Why is climate control always on?

[Bradster]

Hey thanks guys. I guess normal is "normal." Thanks again.

mine doesn't do this. but my 01 BMW did, annoying as hell...

[chitowndad]

what drives me nuts is when I turn on recirculation and it always turns on the A/C. I'm sure it's so it doesn't fog up but when I turn off A/C with recirc on it turns A/C back on after several minutes. Talk abut annoying!

IIRC, I leave my fan and temp on the lowest setting; don't even notice it's on. Am I missing something here?

[demick]

I read in the owners manual that the climate control if set to auto, will run the A/C all the time unless it is below freezing outside.

I simply turn off the A/C manually and it stays off until I push the auto button again. I've never had it come back on automatically even over a period of days or weeks. Perhaps different years behave differently.

Also, I often manually turn the fan down all the way until the climate control turn all the way off. No need for climate control when the top is down.

Drives me nuts. I just hit the down arrow button for the fan until it goes off every time I start it. I had a Z4 before this car and it didn't do that. Hummmm???

It's a convertible. Convertibles are notorious for for small leaks, high humidity in the cockpit, etc.

Porsche defaults the climate control to ON so the demister (along with AC for a source of 'dry' air) can prevent windscreen fogging and also to dry out the carpet, ductwork, etc. of any moisture to inhibit mold and mildew growth (again a common thing in convertibles).

LIOLWT - Live it... Or Live With It !
