The ignition switch is also the same one used on VW and Audi.

The first thing you should do if you are going to work on this car is to buy a Durametric Tester to test things with and give the collected info here for more advice...
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.

Hello everyone, I recently got a 996 Porsche 911 for cheap!! I am young and learning how to work on cars on my own. Any help is appreciated.
First problem: The car seems to die only sometimes when I turn the key in the ignition. Other times it fires right up no issues. Ive replaced the battery and am about to replace the alternator today. Do i need to change the ignition switch? The key has no problem going in and out super easily.
Second problem: No ac blows hot or cold air. The screen and every button work but no air blows. What could cause this?
Third problem: Just a couple days ago the speedometer screen shows the gears switching between 4th gear and park while the car is in park. Whats happening here? Ive driven the car hundreds of miles and this just appeared out of nowhere.
I have attached videos and pictures in a google drive relating to the problems on top. Link:

Thanks again for any help!! I cant wait to get this thing restored again to fully functional condition. Of course let me know if you need any more information and Ill be more than happy to provide.
1) ignition switch would be the easiest and least expensive.
2) as with any A/C system on any car it could be anything from a refrigerant leak to bad compressor, or all of the above. This is system with lots of parts that leak or fail.
3) that is showing you a fault in the transmission. It would be best to address that before further driving gets you into the real expensive territory real fast.
The first thing you should do if you are going to work on this car is to buy a Durametric Tester to test things with and give the collected info here for more advice...
1. Yes , your first issue shown in the video that is causing black out on the gauge cluster when putting a key in the ignition is a malfunction ignition switch. Easy swap out. Cheap part. Replace it.
2. Next, I wouldn't replace the alternator until you can confirm it is not producing the correct voltage in operation. That might explain the dead battery but again, you need to confirm. Ref#1
3. The transmission light blinking from D to 4 is a common error mode that points to an electrical fault. My bet it's related to the malfunctioning ignition switch. Get it swapped out ASAP!
4. The AC issue could also be linked to the ignition switch. I've seen this happen first hand. Again, get that ignition switch replaced. Reset any DTCs and report back.
5. You also have an Airbag fault. That usually occurs because you've turned the car on with the seat removed, airbag disconnected, or actually have fault with the seat belt connector.
Moving forward, I wouldn't start loading up the parts cannon until you can confirm faults with a diagnostic tool like the Durametric that is built to properly diagnose these issues.
Report back!
Great advise especially the holding off on parts purchases, that can really drain the funds on things that are not needed, the ignition switch replacement is a great start I have seen bad ones cause all kinds of codes and issues and it is cheap and definitely a DIY project. Welcome to the 996 family.

The ignition switch is also the same one used on VW and Audi. Part number is 4A0-905-849 and you can find this on Amazon or at the Porsche dealer like this:
4A0-905-849-B Ignition Switch for Boxster 986 911 996 4A0905849B (stoddard.com)
or on Pelican etc.
This is a source reference. Confirm exact model applicability in the original material.
