Does anyone know whether it's the same part used over both models?

Coverage and how to read this overview

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.

POST 1 / ORIGINAL POSTEROriginal post

'07 Cayman S. The rear wiper has been sketchy at best since I bought the car. It refuses to work in cold weather & now irrespective of what I do with the switch, it wipes back & forth constantly! I've messed about in the PCM switching between manual & auto & checked the seal around the motor housing & it doesn't look compromised or letting water in. Short of disassembling the tailgate, any ideas?

POST 4 / ORIGINAL POSTEROriginal post

After this morning's drive, the motor seems to be giving up the ghost, it's barely able to wipe if the rear screen is dry. We now think it's worn & the original fault would have been the parking contacts in the motor, but also realise this is speculation. This leads me to another question, swapping the part is easy enough, but Porsche list two: 997-628-080-00 & 987-628-080-00. The model designation is obvious to see in the part numbers,, but Pelican for example list the 997 as the part for the Cayman & I can't see any difference in size & shape. Does anyone know whether it's the same part used over both models? There's a big difference in cost to me if not.

This is a source reference. Confirm exact model applicability in the original material.
