Could be the stuff they use for sealing and I think maybe sound deadening.

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.

9 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 2Original post

I would think the air diverter that switches between heat and cold isnt sealing or making it all the way over when going to cold, so u r getting some heat bypassing that diverter. Is the ac colder when u start the car before the engine has a chance to warm up?

POST 4Original post

Have you checked to see if the cold air is being sent elsewhere? I.E. the defroster or floor outlets instead of the dash? The system should send the air to the dash vents when in Auto for AC unless manually selected elsewhere or broken. Is the foam a dark brown? Could be the stuff they use for sealing and I think maybe sound deadening. Maybe a piece of that has come loose and blocked something. I don't recall seeing an airflow diagram. You can probably get an idea from the PET parts catalog. There's a pdf in the site files or here, http://www.porsche.com/all/media/pdf/originalparts/usa/987C_USA_KATALOG.pdf A weak horn could mean one has failed or maybe something electrical. Battery in good condition? Seems like a weak battery can cause all kinds of weirdness.

POST 6Original post

I had exactly the same problem last year and Porsche have replaced the AC evaporator. That was the cause for not cold AC and grey foam disintegrated all around. I was luck that my car was still under CPO warranty! They told me the main reason why this happen is because the car was left too much stopped without air circulation

POST 7Original post

Those are the same foam bits that fly around in my 996tt. It is probably parts aging, but haven't seen it from my 987...yet.

POST 9Original post

Foam is coming from the diverter doors in the air handler. it will keep coming until it is all gone from the 3 doors, then the doors will not direct the air like it should. This is a serious problem hot air will mix with the cold AC air and lower the temp. of AC output. Your windows will also fog up badly. Its a very expensive repair. Fred in Charleston, SC
