I've lived with crappy heat in the car for many years. I just put up with it as the car is not a daily driver anymore (retirement) and we just don't have many extended cold snaps. Usually, we'd get a cold snap, i'd think about this repair and then procrastinate and put it off for no good reason.

With holiday company gone, I decided this afternoon to find this thread and seal up the holes in the deflection panels. I've replaced my radio and had my dash and console parts apart in the past so I wasn't too worried about completing the repair.

Needless to say, I was blown away with the 'after' heat performance...simply night and day difference. I followed 87F350's direction and was able to duct tape all the holes. I was even able to reach the two inner panels without too much difficulty. I can't claim all my tape pieces are perfect and without wrinkles but all the holes are covered and the ductwork is taped back up and looks no worse for wear (thank you black duct tape).

Should have done this years ago! BTW, there was no sign of foam on any of the panels anymore...
Thanks again for the great write up!

Here in Houston where it has been 31 F and 26 F in the morning respectively. GIVE ME HEAT! Oy Vey! After doing the full up fanatical Meir repair for the AC, I ALSO HAVE HEAT! I agree, so nice to have actual heat when it's freezing!

So glad that I taped up my blend doors with more holes than Swiss cheese. It has been brutally cold here, down to -5F, but the heater keeps cabin warm and comfy!!! Great winter driver actually, with a set of snow tires and a hardtop!

Mine blows the same flakes and not so hot air when using heater. The current random cold weather has me wishing it did blow way hotter.

I'll look into fixing it soon.

When the blower box is in Swiss cheese mode the heat doesn’t really work. But, when the blower box is correct the freakin’ heat in these things is a blast furnace. Very nice for those super chilly days. I’m getting foam, but haven’t lost enough yet to do the fix.

....Does this foam deterioration affect ALL 986 model years, or did they make a running change in say....2003, for example, to fix the issue?

...all 986 and beyond: Cayman foam being blown out of the vents

Mine started doing this last year, I thought it was just a filter causing it. So something new to add to the fix list.

Foam drain trays and foam covered heater flaps, what was Porsche thinking? Why not at least plastic? Can't be that much difference in weight.

Gelbster · 05-22-2018, 04:55 PM

Probably sound attenuation?

Cunningr · 05-22-2018, 08:49 PM

Was chatting with a friend who has an old ferrari and does quite a bit of wrenching. He suggested spraying some clear paint into the vent hole before it gets to bad to strengthen the foam bond as a temp fix. Not sure it would work, the idea sounds plausible.

That sounds awful. Smelly and could cause moving parts to bind or lock up. Just fix it right.

Yeah was pretty much my thought on that idea as well. That's why he is driving an Italian car and not a German car! Haha

That guy sounds like a nutbar!

My 25year old was in town last week and borrowed the car to visit some friends. Went out there last night to get something from the car and noticed foam all over the interior...Oh boy. I thought the next project was going to be the new control arm links I recently purchased. I suppose that can wait.

probably because of too hot outside, he did full blast the AC fan that made the inner vent foam materials out of the system.

That's OK. Not her fault, and it is indeed HOT!

On the bright side she is 25 and can drive a stick...gotta be happy about that.

Hey all. The 2004 986 I acquired from a family member in Houston this summer has this issue I have started the "through the heater core" repair because it was leaking anyway.
Can someone give me details on how to get the bottom (footwell) door bushing out? I removed the screw and arm that actuates it, but it seems to be too stuck/attached to the door end to just drop off. Is there a clip to undo or maybe I have to pry it? Don't want to break it.

NEVERMIND. I figured it out. Had to leave the "arm" attached to it and use a interior trim prybar to pop it loose.

Hi gang!

Regarding this issue, I have a question. I understand it effects the heater side of the system, but does it impact the A/C side in any way? I'm in Florida and will never use the heat, but definitely need the A/C to work properly. It won't be worth fixing for me if the A/C side of the system is not impacted.

Tomikaze · 05-03-2019, 08:03 AM

Pretty sure it's going to effect both. Hot won't be hot and cold won't be cold. The doors block the other passages off when you switch from one to the other. Swiss cheese let's the air mix.
