Yesterday I had my AC gas refilled and after it started givin out nice cold air but that was yesterday, today morning when I drive the car and used the AC it was only blowing out hot air, it got to 90 degrees and still no cold air, I went for a abit of shopping and after that when I tried it started blowing cold air,
So my question is should it take so long to bring out cold air? And what is the econ button for?
