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.

11 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 1 / ORIGINAL POSTEROriginal post

This is weird, I have foam pieces coming out of left and right ducts on the dash board, the center dash ducts are clean. Has anybody ever seen this?

POST 2Original post

Quotes source post: 14486067

It's is foam that disintegrates over time. My 2000 with 20k miles suffers from this as well. Someone else can chime in but I think it's from the door that selects hot or cold. You can close all but one vent, get a shop vac and turn the fan on high to get rid of it.

POST 3Original post

Very normal. Lots of threads about that issue in here. Come to PCA breakfast at 7:15 am this Saturday at LePeep at 79th and Quivira and you'll meet lots of other 996 owners to share info with. Great group of folks. You don't need to be a PCA member to attend. www.kcrpca.org

POST 4Original post

Not just a Porsche problem. My 04 RAM had the same issue.

POST 5Original post

I find it oddly satisfying to stick needle nose pliers in there and pull out a nice big chunk. Or, I'll stuff a bunch of it back in the passenger side vent then turn the fans on max so my date needs to go inside so she can go inside and "freshen up"

POST 6Original post

Anyone know what's actually losing foam? I'm assuming the inside of the ducts are lined with it. Or is it just a screen somewhere?

POST 7Original post

The foam is used to cover the diverter flaps. The flaps are perforated; the foam is supposed to make air go around the flaps instead of through them. There's a DIY here from someone who replaced the foam with duct tape... Here's Gator996's photo showing a foamless panel:

POST 8Original post

Bits of foam coming out of HVAC vents. BHMav8r thread in the 997 forum can elaborate more on the subject, the effects as well as the function of the foam and the flappers. How to repair DIY write up and instructions: (in order to do the complete fix, the dash needs to come out). https://www.dropbox.com/s/gja11v6yi6...ement.pdf?dl=0 The material is the foam lining from the two air diverter flappers inside the AC & Heater core air distribution assembly, as 5CHN3LL elaborated the foam does degrade and fall apart as these cars age. First picture is the location of the two flaps within the air-box. The second picture is that of the bad old disintegrated foam on the flapper, third picture is of a repair and what it is supposed to look like, TAP18230 foam insulation tape was used.

POST 9 / ORIGINAL POSTEROriginal post

Hello guys , thanks very much for all the good information, I understand the problem. I think I will try and do the fix as per one of the other post and cut the "****" from the top and remove flapper. Thanks again John

POST 10Original post

What i call a "quirk" of the brand.. My 03 996 has the problem, my fathers 06 997 and '13 Boxster S have the foam in the vents.

POST 11Original post

Before you start this awful job , I suggest you read up on the effect the deteriorating foam has on heating/cooling. In some climates, it makes no significant difference.

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