Still blows plenty hot and cold, although I did have my AC system checked for leaks and flushed out with nitrogen then refilled with freon about 6 months ago.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

13 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.

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

Outcome without a verified action link

I guess a tiny bit of cooler air is still getting through.

POST 1 / ORIGINAL POSTEROriginal post

in my 2003 C4S. there any risk to the heater / air conditioning? Not a daily driver.

POST 2Original post

Nope. Mine blew it all out over ten years ago, and I never did anything about it. Still blows plenty hot and cold, although I did have my AC system checked for leaks and flushed out with nitrogen then refilled with freon about 6 months ago. It was blowing cool but not cold. Figured after 24 years it was due. Now it will freeze your butt off.

POST 3Original post

So what issue do others have with the blending? Mine is blowing foam too (and probably was prior to my ownership) but heat feels hot and ac feels cold. Fixing the blend gates looks like a big job and assume just up to the owner, not required?

POST 4Original post

Once mine blew all the foam out I had problems with the windshield fogging up on cooler days. It would fog up so badly and quickly that it was a hazard to driving. I make a draft dodger that I kept on the dash for a while because I didn't want to do the fix. When I finally broke down and fixed both blend doors, I wished I hadn't waited so long. I still get 1 small strip of fog on cooler days, but it doesn't affect being able to see safely. I guess a tiny bit of cooler air is still getting through.

POST 6 / ORIGINAL POSTEROriginal post

this coming summer here in Deep South

POST 7Original post

I read somewhere that if you directed the flow to the floor, there would be no air flowing out of the defroster. After living with the issue for a while, I tried it. Worked perfectly and no more condensation. Give it a try.

I'd love to hear from anyone who has purchased these. At $350.00 for the set, I see a flap repair in my future though.

POST 9Original post

The repair is simple. It’s also much cheaper than the vent cover bandaid.

POST 10Original post

Mine blew out over the two years I had the car and hadn't noticed any difference with the directional heating/cooling or worse condensation. Guess it might be worse in certain humid/temp areas. I agree, the fix is a lot cheaper than the vent covers.

POST 12Original post

I had to do both fixes. I bought enough material to do my car and had enough for a friend's 996.1. I probably have enough for at least 1 or 2 more.

POST 13Original post

Simon 996.2 on 12-06-2021 07:15 AM posted good pics of the process.
