Dumb question, where's the low pressure A/C port? User manual doesn't help and what im certain is the right answer isn't hooking up. Anyone have a picture?

 

Can we ask what is the original problem?
Sometimes we can save you from some problems.

 

I need to recharge the A/C

 

It's the smaller port, wherever it's located.

Have you run a PSI check on your A/C?

Besides that why don't you use the dealer with a 2021?

Let the pro's repair your A/C on warranty.

 

better check what refrigerant it takes. If its r1234yf...better make sure you can find this type in a can.
And, if you must do this yourself...use a balance (fish have scales) as pressure charging with a gauge is horribly inaccurate.

 

2021 must be under warranty, get it properly diagnosed and fixed correctly - and keep your warranty intact.

 

Welcome to the forum. Good advice here. 🙂
