Mine's a 997 '05 but it started doing that a couple years ago. I keep a tweezer in the glove box to pluck the pieces stuck behind the vent louvers. Over time it has gotten less, to the point it rarely happens now. I have not noticed any effect on the system's performance, although I too am in the tropics so I'm running the A/C about 300 days/yr, and the heat very very rarely.

The only thing I notice is in certain combinations of ambient heat and humidity, I get patches of fogging on the outside of the windshield from cold air leaking through the defroster outlets, so at least with the 997 there is more than just a main heat/AC flap involved. I'm not sure what a DIY would entail on mine, but I was quoted several thousand $ to repair everything. Plus the dash would have to be r/r, and from my experience that usually results in squeaks. So I prefer to live with it as-is.

Those are attached by some screws. Part 5 here. Looks like the levers come with the actuator and they are not available separately. Maybe the screws fell off.

Took a look inside the hole to see how the insert piece is held in place. It's held in place with two tabs that are located where the instrument is pointing. The screw holding the pieces under that is still there.
The tabs lock over the edge when the piece is pushed into position and holds it there, at the same time allowing the piece to rotate inside the hole.
Has anyone replaced the hot/cold actuator? Apparently this piece comes with it and most likely the old one is still good.
Otherwise I'll have to come up with a way to bond new tabs onto it. Not sure of their size and height though. Anyone have a photo of an undamaged one?

I hope you sterilize that endo explorer again

Resurrecting an old thread...I am replacing the heater core....seems like this is my opportunity to take that blend door out and foaming it.

There are 2 doors. I don't think you'll have access to the second door from there.

pesuazo

Agreed....may be solve 1 of 2 problems....although (from all the posts I have read)...the other door does not necessarily affect the amount of cold air (for A/C) or heat...with winter coming, I would like something better than "warm" air....it seems that fixing this vent will allow colder air in the summer and hot air in the winter

I was reluctant...but pulled out my good ol' dremmel tool....and got busy.....

What type of foam are you going to use? And where are you sourcing it from?

Thanks.

NuttyProfessor

Don't put the foam back in unless you like doing the job twice. Most people put metal tape that the HVAC people use to insulate duct work and blowers. It has a high-temp glue and will hold up for years.

pesuazo

did not use foam...but used strips along the edges...this was not the final product


None of these pictures was the final product...but you get the idea of where I was heading

pesuazo

I bought the 3M aluminum tape and the strips for the edges in Lowe's Home Improvement....
I also put in some tips here: https://rennlist.com/forums/996-foru...the-vents.html

There is also a White rubber backed material used for industrial duct work
that could have promise, its about 1/6 inch thick and has a shiny white side
and the black side with a peal off adhesive on it.. Stuff is VICIOUSLY sticky..
And its designed for outside weather exposure.. so 100% water proot.. Prob available
from a local commercial HVAC contractor.

Next time the guy is in I'll have to see what the brand name is..

If you dremel the top cap off, do you need to move anything at the bottom? I saw another instruction that suggested you need to.
Further, how did you replace the plastic that you removed?
