It's been unusually hot here for the past month or so reaching the mid 30's every day - this is not typical BC coast weather! I have had to use my AC on a few occations in the past weeks as it's just too hot to cool the car with wind. My son was complaining the other day of fresh water coming out of the vents when he was driving. I assumed it was probably a clogged AC drain hose as I never see a puddle of water under the car after a run with the AC on.
I took the car out today and passed some dude in a pickup who was travelling the FAST lane, god I hate people who do that, at about 160 KPH. At about that speed a cup of water came shooting out the windshield vents and soaked me [img]style_emoticons/<#EMO_DIR#>/ohmy.gif[/img] Nice to have AC with you but not the pool as well [img]style_emoticons/<#EMO_DIR#>/tongue.gif[/img]
Anyone know where the drain hose is so I don't have to poke about in this heat searching for it. I searched the forum but didn't find any references to this problem.

hmmmm...sounds like a case of Legionnaire's disease just waiting to happen,,,,,

Drain is located on bottom of evaporator tray(thing with blower motor)...little black hose

probably a bunch of crap in the tray requiring more than just a quick hose flush...but who knows...maybe you will get lucky

I had the same problem last year I believe.
The drain hose is center dash behind the radio. It required taking the center console apart and small hands to get in there.
There is an earlier thread so you can do a search.

I'll try a more refined search with a few key words you guys have mentioned. I was worried that I would have to take off the brittle black plastic cover that houses the fan unit under the hood. I have siliconed it in place as it had gaps in it from warping where the glued backing had let go. I know from my 2 944's that the heat under there makes that piece very crispy and I would have to accept the fact of locating and buying a new one before I started.
My hands are like, well ,big, so I may have to find a little helper [img]style_emoticons/<#EMO_DIR#>/smile.gif[/img]

Well winter is here and the car now rests in the garage waiting for the 6 months of after dinner puttering. First thing I did today was to address the AC drain hose as it was a 1/2 hour job. I removed the console and found the hose. Pulled it off, bit of a tough tug as the factory glued it on. I though I had removed the wrong piece; I looked into the hose and saw and electrical connection [img]style_emoticons/<#EMO_DIR#>/blink.gif[/img] . Now I'm wondering what Porsche as up to with this design. Turns out the reason the hose was plugged is that the stereo installer had let a butt splice fall into the vents somehow; it wormed its way through the vent hoses and finally came to rest in the drain hose 2 years later.
After extrication I noticed the lower end of the hose had become broken down, it was soft and slightly mushy. I also noticed that if put back in place the water would drip into the space between the tunnel sheet metal above the torque tube as it was not one piece but 2 pieces of sheet metal with a 1 cm gap in between (last picture). When the AC drain hose was new I bet there was an extention on the end but not any more. I cut a piece of hose and siliconed it to the end so now the water will drip onto what I assume is the torque tube underneath.

Dave, we should give you the <i><b>Diagnosis of the Year</b> </i>award. Very odd!

Agreed. Nice work Dave. I felt like I was reading Richard E. Leakey's diary (no pun - this is a real guy).

Ah, a familiar tale. I had this several years ago - also got soaked a few times. Dave, the only "extension" on the drain line is that little piece you show in your third photo. Well done on fixing it - it is in an awkward place to work.
