Hello Everyone,

Posting my first Rennlist posting so if the topic is inappropriate for this forum or if the topic has been discussed in the past, please let me know. I tried to search for it but wasn't able to find one.

I am looking into 993s and noticed option code (beneath the hood) 573 is designated for A/Cs. Most of the cars I've seen had compressors right next to the cooling fan with A/C looking buttons on dash without having the 573 code listed. I read 993 is not known for good A/Cs but are most of the cars not equipped with A/C with some air circulation system mimicking A/C? Or do they come with A/C as a base but the code 573 noting advanced A/C system? I got confused the A/C looking system even without the code.

Appreciate your consideration on asking a somewhat basic question.

 

I don't see option code 573 for mine but I have ac. Ive never come across info to indicate there was a factory upgrade option that would have a code. Maybe usa it was standard, but ROW it was an option? I've never touched mine since buying and it blows cold. Seeme like if you live somewhere hot it has a reputation for struggling but here in MI it can get decently warm and I've never thought the ac could not cut it.

 

I was speaking with couple other folks and think this is a fair guess on the 573 code. Makes sense it might have been a default for NA models.

 

I see this "Option Code 573 Description: 210KW Retrofit kit for 993 M64.05/06" Not sure what it refers to.

Saw this:
993.100.904.00 is 210 Kw/282 BHP retrofit Tequipment kit for M64.05/06 *with* M573 air conditioning

 

I have found a car with this option and it is not a regular A/C but 1. Digital Climate Control Panel: Located on the dashboard, the electronic air conditioning unit usually has a small display and buttons or ***** that allow you to adjust the temperature, fan speed, and vent settings. It provides more precise control over the interior climate compared to the manual system.

2. Control Layout: You would typically find buttons for:

• Temperature control (set in degrees)

• Fan speed adjustment

• Airflow direction (e.g., feet, face, windshield)

• Recirculation mode and defrost options
