Also, the fan speed changes upon starting a/c will occur because the compressor has a soft start in the 996.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Whenever I start my car the climate control always automatically turns on.
Anyone know how to set it so whenever I start my car the climate control remains off till I wish to turn it on?
Thank you!
On mine I run the fan speed down all the way and then, release and push the fan button again. The display then reads "OFF" and will remain that way when I restart the car.
I turn my a/c off and run the fan speed down until it says manuel before stopping the car. Sometimes even at that, the fan will speed up like it's trying to reach set temp. w/o a/c on. I'll slow it down again and it is usually fine after that.
Does sound like a dealer setting. Mine stays in the exact same mode it was is when I turned the car off. I'll have to check my Autoenginuity software and see if that is settable. Only oddity (normal tho) is that if I have AC off, with out side air, then turn on recirc (say, like when I pull up behind some truck spewing smoke) to keep the stink out, it always turns the AC on...like you're going to suffocate in the car with only recirc on. In fact, if you switch to AC w/recirc, it will switch to outside air after some period of time automatically...
Same for me. I turn mine off by just pushing the fan speed button enough times to reach the "off" display. It will stay that way until I turn it on again.
Regarding the comment about a/c on recirc: doesn't recirc automatically engage a/c mode? And in auto mode, the a/c will switch between recirc and fresh air, depending on demand. Also, the fan speed changes upon starting a/c will occur because the compressor has a soft start in the 996.
Yes it does, (that's why I said it was normal), but every other car I've owned has never done this. It will switch from recirc to fresh..never from fresh to recirc.
Having owned 4 996's my personal experience is that it matters when the car was built. My first 996, a 99, did not remain in the OFF setting when restarted. I then owned two 2001's. Both of them remained in the setting last held, including OFF, when restarted. My current 996, a 99 (not the same car as the original) always starts in the on position even if turned off prior to shutdown. I have always believed Porsche made the change in operation at the 2000 or 2001 MY. Does this jive with those who are experiencing both sides of the situation? Other than being a niusance at DE events, I find no other reason to be concerned.
Try turning the AC off, then reset the user memory setting.
Not sure with the P, but with my previous BMW 540i the memory includes AC and radio settings as well.
I have this same behavior. However, when I have turned off the A/C, upon startup, it's not like the climate control is really starting (indeed, the fan speed is ZERO), it just seems as though the system is activating. I remember reading a reason why the car does this somewhere. I'll see if I can track it down.
This is a source reference. Confirm exact model applicability in the original material.
