I have a 2006 Impala LT and I have been having issues with the AC. Few months ago the air was working great . Then it stop blowing cold air. So I took it to Advance to get it re-charged and it stop blowing cold air all together. When I try and cut the AC on the orange light blinks a few times then cuts off. I also feel/ hear a small jerk and my car hesitates when I try to accelerate. Then I had my boyfriend to look at it yesterday . It comes on and stays on , I even cut the car off a few times and it stayed on and blew cold. Even this morning it stayed on until half way to work it cuts off again and won't come back on. Does anyone have any ideas or suggestion what the problem may be ? Thanks in advance !
