem to have a separate fuse or relay. If you drop me an email I can send you a wiring diagram, which might help with the troubleshooting.
I spent some time yesterday morning looking at the non-functional wiper on my 996 Targa yesterday. After carrying out some simple measurements (Thanks Richard for the schematics!!) I found all the electrics are fine. With the rearscreen open and the catch tripped the motor works fine.
The problem is the wiper in the glass is Bl**dy stiff which stalls the motor. I filled it with plus gas, then WD40, but it appears that the internal rubber seal binds with the wiper shaft.
My question is, how do you get the wiper shaft off the screen?
So I cleaned the car instead!
I can't find anything in the manuals or parts lists which is any help. Can you take a photo of the underside of the lid where the shaft comes through the glass?
On my Targa the rear wiper is quite free to rotate with the tailgate open
As with most wiper systems thare is a plastic cover over the spindle and nut and this came off very easily with a screwdriver as lever. I suggest your cover may be jammed on as part of the whole problem.
Yea, I removed the cover, the wiper arm, then the rubber cup, then the circlip and washer. But the shaft in the glass goes through a rather second hand looking rubber bush.
If you look underneath the assembly there is a small arm (5-6cm long) with spring loaded pip that locates in the motor disc. A type of Geneva Gear assembly. It is quite clear that the previous owner/garage has had a go at it. I gave it a tap with a soft headed mallet to see if the shaft would come out of the glass, but my bottle went, as I was so concerned about shattering the rear glass.
I am sure that it should push out and assume that there might be a special tool to push it out. Either that or a new rear glass is the other alternative. But please keep the ideas coming!
Still it looks good ;-)

And it DOES look good!
Apparently, Porsche's answer to the problem is a new tailgate/glass. £2100. They don't sell any of the coupling parts - hence why it isn't shown in the manual.
Apologies for my crass input, it did seem like you were asking a very simple question
I notice that in the Porsche list of parts
http://www.porsche.com/uk/accessoriesandservice/porscheservice/originalparts/originalpartscatalogue/
on page 552 it shows a Targa motor and wiper arm, but otherwise shows no specific Targa parts
As Richard says it does seem like its intergral with the glass - just have to drive faster
