The AC in my '22 Yukon SLT is blowing warm on the drivers side and cool on the passenger side. I believe it's a faulty blend door actuator. I can't find anything that shows me the location of the bled door actuator. No YouTube videos. Please help...also if you think it might be another issue, please let me know. I already tried all of the "reset" methods, (fuses, battery, press buttons) nothing worked.

Did you have the system scanned for any stored HVAC trouble codes, prior to disconnecting the battery?

I know that this does not help you with your immediate problem, but it will help you a lot with future problems.
Do you have, or have access to, a quality bi-directional scanner? If not, I recommend that you get yourself a quality bi-directional scanner to add to your tool box. Then, you will be able to read ALL trouble codes, along with a brief explanation/pointer to the source of your issue. You can test many of the truck's electronic functions with the scanner, in order to determine the source of an issue. You will also be able to reset/delete trouble codes, after taking corrective action. You will literally save thousands of dollars in diagnostic and repair costs over the life of your truck, and you will most likely recoup the cost of the scanner within 1 year.

No, unfortunately I had it scanned after that and it showed no codes.
Is it easy to add refrigerant myself? Can I pick up one of those cans at an auto parts store or is it best to have a mechanic do it?
Likely your vehicle has the 1234YF refrigerant. I have not played with it I know that if you're going to evacuate the system it takes a long time and I'm not sure why. As far as being able to get cans and a cheap hose from the auto parts store do some research on YouTube and on the web to see what you can find .
I have a professional set of electronic gauges. I haven't played with the 1234 YF yet but I probably need to make sure my software in the gauges support 1234 YF and if there any special fittings I probably ought to have them on hand because it's just a matter of time.

I added the refrigerant and that fixed the problem. Blows super cold now. Relieved I did not have to rip the dash apart to replace the bend door actuator. Thank you.
