[QUOTE="LDC2335, post: 14792376, member: 82561"] Fellas, I replaced every component of my a/c about 2 years ago and had it tested and recharged at a local shop. It has never been quite right though. I think it's just a matter of taking out or putting in some refrigerant to get the pressure just right, but it seems that adding some causes the compressor to not cycle and stay on, and therefore the air doesn't get cold. And when I take some out, it cycles too fast and air still doesn't get cold. The low and high pressure switches are brand new. in this video, I have the throttle at about 1200 or so and the can is not open, I was just using the gauge on it. When it is colder outside, like in the morning, it gets very cold, and then in the afternoon it gets warm out and the air is colder than ambient, but not ice cold as it should be. I can feel the compressor cycling while driving, maybe slightly faster than I feel it should. Could the intercooler be blocking enough of the condenser to affect the air temp? I wouldn't think so as my engine temps are fine. Any ideas? Is this cycling faster than yours? The part I don't get is that the low pressure switch is on/off at 25/45 psi-ish, so when the outside temps go up, so does the pressure and then it throws everything off. Seems like every season, I am re adjusting it slightly. Take some out? Put some in? I just have nothing to compare it too. Compressor cycling: [url]http://youtu.be/Wq9_q3lC2Oo[/url] [/QUOTE]
