I found that there are 2 vacuum hoses unconnected under the dash board on my RHD 95 C2. Cheers.





2 unconnect vacuum hoses under the dash in the driver side on my RHD 993.

Resirculation flap actuator hose. The white with rubber bend goes to the actuator.
I have never seen a black vacuum hose under there, so I don't know that.

Thanks ToreB.
Where is the recirculation flap actuator located?
Cheers.

ToreB

Just above the hos you found.
You see it from below, but also trough the Climate Control Unit dashboard opening.

Hi Tore, you are also RHD too in Norway? Cheers.

my 993 Tip also RHD, but i don't have such black vacuum tube as well.

Sorry that I really cannot find the re-circulation flap actuator under the dash in the driver side. I think that the PO had deleted it and left the vacuum hose unattended. Meanwhile, i will plug the vacuum hose and may I have the part number of this re-circulation flap actuator? I want to refit it.
Cheers.

Have you pulled the Climate Control Unit (CCU) out and looked directly in? I don't recall being able to see it from under the dash.

Look in the online Katalog on the Porsche website:
http://www.porsche.com/all/media/pdf...93_KATALOG.pdf
Looks like it might be a full assembly with vacuum actuator and flap:
flap 993 572 077 00
pdf page 353/437, section 9: Body

Thanks. How can I pull the CCU out? By some special tool?
And I don't have heat, is it related to this unconnected hose?
Cheers

I checked now, the black tube is not a vacuum line, but a wire harness tube. It is much softer to touch than the vacuum pipe, and there should be wires in it.
Cheers,
Tore

Look at the face of the CCU...there are 2 holes on either side. There are U-shaped wire tools that pull out the unit. Same as used sometimes on car radios, so you could find them anywhere they install car radios.

You can try to cut/bend coat hanger wire to the right size/shape and might work. Or I have this kit I got on Amazon for $10, knowing it would come in handy some day...

Use a bunch of blue masking tape on the dash & steering column to prevent scratches.

Thanks for the advices. I had pulled out the CCU without damage anything and proved that the re-circulation flap actuator was removed by the PO. As well as the heater related hoses at the engine room. I think it is because I am located in the sub-torpical area where heater is really not a must. Is the black color hardness tube just stay unconnected like that?
Cheers
