So my A/C has started acting up in my 2006 Corolla. When I turn it on it blows warm (outside temp) air for anywhere from approx. 5-15 minutes. Then will finally switch to cold. Not even fading from warm to cold, It's as if it doesn't notice I turn the air on for like 15 min. And on top of that once it finally starts blowing cold air it doesn't always stay cold, sometimes it starts blowing warm again, after a few minutes. I've got friends coming to visit from out of state on Thur, and I really want to get this fixed before they get here. With my work schedule the only time I have to bring it in is Thur. morning. Just wondering if anyone has a thought of what the problem might be, and how long it might take to fix?
