Bruce In Philly

No biggie, but my 2009 C2S coupe's heater does not blow hot air when the ambient temps are below say 20 degrees. I had the car fully warmed up with a 1/2 hour drive to/from work with most highway and the heater just never blows hot air. It is warm enough to keep the cabin OK, but my hands were still cold.

Car is parked outside and unsheltered these past few weeks... started up no problems at all. Water temps pop up pretty quickly... oil temps lag way behind.

I had the temp setting on HI and could improve the cabin temps by increasing fan speed to near full.

I don't think there is an issue, but an observation and behaviour unlike other cars I've owned (never owned a Beetle).

Could be clogged up hoses leading to the heather core...
Suggest doing a coolant flush. Flush the system well with a garden hose. Obviously it needs to be done somewhere inside at this time...

Could be specific to your vehicle because my car gets real toasty real quick. I initially thought that with heat source being at the back, and having to be piped all the way to the front might result in mediocre heating, but I was mistaken.

I keep the climate control on 'Auto', this regulates the fan according to how cold the cabin is and what temperature has been set to be achieved. You will need to adjust the ducts to point to the parts of your body that take longer to warm such as your hands. I wear gloves until I know the cabin temperature has been achieved as the fan speed will automatically drop to indicate that state. Also, setting the air to circulate within the cabin thereby reusing the warm air already inside the cabin allows the cabin to heat up quicker and then switching to allow fresh air to come in seems to work for my vehicle.

Hope all this helps.

PS: On cold days the oil temp takes forever to heat up, I keep the can under 3K rpm until the temp hits 180 or higher to avoid pushing a cold engine too hard. Plus, I will not drive the car until the idling rpm settles.

Your climate control operates SOLELY on cabin air temperature, no way to account for radiant heating/cooling effects. Very easy for you to feel "coolish" if your "surround", inside ("outside, unsheltered") and outside, is significantly below your body temperature.

You can help matters a bit by using the (CAREFULLY!!) recirculate mode but with the windows cracked ever so slightly to prevent the cabin atmosphere's Rh from rising significantly.

Below about 34F there will be NO dehumidification benefit from the A/C.

If you had the setpoint on HI but still had to manually raise the blower speed then something is defective.

Yea I think something might be wrong with your heater. Mine gets pretty warm(I do not have to mess with the temp setting, just leave it on auto and 72). I have not driven it in the very cold weather we have had lately(-1 here on a couple days), but yours does sound like it is behaving differently. Not sure if it is the parking outside thing, and having to warm everything up. Good luck and stay warm, we got a little break and it was 45 here yesterday, maybe the warmth is moving east to Philly.

Ditto, I've driven in zero degree weather a few times and I was amazed at how quickly the temperature leveled out.

There's something wrong for sure!

recirculate? fresh air? I know I've forgotten to switch one way or the other at times.

I don't think I have ever had the heater on.

Good candidate for a heated steering wheel. My will blow hot air but my hands are ways cold when it's that cold... or has been sitting outside and gets really cold.

I turn on the seat warmer and it is so toasty that my whole body warms up =)

The heated seats ARE awesome! They get hot almost instantly. Our Acadia take probably 5 min to even begin to feel the heat. My 997.2 I can feel withing a min I'm guessing. Still....a heated steering wheel would be nice. Was that even an option??

My car is actually too warm to be honest. I like 997_Toronto's recommendation on keeping the Auto function going and using your heated seats. In our cold weather the heated seats warm you up really quickly...

You have something wrong with your system. I would have it inspected by a dealer or independent Porsche mechanic. It could be something as simple as a thermostat that is stuck open. It happens to all cars!
