Just got done with two 8 hour long drives and found one small issue and one larger/more concerning issue.

Small issue is that sometimes when I go to turn my AC on, it will not turn on and no air blows out. Other times it will turn on and blow out air but the air isn't cold. Is my AC compressor bad or does anyone have any ideas how to fix this?

The larger and more concerning issue that came up is with my brakes. Sometimes if I am making a sharp turn and braking(turning into my driveway for example) my breaks start pumping basically and I lose lots of breaking power. Also if I am braking and hit a bump this will happen. I am at a loss for what is causing this so any help would be greatly appreciated!
