Can anyone tell me where the low charging connection for the AC on a 2011 Chevy Tahoe is?
Charging AC.

You do you and do what you want BUT, are you going to try and hook up a "Suicide Kit" and charge your own a/c system without having the high side attached to a gauge to monitor it?

Going to use the AC PRO CHARGING bottle.
Like I said, Suicide kit.
Sorry, but if you no idea where the low side port is, are you sure you should be tapping and charging a pressurized system? If you do, be careful.

If it’s empty you need a vacuum pump to pull a vacuum on the system before charging. Also, just be aware that it is illegal to charge up a system you know is leaking. Since it is a closed system, if it is low on refrigerant, you definitely have a leak.

Any chance the cabin air filter is dirty and clogged up?

To answer the original question, the low pressure port is in the accumulator. The connection in the AC Charge Pro will only fit on the low pressure port.
I would suggest you take the head unit with the pressure gauge off of the can or refrigerant and simply use it as a pressure gauge to see what it’s reading or save the $60 at Autozone and take it in to get checked at a shop and have it evaluated.
