Intermittent A/C

Hello,

2006 Cayman S having an A/C issues. In hot weather 100+ A/C works when slowing down or idling. At speed or under easy  acceleration A/C immediately becomes noticably warmer and air flow decreases. cooling fans sound like they are running continously Freon levels appear good. I know 100+ is hot but why cold at idle then warm when moving? As always THANKS

How much R135a refrigerant and PAG oil to put in system after pressure switch replacement?

I had to replaced a broken A/C pressure switch/transducer. System refriregent escape. I’m vacuuming the system first and then will be adding refriregant and oil. The question is how much needs to go into the system?

How do you change the default cabin temperature in a 2017 Cayman S?

How do you change the default cabin temperature in a 2017 Cayman S? I can't seem to find that information in the owner's guide. Larry S.
