A/c issues

A/C operation is really confusing. Do I always have to press the A/C button to turn on the A/C? Even when I haven't turned on the Auto, it seems like the A/C is working without pressing the A/C button, and pressing the A/C button seems to blow room temperature air. Even though it's a new truck, the A/C doesn't seem to be cooling well. What could be the problem? I've read the manual, but it didn't help. Please help. My truck is a '23 SR5."

..That and Go into the radio, under your car settings look for climiate.....turn the AC off. This will keep your setting the same as they were when you shut the truck off.
