Having an issue with the heater in my 2000 Boxster S. It fogs up the windows when the heater is on. If I turn the AC button on the fog stops but the air temperature is no longer hot or warm even. The moisture coming out seems to have an odd smell to it. It's either old nasty water or perhaps antifreeze. Any help would be greatly appreciated.

I have a 2004 C2 CAB with 120K miles. I am getting bits of black foam material coming from the air vents and from under the dash. Where is this coming from? and how can I fix it? I was told there is a foam "pad" on the air flow box under located under front hood near battery.
My 2004 CS seems to be a little weak to get up & go since I got it last summer, but still much more power than the car it replaced. I wrote it off thinking, "it's not a turbo, so what do you expect?"
I did the plugs and air filters in the fall, and replaced the valve cover gasket on the driver side where it leaked the most. Still no major differences, not that I expected any.
Went out to buy some throttle body cleaner the other day, and on my way to the store I got a phone call which prompted me to turn off the climate control (click the fan speed down to 0, temperature display shows 'OFF'). On my drive home the Cayenne drove *totally* differently. Really ballsy on the pickup, tons of pull.
A few days later, I realized the car was especially chilly / foggy, so I turned the climate control back on. Sure enough, she was sluggish again to get going!
Anyone see this kind of thing before, and know what might be causing it? As far as I know, most cars "back off" on A/C and heat when the driver calls for acceleration, but that's definitely not happening here. Also, with the colder weather I'm not sure whether the Cayenne is engaging the A/C in addition to the heat.
Any insight would be appreciated!
Hi everyone. I have a 1998 996 C2 manual RHD. About six months ago the heater/climate control fan started messing about. Mostly it would work, but now and again it refused. This became: usually worked at first start-up but thereafter usually refused, but might spark up at some point during a journey. (it seemed to me that opening a window[because I was fogging up] kick started the fan, but that may be coincidence)
The little fan under the passenger air vent was a little noisy and sometimes the heater fan would click a bit like a bicycle wheel with a playing card pegged to it.
I changed the ignition switch (read about intermittent electrical maladies being linked to it). No difference. I bought as new (S/H) heater fan and when I took mine out found that the connectors weren't compatible so I had a good look around and put mine back in (I read that when fans stop they stop, they don't work sometimes and others not). I then replaced the little fan under the passenger air vent. Again no difference.
Rather than be intermittent the heater fan has stopped all together now. So I have just replaced the heater/climate control panel unit (klimabetaetigung) with one that has exactly the same numbers as mine. It seems to work fine - I can hear lots of things happening when I change vents, switch aircon on and off etc. But still the heater fan won't do what it should.
I'm at a loss to think of what else I can replace - I suppose the heater fan could have finally given up the ghost after a slow painful death, so I can replace that.
The only other thing that seems wierd is that when I changed the little fan under the passenger air vent the climate control (when it worked) seemed to think the car was around 5 degrees hotter than it really was - put it on max and warm air comes out, but turn it down below 27 degrees (when you know the cab's no hotter than 21) and cool air comes out. I have no trouble with coolant or air con, all checked and serviced by Porsche.
I'm trying to remove the heater control on my 2002 986, so I can replace the malfunctioning LCD. Since the failure of these older LCDs (the radio has the same issues) is such a common problem, I thought there might be a tutorial here, to review, before I go prying away at the dash. But I haven't been able to find one by doing a simple "Heater Control Removal" search. Can anyone enlighten me with a link or the smoothest removal procedure? Spring is almost here, so I need to fix this for driving!
Also looking for the easiest way to replace the partly defective display on the Becker Radio LCD. The 2002 has the security radio with the plug-in display, so at least this is easy to remove. Wondering if anyone has had a successful repair done on their Becker radio display, for less than an arm and a leg?
