Yep, simple clip for a few pence from Porsche. Part number for the plastic clip and metal retaining circlip were on a post a few days ago so a search should find it easily.
Pop the glovebox light fuse, remove glovebox liner and you'll see the little rod flapping about. I taped mine up with gaffer tape until the new clip arrived.

Probably better than Paul in his [

A great website to store in you favourites is www.clarks-garage.com especially the section titled 'Garage Shop Manual'
Lots of invaluable advice in there, especially in your case at http://www.clarks-garage.com/shop-manual/hvac-01.htm
If that doesn't help you can also download the full Porsche Factory manuals from Ricks site at http://www.cannell.co.uk/Manuals.htm

Original post says it's an 88 S so it'll be oval dash.
Could it be the heater valve has gotten stuck? I believe it's on the pipe between the water pump and the rail running down the side of the engine above the exhaust on the S.
Yep, bang on 1988 S Oval dash,,, When I move the air direction slides I can see the motors pushing the rods up and down, now when I move the temp control should I see movment with that.... and the motor mount or drive unit in the picture above is a little differant in apperance, mine drives from the back corner were as the one on here is more central. If I unclip the drive rod it move up and down ok.
Do you think it could be the circuit board on the temp control ??

yes I've had this problem since I bought my 944 nearly 2 years ago.I would point out that Clarkes garage while very helpful is for left hand drive cars.... I knew what the solution was but could not get round to grovelling under the dash and did not like buying bits without seeing it first.
This sunday I did. It was a lot easier than I thought but hard on the knees.
Yes the clip had failed but the metal clip still hung in there. Being miles from and OPC and wanting to finish the job there and then I decided to make a clip until I could get a new one.
Yes its sad but true you can make the plastic part from a rawlplug of the right size with a bit of stanley knife trimming (you don't need the split part of the rawlplug). So I did, I could not make it stay in the mounting hole so a washer and small split pin did that. For the other end I drilled a hole through the rawlplug, then used that old friend the metal screw block from a large chocolate block electrical connector. One on top, adjust the control bar, one on bottom, job done, full heater control at last. I will get a new clip at some stage and now I've worked out how to get the glove box out it will be much easier.
Also looked at the passenger door - window bearly moving on the upstroke, bit of lube fixed that. The door also does not open from the outside, took the handle off outside, agghh metal fatigue on the end nit dropped off, decided to leave that for a while its either a 2nd hand handle or some creative riveting or welding to moulded parts ( the handles on ebay seem pricey). The mechanism is very fiddly, last time I fixed the drivers door I had to get my daughter to help as her hands were small enough to get in!

More thread resurection...
I have a problem with the turbo - Not quite hot air only... the system nearly works correctly - at most temperature settings it is always hot - like the clip had broken or similar. However, on the "fully cold" setting, it sometimes blows hot, sometimes blows cold, as if it were trying to maintain a temperature. So... whilst I haven't looked yet I am assuming it isn't the clip, or any of the flap actuators or flow control valves, but something to do with the sensing and control system.
Anyone any ideas about vacuuming out the little sensing port on the dashboard, contact cleaner on the pot, or other temperature sensor issues that I can check?

I have a similar heating problem and have been meaning to check the heater control valve located at the back of the engine - and close to where all the fuel vapour purge system plumbing and vacuum lines were before I 'deleted' that recently! - as I've read they can get sticky or become irregular like any vacuum device. The other suggestion on Clarks is it could be an air pocket in the coolant system.
